300 Winch Mag load?

[Guest]

Could someone have an accurate load for Sierra 168grs 190grs to shoot at 1000 yards and more.I have VITA and ACCURATE powder but ok for any other type.
TIA

There is a few around here that shoot the 300wm, they might be out shootin them right now though.

I'm sure someone has a good load to share.

For 170gr. and under, I stick w/ RL22.
For 180, up to 190, IMR7828 seems to work well.
150gr. MK
RL22..75gr.
210M primers, start about 2 gr. below 75gr.

170gr. MK
IMR7828...79.5gr.
210M primers
Win brass
Always start lower, but these are really good loads, for a very fickle Sako 75 300WM.

That 150gr. MK, is simply lethal in my rifle, w/ RL22.

Hope this helps...sakofan..

For the 190 MK H1000 is hard to beat.

My WinM70 in 300WinMag likes the 190SMK with 76grs of H1000 lit by a WLRM primer or 77grs with the F215. Shoots sub moa to 600yds, haven't shot it any farther. Velocity is around 2975fps with 25.5" barrel.

I will ditto S1's suggestion of H-1000 as a best powder for the .300 Win. and also suggest H-4350. I burn a lot less H-4350 (10 grains) in my .300 with super results.
