7mmRM and Hammer 143gr

[morgaj1]

What would be the ideal powder for Hammer Hunter 143gr in 7mm Rem Mag?

H4350 and the likes of. 8133 might be good for speed

Personally I’d try H1000 and if you run out of case capacity before you hit pressure then go faster, to H4831.

I’d go straight to H4350 or Hybrid100V for the 140gr AH but I think it’s a bit fast for the HH.

H1000 with Fed 215M

For that weight bullet in the Rem Mag, i'd probably recommend a medium-slow powder.
The 4831's, Magpro, RL19, RL22, RL23.

If you go with a slower burning powder, your not going to optimize your velocities, and end up with unburnt powder.
