So i have been working on this for upcoming deer season.
Ar-15 built by me.
Cal. 7.62x39R
16" barrel 1-10 twist
Lee 160-312
15.5 BHN
3 coats of Hitek #2
Gas Checked
Sized to .3095
170gr. On the money with gc and coating
Seated to crimp groove
Hornady Brass
Ginex SRP
21.4gr IMR 4227
2068 FPS 5 shot average with 30fps deviation.
Shoots well. Feeds 100% smooth cycle and zero pressure signs. Under 1" groups at 100 yards off a front sand bag several times. ZERO leading even with 10 rounds rapid fire. Worked this load up the last few weekends. Then went to casting this bullet in bulk quantity. As it also shoots great out of a .308 win at 2400fps.
