Love to hear more about your .338 RPM!
I am strongly considering it for next rifle. I have a hunt in WY this october and have my 300prc pretty dialed and lots of related expenses or I would probably get one now.
Hope this message finds you. Looks like you just signed up last week...
I'm getting 2635 at the muzzle, 18" barrel and 2895 out of the 185gr (chrono Lab Radar).
One is set up with a 3-18 and the other will have a 1-6.
NW Montana where most of my shots are 40-400 max.
Guiding Bear next fall, I wanted a setup for close in finishing 1-6.
For how light the rifles are, the recoil is extremely manageable. Energy isn't far off 338win mag.
