Re: 308 win and the berger 215
Don't mind at all, just no clue as to either. When I got the rifle shipped to me I emailed Walt Berger and used whatever he sent me for data if I recall correctly. I picked the charge that was about 1 grain under their max, used Lapua brass, a 210M primer and seated the bullet w/o taking into account how far off the lands it was at all. I just kept seating it a little deeper until it fit cleanly in the chamber.
Remember, the intent of this was to simply put a few bullets down the bore and I used the 210 simply because of the bearing surface.
When I put the first 5 down range at 100 yards and could cover the hole with a dime I was very pleased. I had 30 loaded up so I stopped after 5, cleaned the barrel, packed up everything and went home. Shot #6 went through the buck you see pictured. Then #s 7-10 put down some does.
So, I was very lucky to have a Sako action (kickass by the way) and an Obermeyer barrel (also kicks major ass).
Never put one of them through a chrono. Sorry.
