The problems we face today are there because the people who work for a living are out numbered by the people that vote for a living

[QUOTE=MOONDAWG;937637]Have to raise the B.S. flag [B][COLOR=#0000ff][SIZE=4][FONT=comic sans ms] on this one.
We've got a hundred Beretta 92 FS's in our training division that get 10's of thousands of rounds of (1205 FPS) Winchester Western FMJ's 9mm's put through them annually with zero wear or effects on accuracy. End of quote.
If dirt or concrete chips were being included in the barrel there might be a claim.
I do not believe that FMJs (copper and brass jacketed) can wear out the barrel riflings in a mere 1,000 rounds. A former competitive shooter I know (who also services some of our firearms) wore out his barrel enough for him to replace it in about 15,000 rounds, shooting FMJs. He was shooting a GI model 1911 in .45 ACP. The riflings were not worn smooth just yet at that point, though. Just worn enough to affect his competition accuracy.
He suggested I shoot polymer coated LRNs for practice (I use 9mm almost exclusively) for less wear but after around 1,000 rounds of them, the leading became too much of a headache to clean out, and I clean out the bore after only 100 rounds of these bullets. I have since reverted to shooting FMJs and JHPs for practice and the riflings have not showed any sign of wear after a few thousand of them. Shooting is more enjoyable without having to worry about scrubbing/scraping out all that pesky lead fouling.
