Accuracy was under a 1/2 MOA with both loads, these were run to est. the high end on pressure I have not chronographed them yet
Loads were run up until pressure then backed up to what is posted I would start under both charge weights and work up to them.
What is being found to be the best twist rate for the 300 Norma?
