[QUOTE="Lefty7mmstw, post: 691347, member: 48043"] There are things that make a difference and things that take up time. The bullet and barrel liking each other is about 90% of accuracy. Uniforming your brass helps, but you are using a factory barrel with the generous chamber that it comes with so some things like neck turning are actually somewhat detrimental for accuracy. With a factory chamber anything over knocking off the high spots is to much as your neck fit gets sloppy in the chamber. I don't even bother turning necks in my custom barreled m700 lh 7stw. Nearly every one of my rifles is capable of moa or better over the long haul. The ones that aren't are over 30 cal. I'm still sorting out the 270 my wife got me for christmas last year. I think I'm there but haven't really got it proved yet. Weighing your powder can help, but a lot of br shooters simply dump charge reloads with powders that at best are .1 grain accurate on average. Brass and bullets to 1% total variance or less on weight is good. you said you measure seating pressure, but do you cull those out of a certain range?? The uniformity matters more than the actual pressure. [/QUOTE]
