Leaping the rpm hurdle is no small task in many cases. To quote someone else, it isn't rocket science but it does require some attention to details and some work.
Say a guy decides to try 2 bullets, 5 alloys, and 2 powders. He shoots 4 five shot groups per range session, two each with a couple loads.
That is now 20 different combinations but we need to look at working up a powder charge. Say we try 10 charges with each powder. We are now at 200 combinations, 100 range sessions, and 1000 bullets. I would call this a minimal effort, good results may require more permutations. As we shoot and learn we may alter the original plan.
those bullets need to be cast, heat treated, and aged to get consistent results. That takes time. Lots of time. Some alloys when air cooled may need 3 months of more to settle down.
What is the point of all this? That good, solid testing takes lots of time, bullets, and powder. Those 100 range sessions need to be on days with decent weather. If I can shoot 30 weeks per year with weather that makes for good results, not too windy or hot or freezing, the. I may need a few years to get the results in.
Anyone expecting any sort of solid evidence of anything needs to realize that time is a critical factor. Sound study takes time, a plan, and execution. Shooting a few loads doesn't prove a damn thing.
Who knows, in a few years we may be able to have a good discussion on how to leap the rpm hurdle. We can't do it now because the results aren't in. Heck, I don't even have the bullets cast yet.
Yep, good science is a slow process. It takes dedication, record keeping, and a plan. Anything less is just supposition based on a single result. We also need to keep the absolute bane of science out of the equation- bias. Anyone who has truly studied science knows how easy it is to let bias creep into results. This leads to inappropriate conclusions being drawn.
Now do you see why no data has been posted?
