Is it ok to shoot .458 subsonic rounds through a .45acp can (TiRant)?
Has anyone done it? |

What is the problem? Too high a volume of gas, or the .458 projectile?
It seems that a 235gr .452 subsonic projectile from a 1911 would have the same gas volume and pressure as a 235gr subsonic projectile from a .458, (for similar powders). Is 6/1000 inch diameter difference a problem? If so, what about shooting subsonic 450 Bushmaster through a .45 pistol can? |

I don't know too many .45ACP cases that hold 26-31 grains of powder plus fire a 250gr .458" rifle bullet at 1900+ FPS.... |

Most subsonic .458 Socom loads are much heavier than 230 grains and use a lot more powder than a .45 ACP. Usually 500-600 grain bullets are loaded for subsonic use in the Socom. if you're loading up some really light bullets at subsonic velocities, it's probably not going to function in your rifle, depending on powder used you'll probably have a lot of empty space in the case which can cause erratic performance, but you should be fine using a .45 ACP suppressor on it. Of course the first time you mix up ammo and accidentally drop a full power round into the chamber with the can on, your can is not going to like it. |

I was just thinking that, if I could suppress it, I would really rather have a .45 suppressed sbr than a .308 suppressed sbr. Since WIlson Combat will eventially be selling .458 bolts and barrels, I got a little excited. |
