Ruger PC 9mm reloading

I recently purchased a Ruger PC. I have no other 9mm so I will be loading for this only. I cast my own bullets using Lee 2-Cavity Bullet Mold TL356-124-TC 9mm Luger and these are powder coated. I have some Tightgoup powder laying around so want to try it. I am going to be seating the bullet to OAL of 1.10 and plan to use 3.8gns of Tightgroup. My concern is the OAL. I have many books including the Lyman Cast 4th addition with no true listing of the bullet. Is there a book on Lee cast bullets as I can not find one. Any info on this would be great. I already made a few dummy rounds and put them in the magazine and cycled the bolt. they all feed ok and eject ok.

Have you tried the Hodgdon website, they have load specs there

Yes I tried it do not list any cast bullets

Crickets...guess I am the only one that reloads for the Ruger PC Carbine 9mm
