* Polishes Bore, Reduces Fouling, Gives Easier Cleaning

Abrasive coated bullets provide effective polishing to remove tool marks, rough areas and high spots in bore and throat. Eliminates the primary cause of lead and copper fouling and makes bore cleaning easier and less time consuming. Long, match type, jacketed bullets provide maximum bearing surface for efficient polishing action. Every caliber kit includes 10 bullets each, in five grades of compound to progressively smooth and polish bore.

Has anyone tried this or something like it. Could one expect to see an improvement in accuracy in a factory barrel?
 
This was started by NECO in California, David Tubb promotes it.
It will smooth up the throat and bore of a factory rifle, and might produce an improvement in reduction of metal fouling, perhaps accuracy. It is also producing a bit of accelerated wear.
I have no idea if it is a good idea or not.
Brownells can't sell you the kit, because of export restrictions on the bullets.
You can make charged bullets yourself by rolling bullets and abrasive between two sheets of glass or steel. The abrasive is embedded in the surface of the bullets. Clean the barrel, shoot five. Clean the barrel, shoot another five. Etc.
Might brighten up a neglected barrel on a milsurp.
 
Used it once.Felt it definately helped with ease of cleaning and fouling.Did it help accuracy?Maybe a little.Definately only use it on a factory barrel.
 
Last resort is where I'm at. I wouldn't dream of doing it to a after market barrel but I'm at the point of re barreling.

I was thinking it could go either way on the shipping since they weren't really intended to be projectiles.

I got mine from Brownells last fall and they didn't mention any restricitons.
 
I got the same results as Longshot; easier cleaning, less fouling along with more consistent velocities. No appreciable changes in accuracy - I don't get to shoot far enough to see if the improved SD helped or not with my gun.
 
I had an old Savage model 12 single shot target rifle. It shot well but copper fouled badly. The bore looked like a hockey rink waiting for the Zamboni to come by. I fire lapped it and the copper fouling problem greatly diminished. The accuracy didn't change. I was using lead bullets, this was a mistake because they expand when they hit resistance and the result was that they abraded the throat and pushed it back enough that the bullets could be seated at least .040" longer.
 
it was around $130 total for 3 kits. as an update i just got in the house from running the first 2 compounds down the barrel of the wifes 280....10:30 at night...gotta love rural alberta. borescoped before there was noticeable machine marks on both the lands and the grooves. i only ran 5 of each as the gun shoots consistent 1" groups already. after the first compound the machine marks are noticeably less pronounced, and after the second compound the machine marks on the lands are gone and the grooves are once again less pronounced. i cleaned between each 5 rounds as opposed to the 10 as recomended... just so i could see what was going on inside the barrel. without a doubt i noticed less resistance on the patches as i cleaned the barrel. tomorrow i will finish it up and try to shoot some groups. this is a brand new rifle and it did shoot very good out of the box but i deceided to lap it since it will be seeing barnes and besides i like to experiment.....time will tell. i doubt it will shoot any better and i am fine with that, i am just looking for a little less fouling with the copper bullets. i will post the final results.
