I wouldn't sweat 2 thou neck length difference, 5 will make a difference though.

I never clean my 260 brass, wipe it off and brush necks, clean neck and shoulder with steel wool when grungy.

All I use is a lee collet, knock the shoulders back at approximately 6th loading with a Redding body die.
so easy to use and no lube needed with the collet die.
Size, prime & charge and seat bullet.

Tested Berger 140 hybrids today with H4350, got to 44 grains, could go higher for sure.
44 was looking REAL good and am looking forward to trying them out past 1000!
Will get speeds next time, I'm just happy they worked at AICS mag length.
Pretty big jump and the VLD's didn't like jump in my barrel.

Thinking hybrids for 1000+ and hornady 140bthp's for the rest.
yeah i figured that out with the 100V. i really like the collet die as its very simple and very effective and im thinking it should help a lot by not working the brass as much as the bushings do and also like that the collet die crimps the necks to the seating stem which should make the inside of the neck very uniformed.

my barrel just dont like the hornady bullets...and yes please let me know how fast those bullets are going with 44g as im at 41.6g and my crony says right at 2840 2850 and 43g was about 2930.
