[QUOTE="heikki02003, post: 280156, member: 15200"] Just posted this over at 6mmbr, but for those that don't frequent that site, here are my findings. [SIZE=3][FONT=Times New Roman]Today I weight sorted some .284 Winchester brass. Needless to say I got a shocking result. I know there has been some discussion as to what brass guys are using in .284 Winchesters; either "straight" .284Win Win brand or necked-up 6.5x284 Lapua (oh the irony). I've read that Jerry Tierney extensively tested both Win and Lapua brass and found "Win brass shot as accurately as the Lapua brass". I know that the Win stuff will need to be annealed though. Anyway, here is the breakdown.[/FONT][/SIZE] [SIZE=3][FONT=Times New Roman]Started with 200 brass. Two bags of 50 with the same lot#, and 2 other bags of 50 with the same lot# but different from the first. I guess that was a complicated way of saying two groups of 100 with different lot#'s.[/FONT][/SIZE] [SIZE=3][FONT=Times New Roman]All brass was fully prepped. Flash holes deburred, primer pockets uniformed, full length sized, trimmed, necks turned, necks deburred, and inside of necks polished. [/FONT][/SIZE] [SIZE=3][FONT=Times New Roman]12 brass were immediately culled for random things like crimps and off center flash holes. [/FONT][/SIZE] [SIZE=3][FONT=Times New Roman]188 brass were weight sorted into groups with one grain increments.
