Usual disclaimer about load data being caveat emptor etc etc. I have done a whole load of load development over the years, yet certain loads seemed always to stand out. Pretty much irrespective of bullet weight or type, for instance, 3.6 grains Bullseye/Ba10/ N 310 does not seem to be able to be beaten in either 38 special (with the exception of wadcutters) or 45 ACP. I have found this to the point where the 1st thing I do is just load up this load and take it to the range, and I have not yet felt that it could be improved upon, particularly in the light of the thousands of rounds of load of element over the years that all seem to come out at basically the same result. I've not yet found this phenomenon personally with Rifle calibres, but Ed Harris has found a similar thing with moderate cast bullet loads in full-size cartridges, 16 grains of 2400 or 13 grains of RedDot not being able to be improved upon, irregardless of cartridge and bullet within quite broad limits. (I've not yet been able to push my cast bullet adventures up to these kinds of velocities yet due to my rather oversized Enfield barrel...) Has anyone else noticed a similar phenomenon?
