The more I thought about this the more I think for the sake of safety we should recommend that only the ammo designed for any weapon be used in it. Wouldn't want some indiscrimate individual to blow themselves up and then come after us.
No comments on the acceptability of such practices..However, I have received reports of folks shooting .410 shells through the rifle barrel of 12 ga drilling's that featured .38-55 riffled barrels.... :shock:
My dad says his buddy use to shoot 44 spec out of a 410 with mod choke dad never shot it he dodn't trust it and told him to shoot what was ment to be shot in it
