Thread: The Importance of Using the Right Data

I thought O'Conner used IMR4831 not H, anyway I dont really like 2213, just used it as an example.

2213sc...h4831sc is great powder in the ol poohseventy..... I started using it when had trouble getting win 760...... that meters so much easier.... the adi site has pressures beside the load data and it can be enlightening..... good exzample was mild loads for the 45/70 same speed load with 2208 has way lower pressure than with trailboss ...scratched my head a bit and looked around and other sources say same thing....
with recent cock up....if have choice between two loads for same velocity on paper the one with lowest pressure will be used by me from now on.....
