Here is my 2 cents. I have a DPMS .300 SAUM and love it, which is why it has about 1500-2000 rnds through it. It is my primary hunting rifle. Here is why:
I am sure the .308 models can do it too, but not with a 208 grain bullet.
Some days are good, some are not. Today the wind was near zero, very pleasent and rare.
Cold bore five shot group, 100 yards, MV ~2600 (Aaron, I need my chrono back), Hornady 208 A-Max, 57 grains of 4350, CCI Benchrest Primer. Through the spotting scope and with light shining through the holes, it looked like the 5 side of a die (as in dice) with a very even dispersion. I was very happy. This is what I look for; holes that don't walk.
After firing this string I turned to the 1000 yard gong, calculated 8.7 mil of hold-over and drilled it on the first shot. Fired a second and another hit. Amazing considering I was guessing on the velocity.
The last cartridge I had to hang on to because this was a batch of reloads I put together in a hurry for plinking a couple weeks ago and didn't bother to record what they were.
BTW, I have found that Berger VLDs fly like bricks when compared to the A-Max, besides the fact that the A-Max also seem to handle the jump into riflings much better.
BTW, those are 1" squares on the target, and I was using them upside down.
