It Doesn't Get Any BetterSaturday, January 19, 2013
I read all the reviews and postings before ordering. I had high expectations and they were all exceeded. The 14/20 is just the right consistency for polishing and cleaning brass. No fouled flash holes and no gumming up. Virtually no dust.....and did I mention the super fast delivery ????
good media fir brassSaturday, January 12, 2013
The right size for me since it is fine and falls through 223 cases. Just put a used sheet or 2 of dryer sheets and it will take the dust and dirt with them.
The fine grit
mixed with crushed walnut shells.

Blast Media, 40 Lbs, Corn Cob, 14/20 GritTuesday, December 11, 2012
Excellent product and grit for cleaning and polishing brass pistol cases. My reloaded ammo looks better and brighter than factory. Great price and fast, fast delivery.

Not only is this a top notch product but free shipping and delivery in 2 days topped the charts.
Fine cob which works better for my purpose
Good brass cleaning mediaWednesday, November 28, 2012
I bought a bag of the 14/20 corn media after reading suggestions on a couple reloading sites. So far I'm really happy with it after running 10,000 .308 cases through it. I make my own case polish out of a little watered down Turtle Wax and then after that dries I add a cap-full of odorless mineral spirits. Not sure if the mineral spirits is really necessary but it seems to help keep the dust down. The media works as well as the dedicated store bought stuff I got years ago, although the particle size is slightly smaller and there's more "fluff" pieces that tend to be affected by static cling. This makes it a bit messier and more gets on the floor, but at this price I don't care if I'm losing some. The price is great and mine was delivered the next day at no cost.
Economy: good price for my purpose, shipping was free and super fast
I would prefer another option for a slightly larger grit, and better particle size consistency would help
Right product...right price...amazing deliveryTuesday, November 27, 2012
I bought this product for tumbling brass on another reloader's recommendation. It's the perfect size. It doesn't get caught in primer pockets or flash holes. It also isn't dusty even for the small size. I ordered at about 2 pm edt on a Tuesday and expected delivery Friday. Was I ever surprised when it arrived the very next day via UPS. Talk about service. I'm not a high volume shooter, but if I need more, or another product I will definitely buy it from Drillspot. Thanks
ExcellentTuesday, November 27, 2012
Product was as needed to clean brass cases. Customer service was excellent - quick and efficient.
Corn Cob Blast MediaMonday, November 26, 2012
Great product. Fast delivery. Thx
Exactly what I hoped forThursday, November 22, 2012
I stumbled onto this product via a reloading forum and it is by far the best tumbling material I have used. The size is perfect for cleaning cases with the primers already removed, nothing gets stuck in the flash hole. When you are in the habit of buying the packaged material from gun stores, seeing the price of this product almost seems too good to be true.
Fantastic product and service!Tuesday, November 06, 2012
Shipping was wicked fast! Perfect grit for flowing thru primer flash holes of brass casings. I used to go to the local Grainger and get the same stuff but this is so much easier and in the long run cheaper (no fuel, no tax, no time). Drillspot is outstanding!
Fast shipping, great price, perfect size grit.
It would be cool if they had a blend of corn cob and walnut shell media. Unlikely to happen but that is what I do. I mix about 3/4 corn cob with 1/4 walnut to get a bit more abrasive action.
Super fast shippingMonday, November 05, 2012
Ordered on line Friday 11-02-12. It is now Monday @1330 on 11-05-12 and I have my 40# delivered.
Shipped quickly, good price, great for cleaning brassTuesday, October 23, 2012
Works great as a cleaning/polishing agent for brass cases used in reloading small arms ammunition.
Decent price for 40 lbs of material. Shipped quickly.
Corncob for reloadersTuesday, October 16, 2012
10/16/12 Compared to the stuff marketed to reloaders the price is definitely right, especially with free shipping. 40 lbs is a LOT of corncob, though. The 14-20 size is very finely ground and a little dusty compared to the "reloading" kind I'm used to, about the same size as ground walnut. Haven't tried adding liquid Flitz as I do with the walnut but plain it buffs cases to a very nice shine as a second tumble after polishing with walnut. And no more poking pieces of cob out of the flash holes! This stuff flows right through. I'm pleased.
Good buffing quality. Flows nicely around, in, and through brass cartridge cases.
Corn Cob Media for reloadingTuesday, October 02, 2012
Just what I wanted in a media it cleans brass cases better and faster than any media I bought at the sporting goods store and the price you can't beat it the fastest shipping that is was free too. Keep up the good work Drillspot.
works very well with cleaning brass cases
don't think it could be improved

Excellent For Polishing Brass Cases At a Great PriceTuesday, August 21, 2012
I needed corn cob media for polishing used brass cases for reloading ammo. I use ground walnut shell to clean the heavy stuff off but needed something to actually polish them up. This worked great. I added a little polishing compound to it and within 2 hours had bright shiny brass. Large enough to not turn to dust after one use, yet small enough to clean out large primer pockets and not plug up all the cases. At this price you just cannot go wrong. I will recommend this to all my friends on the reloading forums.
Just the right size for my needs and not high priced like reloading companys charge
I cannot think of anything to make it better. It might be handy for the reloader to have one size larger grit but not an absolute necessity
Great BuyTuesday, August 07, 2012
I bought it for reloading. I am very pleased with the product and shipping speed.
Great ProductTuesday, July 31, 2012
The product is exactly what I wanted and ordered. Started using it the day it arrived and it does a great job as a cleaner of brass. Add a bit of polish and brass comes out very shiny. Great price and free delivery. The free 3 business day delivery turned out to next day delivery by courier. Will buy again.

Tumbler MediaTuesday, July 17, 2012
This product was exactly what I needed. It is the most economical source of crushed corncob media I have found. It cleans and shines my brass up perfectly. DrillSpot shipped immediately. I will do business with them again.
It works great and was delivered very quickly
The price, of course. It has gone up since it became popular, it seems
Great Brass Tumbler MediaTuesday, June 19, 2012
This media works great in my tumbler to clean and polish brass for reloading. I also add about 0.2 ounce of NuFinish and mineral spirits (3:1 blend) to the media and the brass comes out looking like mirrors.
Great price and über fast delivery
Maybe make it available in smaller 5-8 lb plastic containers for more convenience
Pleased New CustomerTuesday, June 05, 2012
Product is indeed equal if not superior to others used in the past. Bonus is that price point was much better and included free shipping as well! Almost unheard of in this day and age. No small issue when you consider the product was guite heavy and other providers would certainly have capitalized on this issue and no doubt nicked me handsomely for this provision. In addition to the product service and the bonus of free delivery the ordering process was virtually hassle free and was excellent and significantly beyond any of my original expectations. Would and will reccommend this product and DrillSpot to others. Very professional company to deal with from beginning to end. Thank you DrillSpot and much continued success in all of your future endeavors. Pleasure to conduct business with such efficient and capable pros.
Great Price, Fast DeliveryTuesday, May 15, 2012
I ordered the corn cob media. It was on my door in a couple days. Works prefectly. Glad I found ya!!
Econoline Corn Cob Media 14/20 Perfect for Reloaders!Tuesday, May 01, 2012
Best deal going on tumbler polishing media. It is un-treated but add a little of your favorite brass polish (ammonia free) and clean away. By far the best product at the best price from the best seller with the best delivery! Now....if they would just get walnut media we would be in business! Corn cob works great for light cleaning and final polish but walnut is a little better and more aggressive for tarnish or cleaning mud off or brass or links. I use this media to clean .50 BMG brass in a Dillon vibratory tumbler. I often get mud on the brass and links at the shoots and the corn cob does a good job cleaning that but it is really great for cleaning off sizing lube and final polish after sizing and trimming. Anyway, good stuff at a great price! Oh, grain size is right for smaller stuff too, I use this for everything from 223, 9mm, 45, 308, 30-06 and .50
Great price, great product, FAST delivery!
This product is great! Need some untreated walnut media at a similar price!
Corn Cob 14/20Monday, April 30, 2012
Read about his on a forum. Bought for polishing pistol brass. Corn cob lasts a while but the shooting supply companies prices on this are really high, especially if you add in shipping. I have a 7 or 8 gal bucket so I put it in this. At least now I can change it more often. Makes you wonder why some companies are charging so much. Its a by-product. The profit margin must be very high. Ordered online friday and received it on monday. You can't do much better that that and with free shipping. Slightly finer than some but not a problem at all. Works great with some liquid polish. It's a definite YES buy.
Price, very fast shipping
Looks like it went up in price recently, since I read about it on a forum but still a good price

I use this stuff to tumble and clean brass - it works great, just add a bit of chemical polish to the tumbler. Pound for pound and dollar for dollar, it beats crushed walnut...
It's effective, and small enough to clean small recesses
market an agent that chemical cleans along with it, and keeps the dust down just a bit

Great for Reloading!Tuesday, February 28, 2012
This stuff is about 1/4 of the price of regular corn cob or walnut case cleaning media. Huge savings, and works just as well when you add some media polish.
Cheap, works well

Used the corn cob media and like it much better than the walnut shells. Don't get lodged in small crevises.
Great ProductTuesday, January 31, 2012
Works great for polishing brass cases, and not leaving any media in the primer holes.
It is small enought to get in the cases and not stick as other meida dose
It would be nice if sold and package in large plastic containers like some cat litter is

Awesome deal on a huge bag of corn cob media which I use for brass tumbling. Much more affordable than any other sources.
First TimerWednesday, January 25, 2012
I ordered on the advice of a friend and it was all they had said. Next day delivery and the product is wonderful. I got the 14/20 and it works very well. I think the 20/40 may be better for my polishing purposes. What a great product and company. I am now a customer for life. Thanks drillspot.
Delivery, does what it is supposed to do
Could be shipped in a different style of container
Nice Product and CompanyTuesday, January 24, 2012
The media arrived blazing fast, considering the shipping price, free! Thanks Drillspot. This bag filled 2 five gallon buckets to the rim. The size on the media grit is smaller than standard brass polishing media, but still cleaned the cases up nicely. I realize this media was intended for blasting, so I am not complaining. Thanks again.
Price, quantity and shipping.
Wish the grit size was a little bigger.

Outstanding Product and ValueFriday, December 30, 2011
I had an excellent experience with Drillspot when I purchased 40 Lbs of 14/20 Grit Corn Cob Blast Media. They shipped the item the following business day after the order was placed and I received the package in 2 business days. The quality of the corn cob media was excellent and polishes my brass extremely well. It is the same if not better quality than the Brand name stuff at gun stores. The price was OUTSTANDING, $26 shipped for 40 Lbs! At my local shop, corn cob media is about $18 for a container that weighs 6 LBS. My only wish is that it would come shipped in a plastic container of some sort but for the price I didn't mind going to the store and buying a storage bin for a couple bucks. Bottom line, you will not be disappointed with this product.
Quality and value of the product
Wish it was shipped in a plastic bin or bucket
Great Service, Great Price, Excellent Product!Tuesday, December 06, 2011
Ordering online was very easy to do. I ordered the media online that Sunday afternoon, and their website estimated a delivery date of Monday the next week. My media arrived in two days!! They processed my order that Monday and it arrived overnight at my home. Wow! The media arrived in a large box and was packaged very well. I am now using this media and it works just great on my once fired brass. Great service, great price, excellent product, I can't ask for anything more.
14/20 grit was what I was looking for
I cant think of anything at the moment. I am very pleased with what I got
Corn Cob Media 14/20Tuesday, December 06, 2011
This is just what I wanted to clean and polish brass cases for hand loading. It's a little smaller than what I've been using so it should flow through the primer hole easier. The no shipping charge is a great savings also.
The price is an outstanding value what with the price of brass and bullets going up. We do this to save money so anything you can save on is a plus
I can't think of a thing

I didn't think companies of this caliber existed anymore but they do. I use this product for cleaning my shell casings for reloading. Ordered on a Monday and it was here the next day! Was so impressed I ordered a finer grit bag also. This is an excellent product at a great price with free shipping, what more could you ask for!
Dont change a thing!
Polishing MediaTuesday, October 18, 2011
Outstanding customer service. Good price, easy to navigate web site, and amazingly fast delivery. This quantity should last me quite a while and I will probably share some with friends, but I will be sure to recommend DrillSpot to anyone who may be in the market from some great polishing media.
It is perfect for polishing brass cases.
I would have bought in a smaller quantity, either 10 or 20 lbs size if it was available.
Tumbling MediaTuesday, October 18, 2011
Product works very well. Does a wonderful job of tumble polishing brass for reloading. Initially I thought it was too fine but it's perfect.
Good Brass PolishWednesday, October 12, 2011
I mixed 4 parts Nu Finish with 1 part mineral spirits. I was surprised at the small size of the cob. Not a problem it works great. Cleaned my brass in a vibrating tumbler. Half the price I would pay at the sporting goods shops.
Reloading Brass PolishTuesday, October 11, 2011
Works great! Particles are much smaller size than the other specific reloading brass polishing media I had been buying (for A LOT more money, mind you). This is a good thing since it doesn't clog into the primer flash holes as much. I added a little Nu Polish. It does make some dust, but not bad. It really works well. I am totally pleased. Fast, fast shipping.
Price can't be beat, fast shipment, quality for purpose
If it came in a bucket instead of a paper bag, but not if it raises the price!
Just WorksWednesday, October 05, 2011
This stuff gets rifle brass super clean. Most folks add some type of polish mixed with mineral spirits. I didn't have any on hand so tried it as is. The brass came out bright and clean. It didn't quite have the highly polished luster of the other stuff though. Some mineral spirits mixed with some polish will fix that and I don't have to pick out flash holes anymore. the shipping is first rate and fast. In fact it's faster than other companies who charge for shipping. I will order more but since 40 pounds will LAST A LONG TIME, I don't know when. Thanks for a great product and great service.
It does what its supposed to do
Nothing I know of.
Brass PolishingTuesday, October 04, 2011
Saw the reference to this item on one of the gun forums. Said use with a couple of caps of NuFinish dissolved in a couple of tablespoons of mineral spirits. Combination works very well. Very little particulate gets stuck in the flash hole and none that I can tell in the body.
Worked perfectly in a Hornady M-2 tumbler
Great Deal!Tuesday, October 04, 2011
Exactly what I needed for an excellent price. I use this for cleaning brass for bullet reloading, and its a fraction of the price as the ones branded for reloaders.

Does not plug and stick in primer holes like the old corn cob media I used to use from another supplier.

Nothing. Great service! Great product!
Brass Tumblers Will Like This Product!Monday, May 02, 2011
This is just right for polishing brass cartridge cases in your tumbler. You're still better off with walnut for cleaning brass that's been rained on or has a lot of dried grit inside and outside, but this corncob media is just right for polishing. And 40 pounds is a lot of corncob media by the way!
Bulk rate pricing really saves you money over the 2-4 much smaller packages sold by the shooting sports merchandisers.
A bit dusty, but a spoonful of mineral spirits will de-dust a tumbler bowl very nicely. So will liquid polish.
