I have a selection of .50 conicals that never worked very well in my .50 muzzleloaders. Along with those I have some 370 gr. Maxi-Balls that were cast using a high tin alloy and are too hard to load.

Today I noticed that Cabelas is selling MMP .54 sabots for .50 bullets. I'm wondering if I could use these sabots to shoot .50 muzzleloader bullets in my .54s. Two of them have 1 in 38 twist, so I think there would be enough spin to stabilize even the longer/heavier bullets.

Has anyone tried this? Will the .54/.50 sabots work with .50 muzzleloader bullets (some of which have diameters around .502" or .503")? Are there any potential hazards to this?

The .54 is kind of a waste as a sabot shooter whenshooting .45 and .430 caliber bullets; doesn't do anything a .50 wouldn't do better. But it might offer a killingadvantage pushing a sabotted .50 bullet....if it's accurate.
