I've looked around alot and i cant seem to find enough data for IMR 4320 with a 311299 in .308. I did find enough to point me towards 31-45gr, can somebody point to a reference or just point me to a adequate starting load? Some have used as slow as h4831sc with this 200gr bullet so i'm guessing it is a viable powder...just cant find the data...not in the 48th lyman anyways or even the 44th. Does anyone out there use this for their .308?

I use imr4320 in a lot of cartridges and I really like it. It is so close to imr4064 and varget you could almost use starting loads for either one of those for a reference. Its a little slower than both. My old speer number 6 manual says 39 grains to start on 200 grain bullet for a 2112 fps muzzle velocity and 43 max for 2360 fps. 4064 is listed as 2 grains less
