I've got a Henry steel Big Boy chambered in 44 mag. My Accurate mold that is both the 43-240 A for two cavities and 43-240 AG for two cavities cycle perfectly. But I've tried to shoot jacketed rounds (Nosler 240 grn JSP) and some factory ammo - they just don't cycle very well at all. You can force or jiggle it in but...
So... Guess what I shoot!
Funny thing, I ran into a guy at the range that had the brass big boy in .357 and he said that he only ran the Honady FTX rounds because everything else had issues cycling. Anyway, that was day 1 for my Henry, so I had no idea of what shoots well / doesn't etc.
