All the load data I can find for 108/110gr projectiles is for powder I don't have. I have IMR 4064 and IMR 4895. Does anyone have a load using these powders for a projectiles this size?

Thanks,

The 7.62X39 is a small case and needs a faster burning powder.
Just buy an IMR or HODGDON powder of the right burn rate to solve your problem.
One powder does not work well in all rifle cases.
You made the powder choice when you bought the rifle.

Yep, that is pretty much how it works.

I am posting because you asked. I had to find a box of mine as it didn't appear in my notes.

I use 26.7 grains of IMR 4895 with 123 gr Hornady SP. WWLR primer, trimmed case with the lee basic tool. I crimp the case.

No signs of high pressure and no smoky case, no ejection issues. I guess that I've never loaded anything else for this caliber. I mostly plinked with the sks. I would have worked my way up to 26.7 grains, and was satisfied with the accuracy.
I load 25gr of same powder for my .223 rounds, although I use BlC-2 when I have it for the .223.

So, no experience with the 108/110 bullet, this is just what I use for the 123gr.
