Any do's and dont's when breaking in a new Grendel?
#12
Maybe a slightly smaller bullet due to the harder bimetallic jacket?

A copper jacket is like .008 thick, we’re talking a .001 difference.

I think Wolf or RSA offer a steel case 7.62x39 with a non-magnetic copper jacketed round. While it would be nice to see that in 6.5g I’m good with the performance I’m getting out of Wolf thru my PSA 12” nitride upper, which has only seen Wolf steel.
