Okay guys, I got out today with my .58cal CVA Hawken and tried out the MPP over the chrony and used the "worst" powder possible right?

70 grains Volume Jim Shockey's Gold Super Powder
.020" patching cut at the muzzle
.570" round balls weighed 277 - 278.8 grains
CCI #11 percussion cap
Knight red hot #11 nipple

Chrony was set at 18 feet distance.

Cold clean bore shots:
1405
1416

Swabbed between shots, one patch, both sides with birchwood casey No77 muzzle magic
1431
1439

I'd say the seating pressure with the MPP is very consistent.

I also used the wood ramrod today and it felt fine. Just because not to jerk sideways and I feel everything will be safe to use.

Believe it or not, the jim shockeys gold shot more consistent velocity wise, than the AR15 and AK47 ammo my brother and nephew were shooting over the Chrony.

I always liked to shoot Jim Shockey Gold 3f powder. I never ran it over a chronograph, but I have had it shoot round ball out of a round ball rifle real well.

I don't guess that the MPP would make much difference using BP as it does with the subs. I normally just load to my ramrod mark which most of us do.
That sounds like a another test for you to do since you're the only one with the MPP......

I've got Goex and will be testing it next.
