posted a couple weeks ago looking for load suggestions ....
ended up putting a new scope on last ngt, and tried a few loads. Im happy with it ...ready for november its a win coyote 300wsm with
Vortex 3.5x10x50
it likes 64.4 grns of IMR4350, 168gr Amax , col 2.80 shot under 3/4 @100yrds , seemed to be more accurate with win nickel plated brass than reg win brass ??

heres 3 shots @100

I just started working loads for my new 300wsm. Tried several powder charges and ended up with 63.5grs of H4350. I used 3 shot groups at 100yds, and only changed the power charges. Ended up with this .25" group. .012" jump at an OAL of 2.120 to the ogive. I used Norma brass and F215M primers. Barrel is a Hart, 26" with 1 in 10 twist. My higher velocity charged groups spread out too much. I'm happy with this.
