I have been seeing good results with:
44.5gr of Reloader-15
Nosler 165gr BTs.
COL 2.804in
Neck sized win brass
Lee factory crimp
CCI standard primer
I just chronographed a 5 shot string at 2,525fps (23FPS max spread) out of a 22in tube. I could go faster but the sub .5min groups is fine by me.
I hear that 168 A-Maxes and 45gr of RL-15 is a good load. I started to work up to that load but the weather has kept me from sending any of them down range.
Safety Statement: Start low and work up to the charges listed, they are on the warm side in some publications.
Best of luck, let us know what you settle on.
Oh, deer don't like them one bit!
