PA Conical vs 54 RB Advice

[Indy Durtdigger]

That's one I can't answer. I just went out and mic'ed the diameter of the Minie's ....but they are prepped for shooting. I bump them out to a diameter of .550 plus or minus a few thousands.

I do know that without bumping the base the Minie will drop to the bottom of my .54 barrel with practically no resistance. So, if you know the diameter of the lands, that will tell you something.

I'm going to attempt to memory hole your method. Wish me luck.

I have a Santa Fe Hawken with the .53 cal bore and have wondered if there was a possibility of finding a conical that would load and shoot well from it.
My barrels twist is 1:66 I believe, and I have measured the groove to groove diameter at .533", or maybe that was the land to land diameter... I'll have to double check that.
One more question for @ChuckJonesWagon, do you know the diameter of the as cast Lyman 533-476 before expanding the base?
Regards
