Yesterday I was asked if it was possible/safe to shoot a 45 Colt cartridge in a 410 shotgun.

Friend knew about the Judge and the older 45/410 barrels for the Contender. He thought since they used both cartridges he should be able to shoot 45 Colt ammo in his 410. He understood that the lack of rifling would seriously affect accuracy.

My thought/concern is that 45 Colt cartridges are probably loaded at HIGHER pressures than 410 shells.

Has anybody tried this. Does anybody know of any relevant comments/tests.
