tHANKS GUYS. i'VE DONE SEVERAL LADDER TESTS WITH A VARIETY OF bullet/powder/jump variables with very good results. I have loads that I like and the gun likes. I have already taken elk, deer and antelope with my reloads with excellent results.
I was just wondering if there was some kind of "ladder" test for powders. I lean towards the philosophy that "the heavier the bullet, the slower the powder".
I recently loaded three different powders for my 25-06 using the same bullet, jump, brass, primer, etc. And I got surprising results. I also tried to calculate the M.V. to be the same for all three loads. So I had different powder weights in each. 100 yards, one powder produced a noticeably better group than the other two. So that's what I used to load a ladder test. But have always wondered if there was an established sure-fire way of knowing what powder your gun, bullet, brass, jump, etc liked.
A buddy at work says I'm "over thinking it!" I just might agree with him. (Longtime re-loader, award winning shooter and gunsmith)
