What are some of your reloading procedures for testing new loads? I've been reloading for 22-250 and .257 AI for a few months now and I'm wondering if there's a better way...in other words, I take a minimum powder charge, use it for 3 different groups of ammo with the same bullet, and only vary the seating depth. Once I find the sweet spot for the seating depth for that charge, I then work up the load. That's a great method for finding an accurate load with ONE powder, but then, you have to try different powders to see if you can get it even more accurate. This is where I get confused...Can the seating depth I found with one powder be the sweet spot seating depth also for another powder, or do I have to start all over again and experiment with different seating depths? I do it that way...For example, I'll load 3 groups of matchkings with the same charge of Benchmark powder and vary the seating depth...then I'll load 3 groups of the same bullet with H380 powder using the same 3 differen seating depths, then i'll do the same with varget, and so on....Am I wasting time and money here? should I just find one sweet spot seating depth with one bullet and stick with it for all different powders? Thanks for any help on this confusing question!
