A little over 2400 - was chronographed but a long time ago and I think that might have only been 27 grains and not 28 (?). I've only got a 16" barrel so pretty good in my view - I also briefly tried AR2207 and one of the Benchmark Powders (either I or II), but found Reloader 7 really well balanced in terms of pressure and accuracy so very quickly gave up on anything else.
