Nosler 265 gr. 338 LM

[TK Products]

Anyone had any luck getting the 265 gr. LR's to group? I can get the standard deviation down into the single digits (2900 fps) but cant get them to group under .750". I'm shooting an extended action 338 Lapua (3.9" overall) with 96 grains of H1000 0.010" off the lands through a Broughton 1-9.3 twist barrel. The gun will shoot under .250" all day long with 300 Bergers seated 0.010" off the lands. I was just hoping to get better bullet performance down to 1200 fps with the new Nosler. I shot them into gel all the way down to 1200 fps and they did great, now i just need them to group! Maybe they like to be farther off the lands?

From what I've seen, the LRAB likes to jump. Run a seating depth test. .090" off was a sweet spot for the ones I've used.

Nosler recommends a jump of at least 0.050" off the lands. I've found them to be closer to 0.100" which is where the regular Accubond likes to be seated
