Some good info on this thread. A neighbor asked if he could have some of my cast and coated 45 bullets. I gave him some and he had all kinds of problems starting with sticking a tight fitting load in the chamber of his new gun. He's a former Ranger sniper special forces guy too but hadn't heard of the kerplunk test with just the barrel.

I inquired as to his process and he didn't use an expander at all. He just figures the case will cut the bullet to size. That particular mold casts a little out of round but they work fine in my gun unsized but I flare the mouth and then taper crimp it back down which sizes it a bit. I told him I'd size some with my push through if he wants to try again but he needs to start using an expander instead of shaving the coating off with the case mouth.
