[QUOTE="rooster721, post: 1020478, member: 40654"] Brass is everything in my opinion (regardless of distance) if accuracy and consistency is what you want... I myself have seen very-dramatic changes in accuracy plainly related to brass alone. Flyers and inconsistency has driven me bonkers the last number of years and I've taken it upon myself to understand *** a guy has to do to eliminate the frustration best he can... I am (ironically-enuf) finishing up my-own tests, measuring the differences consistent brass and the run-out (in-it) alone ([U]and[/U] in its loaded rounds) make. So far, in one of the calibers, I've noted plain-jane minimal prepped brass without any annealing or neck-turning or flash-hole de-burring (basically nothing but, size/trim/chamfer) ...a guy will see lets say a 1.75' group in "a finished load" ...same finished load in brass with a full prep job (anneal/size/trim/chamfer/flash-hole deburr AND neckturn) you may see a shrink to 1.0" maybe less ...same exact load AGAIN, only with that full-prep brass yet sorted for run-out to be (my-case I been going +/- 3thou and less as my special-select stuff) ..and that 1.0" group can be cut by another 1/4"-3/8" !!! [B][I][I]based on what I've seen in my firebird AND so-far as I am finishing up my 338 tests*[/I][/I] [/B] Groups and their consistency have shrunk in an almost unbelieveable size, and best of all the flyers that I could never figure out have basically disapeared... and my groups are as they should have been all along So, in a nut-shell (and in my-own firm opinion) yes-absolutely... brass of different make, lot and prep-level without-a-doubt [U]does[/U] impact accuracy [/QUOTE]
