It oughta be a hoss! And stick with the 140's like I mentioned a day or two ago. Speed doesn't mean chit if it doesn't have the BC to go with it.
Gotta fire form all that brass first though. Holler at me when the brass is ready. We can stretch its' legs one day if you want to drive up again.
I think I might try the "cream of wheat" fire forming. Have 200 pieces of lapua brass ordered that should be here wednesday. Gun should be done in about 2 weeks. Will give me something to do loading all that up next weekend.
