.401 cast bullet issue

A buddy of mine gave me some .40 brass and 100 ea 180 grain cast TC bullets. I hadn't had a chance to load any until this morning. Fortunately I only loaded ten of them. Once I had them loaded I decided to make sure they would chamber in my G22. The first one in jammed it up tight. I'm pretty sure the cast bullet jammed into the rifling and it took some swearing and I was finally able to get it out. I tried that same bullet in the factory barrel as well as an Alpha Wolf barrel and it stuck in both.

OAL was 1.10" per Lyman load data for that bullet. I also shortened the load by a few thousandths and it still stuck.

Is it possible that those barrels aren't suited for that profile lead bullet? Or is there potentially some other issue I've not thought of?

You need more crimp

First, 1.10" is problay the minimum oal for that bullet. And that short the bullet should not be hitting the rifling. I use TC bulllets at 1.185" and have no problem.

Are you sure it's the bullet hitting the rifling? If it is, you should clearly see marks on the bullet when you extract a loaded round from the gun. I'm thinking you're doing someting to cause the brass to bulge, or not crimping enough. If either is the case, then you should see marks on the side of the brass, or case mouth, when you extract a loaded round.

He is right.

This evening I cranked the factory crimp die down more than I ever had and those bullets feed just fine
