I've got a bunch of IMR 3031 to use up, anyone got any good loads with this powder and 150 to 168 grain bullets. I will of course double check against published data. Thanks
I made a batch of 150 with 3031 using Nosler 168 Grain HPBT. They seemed to be the least expesive bullets I could find and 3031 was the only powder sold by my my LGS that was in the manual. Haven't shot them yet. I used the Speer manual (almost 20 years old) and the the lowest charged rounded up to a whole grain - easier to measure.
I'm kind of curoius to an answer to your question as well. One pound doesn't go far in 308. I calculated 162 rounds.
Be careful with using older Speer load data. Speer/RCBS has gone to a new pressure testing set up, with more realistic pressure yield readings. Alot of data has changed in the last few years- some charges have dropped from older data.
To err on the safe side, you may want to cross reference your loads, with current data.
