I was sorely disappointed in these rounds. I tried the 308win light mags, in three different rifles. One which is a long range tactical rifle. And best groups was 3" at 100 yards. Secondly, I chrono' d these rounds, and couldn' t repeat thier velocity in all three rifles. With the target rifle, with a 26" barrel, it was close, but 70fps slower than advertised.

I say go buy them and post your results to add another opinion.
