I have an SPS Varmiter, 26†bbl, 1:12 twist in an XB40 stock. I load 46.4gr Varget; Federal GM brass, cases prepped and neck turned to take off the excess brass; WLR primer; Sierra MK 155 Palma bullets (2156) and COAL of 2.925â€. The muzzle velocity is an average of 2820fps (5fps SD). Will shoot .5†at 100yds all day long. Holds 1MOA to 900yds. Muzzle velocity drops off to the speed of sound at 1000yds. Bullets then spread out to 3MOA.
I have a 31†medium Palma couture blank I'm putting on the rifle. I should get near 3000fps from this barrel. My 1000yrd shoots should tighten right up.
