barrel fouling

[dlaboone]

Has anyone else noticed different amount of copper fouling with different bullets? In my 300wsm mgowen barrel honaday amaxs dont leave any copper at all sierra mk leave a little and nosler accubonds leave alot.

Yes. And the "old" Barnes X (before they grooved them) were probably the worst for me. Could open a copper mine in the barrel after shooting those.
