Thread: 16" 308 mid weight projectile powder

Currently loading 150gr Nosler BT's with H335 in my 16" Tikka bushpig. However i'm finding quite a bit of velocity variance with temperature. Getting 2730 in winter and would quite like to get a bit more speed if possible that doesn't push me into the red come summer! Any recommended other powders to try? Was thinking of trying 2206H is likely to me any better or much the same? Not really wanting to go to lighter projectiles.

Cheers!
