Been testing out Black MZ in muzzleloading rifles and appreciate a few features of this propellant over other m/l powders. While I have found it falling behind 777 in velocity, I also like the milder recoil. I have experienced good accuracy using heavy Minie projectiles and can’t help thinking how the smooth recoil may mean a milder initial pressure? This would keep the skirts from getting blown off of the Minies if this is indeed the case (lower initial pressure that is).
I would like to use it in m/l shotguns but find no loading data anywhere. I have a number of original and replica 10, 11, 12 gauge guns and would like some help working up loads using 1-1-1/4 oz. shot.

We have an abundance of Eurasian ring-necked doves around here and they are tougher than our mourning doves. Would like some loads in the 1100-1200 fps range. I have #7 shot and it does a great job in my modern guns on these critters in such loadings.

So, think this powder has a real potential in shotgun loadings but not finding much help out there.

Thanks in advance,
Calvin
