Can you loan me some of that Lapua brass?
I only have Federal, Hornady & some Serbian crap.

I think I'm going to give the RL-15 a try. The barrel in question has been very finicky in the past. I had a heckuva time getting the 165's to settle down. They get launched with 43.2gr of 4064.
I was perusing my book earlier and checking out the RL-15 info. I may use that as an alternative when I can't get the usual 4895 & 4064to be happy. Never really thought of it as an alternative.
