Has anyone tryed and 45-70 bullet in a sabot. I was thinking about useing a .458 bullet in a .452 sabot. Will it work? Will the presure be too high? I was thinking about getting a 340gr or 405gr bullet mold. My brother has a 45-70 New England and I thought it would be nice to cast bullets for it and my inline.
Depends on what size your bullets drop out of the mold, or you could resize them a little smaller. MMP makes an orange sabot for .458" bullets, and the black Harvester Crush Rib Sabot for .452" bullets will sometimes work in the larger .50 bores with .458" bullets.
.50 caliber bores range from .499" to .504" generally, so if you have a tight bore, a .458" bullet may not work to good in a standard .452" sabot.
What kind of inline are you shooting?
