Re: regarding hunting with sierra match king and 300RUM
I exclusively shoot the 220 grain SMK out of my 300 RUM and have since 2001! I tried different weights and bullets, but this is what worked best for me. I am backing the SMK with 90 grains of H1000, federal 215M, Remington cases, and has an OAL of 3.6850! Muzzle velocity is 2775! I have had really great results with this load! Personal best was 3/4" group at 510yds with two touching!
