I am currently using Hodgdon Universal Clays for my SW 745 (180 gr. Laser Cast SWC with 5.6 gr. of powder) and SW 52 (148 gr. Magtech LWC with 3.2 gr. of powder). Both these are providing me with sub 2 inch groups at 25 yards and less than 2.5 inches at 50 yards.
I now want to build a target load for my SW 952 for the 9mm cartridge. Does anyone have any experience in using Universal Clays for this cartridge? I am wanting to use the Penn 115 gr. LSWC for the bullet.
