Cast bullets in my SKS rifles

[res45]

I've been working on some cast bullets loads for my SKS rifles for a couple weeks using the Lee .312 160 gr.tumble lube gas check bullet. I finally settled on 12.5 grs. of Alliant 2400 the MAX load in the 7.62 x 39 case would be 15.0 grs. This load is very accurate in both my Chinese and Yugo SKS producing identical groups,no leading and cycles both rifles dropping the brass about 5' from my shooting position.

The Yugo shoots a bit flatter than the standard Chinese SKS a rear sight leaf adjustment of 400 meters is required to hit the same point of aim with the cast bullet as the factory 123 gr. ball would at a 100 meter rear sight setting. I used the same 400 meter setting on the Yugo and it shot high by several inches as the target shows so 200 or 300 meter setting is probably going to be more appropriate for the Yugo.

The TL GC bullets were cast from straight WW alloy and water quenched,lubed once with Lee Alox that has been thinned with mineral spirits 1 oz. to the 4 oz, bottle and allowed to dry overnight,gas checks were then seated with a Lee .314 sizing die with no sizing applied to the bullet. Then TL once more and allow to dry before loading,the final bullet weight with GC and lube was 165 grs.
