I cast my own bullets a few weeks ago and powder coated them. They are 125 gr RN. When I reload them accordingly to the Lee reloading manual the OAL states 1.125 minimum for a 125 lead cast bullet, however if I seat the bullet at that spec it does not seat in the barrel of either my CZ shadow 1 or my CZ P10C. I have to seat them around 1.092 for the Shadow and around 1.085 for the P10C. So is this ok and if so should I seat them all to the lowest OAL of 1.085 for both? I think the PC might be a little thick perhaps causing them to hang up?? Is that possible?
Also just a note that even at both these OAL measurements they hang up in my case guage but they pass the plunk test in both the barrels.
 
You are probably right that it's the powder coating that's making the difference.
I would go with the length that works in both.

There shouldn't be any over pressure issues with lead projectiles and the lower pressures of cast bullet load data.
 
I would load to the length that gets to almost touching the throat in the short OAL pistol. That would be the best compromise for 2 pistols.

Ignore their numbers. You are not loading for their pistol.

Forgive my ignorance but how do I determine if if it's almost touching the "throat"?? Would it be if I can just spin the round in the barrel without it hanging up on the throat?
 
Seat a round long, push it in - see the mark on the bullet. Seat another round, seating the bullet a bit deeper. repeat until the billet does not touch.

A quarter turn of the seater stem is around 12 thou.
 
Well I just loaded a dummy round and slowly seated the bullet until it dropped in and out of the CZ P10C. It also loads and ejects with no issue so I think I'll try a few rounds like this in both pistols to see how they function etc.
