New Henry .44 awesome butt getting an inch or leading just after chamber??

[10mmShooter]

Hi Guys,

I took my new Henry .44 out this past weekend, it cycles and shoots great with the rounds pictured below. Got home and was running a brush down the barrel to clean it and I noticed a little resistance just before the chamber, checked it out and I'm getting a patch of leading about 1-2 inch long just infront of the chamber, no where else, barrel is otherwise clean as a whistle.

I size to .430 the mold is 240 g LFP Saceo and alloy tests to 15 BNH, and charge is mild 9.5 grains of Green Dot(my goto .44 target load for years in my revovlers) chrono's at 975 fps out of my 8 3/8 Smith revolvers, so out of the rifle I imagine is running 1000-1050 or so.

I have a .431 sizer I think I'll try next, then maybe drop the charge back to 9 grains.

anyone have a similar experience??

For what it's worth, SAAMI specs for 44 mag rifle is .431. Handguns are .429 so that might be your problem. I size my 44 mag bullets to .433 for my guns.

Needs bigger boolits or black powder to propel the ones you have.

I think you need fatter bullets,softer wouldn't hurt either.

lube is Thompson blue angel...definitely moving up to .431 and gonna try a few at that size. I think I'll drop some cerrosafe in the chamber and check the bore dimension too.
