Ok, I'm sending my AR-15 off for some work and am going to use my FAL in the meantime at local 3Gun matches, so....
I'm looking for a good soft-shooting .308 load for a FAL. Major is 340PF so I need a 150gr at 2300fps. The local matches won't have shots over 175 yards, so I can deal with the 4" of drop (if I sight in at 50 yards).
Using 150gr Ballistic Tips (I've got a bunch on hand), I get 2558fps with 44gr Win748, and 2487fps with 41gr W748. Both of those cycled the action fine with "room to spare" - ejecting cases over 10', and the gas port wasn't even closed all the way.
If I extrapolate from those two points, it's about 24fps per grain of powder, meaning that to get down to 2300fps, I need something like 34 grains. That seems WAY low and I know extrapolating does not work with load data,
Most of the reloading data does not go below 41-44gr Win748, but the Lyman data goes down to 38gr for a 151gr cast lead bullet.
Any suggestions?
thanks
