[QUOTE="26Reload, post: 1889890, member: 99519"] I am loading NEW Lapua 65284 brass for my new rifle in same... The new brass has really tight necks....mic' the ID at .258 in several....no wonder... So I loaded up 2 groups 5 each two different powder charges....5 with new brass 5 with new brass neck resized... In both charges the actually speed was very close...but each new brass without the neck resized had one charge that was out of the norm for velocity...which in turn thru the average speed, ES and SD off a touch.....if I throw out the extreme hi or lo round everything falls into place.....both rounds with single digit SDs.........so I guess now,I have to figure out which I want to go with...as one round is at 2930fps(53.5gr rl26..3.120")...the other 3010fps(54.1gr rl26..3.120")...and being this is my first proof carbon with 150 rounds through it already........i might have to stay lo fps to keep from burning it up.........
