I have been saying that bimetal bullets don't do good things to a barrel and in the testing they found that the bi metal bullets ruined the barrels for accuracy in 6000 rounds.

I stopped using Wolf years ago when I had multiple stuck cases during a Magpul class.

Now that ammo is like 700 bucks per 1000, I'm glad I started to reload
