[QUOTE="alf, post: 1093344, member: 9543"] So yesterday the brown truck dropped off a few boxes of Nosler 142 LR Accubonds. I sat down and compared measurements from an older box of 140 VLD's..... [U]Berger: [/U] 1.395" OAL .200" boatail length .455 bearing surface [U] Nosler:[/U] 1.440" OAL .240" boatail length .525" bearing surface After measuring, I threw 200 in the vibrator to give 'em a shiny new moly plating, then proceeded to load up a few for testing. Nothing elaborate, 52-55 grains of H-4831-SC, 3 shots for each, and seated them for a square mark on the ogive. The platform is a S/S 700, 26" Bartlein 3B contoured 5R barrel, McMillan Sporter stock, and a NF 5.5-22x50 in Seekings rings & bases, weighing in at 10 lbs 12 ozs, chmbered in a 6.5x284 with a .290" neck, .188" freebore.

Temp was 80 degrees, light swirling wind from any/all directions, and mirage up the whazoo. I shot round robin style, one shot at each bull at each charge weight, three times, keeping to 2-3 minute intervals per shot.
