My rifle shoots nice little groups with a 180 gr Nosler ballistic tip and 76.5 gr of RL-22. I have a box of 180 gr Accubonds that I would like to try. Am I likely to find the best load for the Accubonds in the vicinity of 76.5 gr or do I need to check the whole range of charge weight? Of course I would load a few working up from the min to check for over pressure.
