First thing you all are gonna say is "how stupid" but I wonder if it will work. I have these 110 gr jsp bullets made for the 30 carbine. They actually measure .307. I use them in several different 30 cal loads, and thought I would try them in the 7.62x39, which is .311 dia. I used a pb check on them, ran them thru my .311 Lee sizer and plan to shoot them in the 7.62x39. What do you think?
