In the Sierra Reloading manual they have a seperate section for the AR-15 in 223, instead of a reloads for bolt action. In the 308 section there is no sepperation from AR and bolt action. This being my first 308 I assume that I can use the specs in the reloading manual for 308 in a semi or bolt action.

As usual you need to work up to the maximum load listed but the data in the books is safe for any type rifle with a proper chamber. The difference will be what makes it feed and chamber better, and of course what will be more accurate. I have not had the time to load much for mine but my standard .308 load works well in it. Most on here seem to agree that the DPMS 1:10 twist barrel likes a heavier bullet 168 to 170 being the often mentioned for an accurate load. Mine will shoot sub MOA at 100 yards with 150 grain bullet if I do my job right. I'm loading a grain below a max load with Varget for that one. I have some Sierra Match Kings in 168 to try but have not had the time yet to do it. Need to empty some brass first then reload it and head to the range.

Yes, you need to work up loads for your gun.They may or may NOT be what works in a bolt gun.....both my 308 Savage and DPMS SASS work well with the Lapua 155 gr Scenars, but the bolt gun likes a hotter load than the gas gun.

As a general rule gas guns seem to like a bit softer load than a bolt. I usually start with a middle of the road load and then go up from there. Too far to the low end and your looking at possible short strokes and too high just pounds the buffer too much. I've never found the max load to be all that accurate in my stuff anyway.
