Some of my reloads would not chamber in my 45 1911. The boolit is TL. I tumbled them in Lee liquid alox, no sizing. Most chambered ok. I could see a little more bulging around the ones that would not chamber. I bought a chamber checker after I loaded these and sure enough about 1/4 of them would not chamber in the checker. I ran all of those through the shell sizer without the primer punch. There lies my question. How much do you think that will raise the pressure? they all went through the sizer quite easily.
