[QUOTE="wildcat455, post: 1616227, member: 102653"] The 163 in 1.5 gr I would run as a lot. That's only .1gr of equivalent powder difference, and even if you weigh each powder charge, say on a balance scale, that's about the best resolution you could hope for in powder anyway. (+- .05 gr) Maybe use the other 37 for foulers, sighters, load development, experimentation on the effects of brass weight difference on your groups? I still would have put them in a box in weight order, so that all cases next to each other are very close in weight, and I would shoot them in that order. Just me being anal about stuff. I meticulously prepped and weight sorted an entire lot of 800 cases... not that tough if you enjoy what you're doing... and the fruit of your labor. blackaj mentioned low weight variation. That 800 round lot I weight sorted? 4 grain total weight variation, with 2 300 round groups with 1 gr weight variation each, (248 gr and 249 gr)and 2 100 round groups outside of that group of 600 with also 1 gr weight variation. (247 gr and 250 gr) The manufacture of this brass? ADG. Something to think about. I think they'll be releasing the 300 Norma Mag brass this year if they haven't already. [/QUOTE]
