I chrono'ed some loads this AM. All charges were dropped with Lee hand dippers.
350 gr Laser Cast bullet, starline brass, Win primer, RL7 powder. Velocities are 5 shot averages:
37.6 gr = 1606 fps, 127 sd
41.6 gr = 1590 fps, 52.27 sd
45.5 gr = 1813 fps, 13.52 sd
50.0 gr = 2006 fps, 30.47 sd
405 gr Rem SP, everything else same:
41.6 gr = 1844 fps, 4.24 sd
45.5 gr = 1960 fps, 17 sd
Note that they all kick like ####. The rifle has a Williams FP reciever sight on it, and rocks to 175 yards are no problem.
I'm thinking the 45.5 load with the 350, and the 41.6 load with the 405 are the ones to use. They should certainly topple over any Elk I might shoot at.
