Thread: Testing a conventional approach to load development

It would be interesting to test the sensitivity of a load to powder weight variation. In Gimps 3 shot groups ladder there are changes in POI but I wonder if these would pull in in a decent sized sample.

My experience with "accurate rifles" is that their ladder (say 10 shots at 0.3 gn increments) is often one hole at or close to MOA across an "enormous" powder variation. Ofcourse the change in velocity will tell a different tale as range increases beyond 100M etc but that's a different test.
