I’ve got a Parker Hale P53 with the historic 1:78 twist. I have tried minié balls from moulds made by Lyman, Lee and a custom made mould with interchangeable plug inserts for different hollow bases. I’ve tried ffg and fffg black powder from 40 grains up to 80 grains. Every single bullet tumbles into the target, if it hits the target at all.
The rifling bore is in great shape and the progressive-depth rifling is prominent.
I don’t slam the bullet home onto powder, I weigh the bullets within 1 grain, my lubricant is excellent, I use pure soft lead. What the hell does this rifle musket want to eat?
I know this isn’t a target rifle but it should be able to at least do a 5-6 inch group at 100 yards. Attached are photos of the tumbling targets and a couple of recovered bullets. I can’t get a good picture of the rifling but take my word for it that it’s in nice shape. This musket was made in Birmingham in 1974 and it has had very little use.
