7.62x39 reloading data

[jeffc84096]

I am posting some reloading data for information purposes only. Use at your own risk and always be careful. I am using a stock Radical Fireams 7.62x39 upper with a 16" barrel. Elevation here is about 5000 feet. I have tried several powders and now only use AA160. It is more consistent at higher loads. That is why my subsonic average is only 1020 ft/sec. Any higher average and I get 10% above 1100 ft/sec. I get complete cycling as low as 920 ft/sec.

..... I have tried several powders and now only use AA160.

That appears to be a typo.
