No Magnums is several you can't do.Kurt

if  you just want  big
don't stub
just shoot 10gage slugs

but  then if you stub a 10ga  over the usual 12 ga  new doors are opened

those big dixy slugs in  the 12 rifled barrels are pretty big
the 500 SnW
or  45-70 are big  and ready out of the box

My thought is that it depends if you are using low pressure pistol rounds or rifle cartridges.  Also depends on the case diameter.  A 45 ACP would be fine I think, but a 30-06 in a stub would probably not.  Just my opinion, I am not an engineer or a gunsmith.  Larry

+1 on what Larry said. I have a .50-90 Sharps on a stubbed barrel and after a year, it's still tight as a tick. However, I only use black and trailboss in it and I doubt that it's ever seen 20,000 psi.

Pretty good advice so far. I think that it depends on the case diameter and pressures seen - also. Stubs are generally in the .8 inch range in diameter. If you can feel safe with a T/C Contender barrel, a stub would be about the same - as long as the barrel put into the stub is .8" or bigger. So the 30-30 case family would be OK as long as you do not exceed 30-30 pressures, a 45-70 (kept to normal 45-70 pressures) would be OK, but a 308, 270, 30-06 would not be; but they are too much for the Contender too. Of course the 222 Remington family of cases should be OK too. A 35 Remington would be OK ( aslong as it kept to normal pressures) as would most pistol cases - but not all. Some of the newer higher intensity cases ( like the 460, 480, 454, etc) would not be suitable for stubbing - IMHO. Good Luck and Good Shooting
