RE: .338 Federal???
there's a write up about the 338 fed in recently, shooting times by lane pearce. He was pushing pills through a ruger mark ll frontier. his best loads went 1.30" moa using barnes 185 grain mrx and varget powder with fed 210 primers. The nosler 210 partition was next with 1.50" using w748 ball powder.
I have a weatherby ultralight in 338-06 that would put those groups to shame.
If things get bad, call a 911 operator.
If things get really bad, call a 1911 operator
