Those websites are very reckless with their load data as far as I can tell. My 6mm AR can't even get close to the velocitys that they claim without running into very flat primers and ejector marks!
I have lot's of hand written data that would be tedious to post....You can use the loads that you've found online......just back them off a few grains! That's exactly what I did and the outcome was as expected.....Superb accuracy from an AR platform!
