[QUOTE="greenejc, post: 2809221, member: 60453"] The reason I asked about how many .308 rifles you're using is that I shoot three .308's, 6 or 7 30-06's, including four M1's, two 35s, and two 300 WinMags. I found that I either could try to find perfect loads for each rifle or a load that worked 'well enough' in all of them. Since I wanted to be able to use any ammunition I had loaded for any rifle the cartridge was designed for, I opted for 'more than adequate' in one or two, and adequate in the others in that caliber. With the M1's, I have Shuster gas plugs installed and set to shoot 168 to 180 grain bullets with powders in the IMR 4350 range with pressures inside the operating range of the rifles and groups with iron sights around 2" at 100 yards. For the bolt guns, I use the same loads, mostly with 180 grain bullets, with group sizes ranging from 3/4" to 1.25" depending on the rifle. Your barrel twist should be a 1 in 10" so it should stabilize all practical bullet weights for the .308. If you're only shooting factory loads, getting much better than 1.5" is going to be hard, but that may be good enough for distances to 400 yards on elk.
