Guys I just bought a Schumann barrel from a member here it's says its a .400 cal

I looked on the Schumann sight and see .400 short chamber and 40sw barrels what's the difference??

I tried dropping my rounds in it but there not going in all the way?

Is this the wrong barrel?

Does something need to be do e to the barrel to work?

A lot of aftermarket barrels are short chambered so a gunsmith can set the headspace when building a gun or replacing a barrel. It just needs the chamber reamed a little deeper. Their 40 S&W barrel is probably the same thing that doesn't need fitting.

Short chamber means the chamber wasn't cut to full depth. They do that so that the gunsmith installing the barrel can set the headspace unique to the gun it's going on but still save wear and tear on the gunsmith's reamer.

ETA: Toolguy beat me to it while I was typing.
