Wait till it's below zero, then try that load. Or next summer when you are shooting rock chucks. You'll have to start all over. The powder will be a dude when its cold, and you'll have trouble opening your bolt next summer, when it hot out.
Just my opinion.
I bought a brand new set of Cooper's, 10 ply. The second day I was driving along this fence, and a dead tumble weed poked through the side wall. Took them back and had them put back on my wore out Toyo's, and have been running Toyo's ever since.
I'd stay a long way from Cooper's.
Guy I shoot full house loads in my .44, too. We were at this range in AZ, and this guy wanted to shoot my pistol. I said get a hold of it. He touched it off and dam near dropped it. He said "Why don't you down load this a little?" I said "Why don't you stick to a .38?"
My Father used to say, "People will forget what you say, but they will never forget how you made them feel"
The feeling will live with your Great grandson a long time.
Scott, it is called La Grande. It is on the east side of Oregon, in the Blues. I built most of the Boise Cascade mill there, several years ago. It used to be good hunting. I think they have real short seasons, with lots of hunters. Good Luck to you.
