Wondering if ----- ?

I have a GEMTECH suppressor for my Kimber 1911.

Also have a TC Encore 45-70 rifle barrel.

.452 vs .458" ?

A .458 cast will drop thru the suppressor with no interference.

Wondering IF I can buy a WITT threaded adapter, (I have used several on other rifles) put it on the Encore bbl, attach the can and shoot sub sonic loads within the parameters of the 45 ACP can (no faster than 1000 fps).

I would be thinking that the PSI limits are a lot more important than the FPS limits. Does the maker give any limits for the max PSI?

That could work as long as;

there is sufficient clearance for the .458 bullets in the suppressor after being threaded on the Encore barrel.

The loads are kept sub-sonic with lighter weight bullets using powders similar to what is used in the 45 ACP. The use of 300 gr or less bullets loaded over Bullseye would be suggested.

Heavier bullets with slower burning powders, even though sub-sonic, may have too much exit pressure and damage the suppressor.

And you never ever fire a regular 45-70 rifle load through the suppressor.

All the above is conjecture on my part based on considerable experience with numerous different suppressors. My 45 ACP suppressor is used on a 45 ACP pistol and a M98 Rhineland conversion to 45 ACP with standard 45 ACP ammo. If you try it be very careful about the loads and make sure the suppressor is co-axial with the bore.
