I'm glad to see someone using the Roberts. I have a Remington 700 Classic Stainless that I love. I handload to get decent velocity out of the round. As I'm sure you are aware even the +P loads are anemic. I use 115 gr. Winchester ballistic silvertips and H4831. The only manual that loads the Roberts acceptably to me is the barnes manual. Barnes bullets are harder to push down the barrel than other bullets. I generally use the above bullets with 50 gr. on H4831 and a Federal 210M primer. I seat the bullets .015 off the lands and get honest 1/2" 3 shot groups out of the rifle. The rifle is bedded and free floated and the trigger has been adjusted to 2-12 lbs. Over my chronograph I get 2942 fps. This is a 10 shot string average. I use the rifle as my primary deer and feral hog rifle in Oklahoma. This load has never let me down even on a feral hog weighing just shy of 400 lbs on my cattle scale.
