Gentlemen: I've made the jump and started reloading. Lots of fun, with first good results. Question is the following:
I have three recipes, all with different max powder charges.
1) 60.5gr (24"barrel)
2) 57.5 (26")
3) 62 (24")
Corresponding velocity is 3000fps. I have a 22" barrel, no pressure signs and average velocity at 2940fps with a sub-MOA group at 60.2gr.
60.5 and 60.8 produced comparable, but not quite as good groups, and velocity crept up to 2980.
Given my shorter-than-recipe barrel, should I make 60.2gr/2940fps the point to fine-tune around? Meaning, is it correct that a shorter barrel will cost fps-per-inch? I think I've read that somewhere, but can't recall -- any suggestions would be much appreciated.
I have no interest in pushing the envelope in terms of pressure.
