Thoughts? Other than the chamber and receiver getting dirtier, do you think this ammo would preserve the barrel a bit in an ar15 longer given it has a "copper" jacket. I haven't been able to find anything to confirm or deny this.

I've seen that and that was with the bullets that were bi metal. Besides, that amount of rounds shot at such a high rate, no wonder they shot the rifling out.

Exactly. Unless you are planning on shooting more than 5000 rounds at a high rate of fire out of your AR before replacing the barrel, bi-metal or copper jacket doesn't appear to matter much. So no need to worry about preserving the barrel. They also concluded the bi-metal stuff is cheaper even if you have to replace the barrel.

Probably a good idea to have spare extractor parts too then. Looks like I have a shopping list now
