Home Forums Reloading Big Game Rifles 300 WSM pet loads?

I could never get decent speed out of R19 or R22 either.

Learning how to reload on a couple different(picky?) Sako .300WSM's(roughly 800 rounds of various cobblelations) puts H4350 in the lead for all around good powder. Brad got me started on it and it works.

N550 is a good choice for the 150/165's but it is scarce and spendy. IMR4831 goes well with 180's.

Notes show some 'better' loads at
2930-80 with 180's
3050-3130 with 165's
3075-3250 with 150's

Mostly Nosler bullets, 215's or 250's(nearly identical fps, accuracy BTW) and W/W or Federal brass.
