[QUOTE="Tac-O, post: 1919852, member: 109994"] I just used my magneto speed Sporter for the first time today. I'm wondering about some numbers I got and if anyone can tell me the most likely culprit of the variation. Is it my bullet powder primer combo, my hold and recoil absorption, my loads, or something else? Here's a picture of my results. I think that it's more obvious on the second group that it's likely the bullet powder primer combo. I need to try it with Winchester or magnum primers. On the first, I find it odd that the ES and SD are so good without including the worst 3. Or is it just that my sample size is too small at 9 rounds? My loading procedure is the following: -Deprime -0000 steel wool on neck to remove soot -Lube outside of case with Lee case lube -Brush inside of case mouth... Brush usually has a the tiniest bit of lube on it -partial FL size to bump shoulders 0.003 -wipe off lube -trim, chamfer and deburr with Lyman vld -weigh every charge w/ rcbs 505 balance -seat bullet (TIR <0.002) -light crimp with Lee FCD [/QUOTE]
