Powder loads

[Gobbler36]

Question for you guys
Wondering what the max load I can get to push a 340g bore driver the fastest possible out of a Mr-x with triple 7 and musket caps. I think the advertised is 120g by volume but wondering if you can do any more?

Check your owners manual. I thought mine said 150 grains by volume but I’d have to look again to be sure

150 grV is the max charge recommended for non-BH209 powders for most off-the-shelf muzzies (including the Accura).
