Will A .45 Suppressor Fit A .458 Socom?

[MASTEROFMALICE]

I'm building a big-bore AR and one of the considerations I'm giving is this. If I have a suppressor for my .45 ACP, is there any reason it couldn't be used on the .458 SOCOM? The bullet diameter is only .007" larger but I really don't know the tolerances the suppressor will allow.

If the tolerances are great enough, would the .45 suppressor allow a .50 bullet to pass through?

ballistics of a 45-70, muzzel energy of a .308 through a .45 acp can.............1 shot & your can will look like a wyile e cayote blunderbuss

yeah, I would think that pressure would be your problem, not bullet diameter. You'd be running a big-bore rifle round through a can designed for a low pressure pistol round. That looks like a recipe for catastrophic failure to me.

You need to contact the manufacturer of the can directly. They will be able to tell you what will and will not work. DO NOT take the word of anybody on the internet. (no offense guys, but if you say, oh, yeah, sure, it should work, no prob-- BOOOM!)

Most .45 cans are designed for pistol pressures.

Understood.

I actually didn't know pressure was a factor. I had assumed the can served more as a baffle and a cooling device for the gas.

I'll contact the manufacturers but from what I've heard I won't keep my hopes up.
