abrasive reloads ???

[Ol` Joe]

I saw a bullet , i think in the cabelas catalogue, that has abrasives and treats the bore when it is fired. Does this work? And if so, what exactly does it do to the bore and will it improve accuracy? Oh also, will it help older bores. Any info on this would be helpful

They are supposed to polish the bore and help with fouling and improve accuracy. They also round off the rifleing edges and extend the leade as they do it. I had a smith lap a bore for me (factory) that did the same thing as the bullets, and it did improve the ease of cleaning and reduce fouling. The barrel wasn`t any more accurate after then before that I could honestly swear to. The rifle did however seem to shoot more tight groups before they started opening then prior to the lapping. This is more as in 5-6 good groups, instead of 3-4 before they went down hill.

I`ve seen a couple different brands advertized, but haven`t used any of them. I personally don`t think much of them, but others swear they do wonders.
