First follow the sticky on optimizing berger bullets on this site it gives a good starting point.
I loaded varget in 33, 34 and 35 grain incraments seated at 2.209", 2.247" and 2.287" this is based on a coal measurement with the 95gr berger in my gun. I crossed referenced data from 3 sources to get my starting point on the berger comparing similiar bullet in that weight. Also note the measurements are with a stoney point oal bullet compartator.
The attached target is 2 shot groups with powder going top to bottom and coal depth going left to right. It is very obvious that the 35 grain loading is the best and it prefers the 2.287" coal.
