Thanks to Misery-Whip sending me some to try, and taking the time to try and see what works in my Henry. if i keep the flat top bullits COAL under 1.6. and it didnt matter if it was 300 gr or 255gr above 1.6 they would not cycle. i settled on 1.585 and all work great. oddly enough though the 240gr round nose would cycle flawless at 1.625.

I will be headed to the range friday to see how they each perform down range.

The bullits i was sent were all sized to .452. and the 255gr i cast i did not size as they came out of the mold at .453, I juar tumble lubed them and loaded them and they chambered easy.

again thanks everyone for your help getting me started in this wonderful world of casting.
