@Boar Freak
Had a look through all my manuals but none of them list anything bigger than 150gr.
But I did find this info on the Reloaders Nest website
7.62x39 Russian @ www.reloadersnest.com
Unverified load 4133 in caliber 7.62x39 Russian
If your after a subsonic load then I'd recommend using Trailboss as your powder.
Cheers
Pete
