I shoot the .308 208 grain AMAX bullets out of my R700 5R milspec, and they work great. The muzzle velocity is at 2720 feet per second. I tried the RL 17 but turns out in a side by side test that the IMR 4320 produced a higher velocity. I did have to seat the bullets out past 2.8in (which means loading one at a time), but the accuracy achieved was well worth it. The last time I was at the range I made a five shot .4 inch group at 300 yds and another 5 shot .9 in group at 500 yds.
