I ordered some PPU 150 grain .311 bullets for my 7.62x39 and Argentine Mauser. When they came. I noticed they were longer than Speer flat bottom bullets.(boat tail) I had an idea what to do as far as loads. Drop the staring data by 2 grains. And load at that. But i wanted to be sure i was correct. Looking through my books couldn't find any boat tail loads. Then i grabbed one of my Hornady manuals. And they had boat tail bullets listed. My idea was right. It's always good to verify too.
