52.5 grains of RL17, bullet off lands .050 works well in my rifle. My SD & ES are single digits. The rifle is very accurate.

testing H4350 this weekend. Starting at 50.0g and going up up in .1 steps.

 

[Keith Glasscock]

Start with a .010 jump. It should shoot somewhere between 50.8 and 51.5 depending on the barrel. At least that is what I found with my lot of H4350


Look for 2820 to 2850 fps it should shoot in that range.
