Tired,
I have practically shot the barrel out (1300rds) of my 7mm RM Sendero, mostly shooting the 150gr Nosler Ballistic Tip ahead of 67.0grs of RL22 and a CCI BR2. I chronographed it earlier it its deer smaking career and it was 3130-3150fps. This load has produced 3 shot groups of .288" @ 100yds and 1.75" @ 500yds and busted numerous 10oz plastic soda bottles (filled with water) @ 500yds. Longest shot on a whitetail buck was only 435yds, but he definately stayed there and waited for me to feel that "boney" head.
Pretty sure this load is max or right at it. I have taken it up to 69.0 grs but saw no improvement in accuracy and the recoil/noise was up there! I hope you enjoy that rifle as much as I've enjoyed mine. Good luck. Johnny K.
