Loading them into the lands (2.26 COL), I've gotten them up to 2200 fps in a 1:24 20" AR platform but the signs said maximum safe pressure. I forget if I was using W296 or 300 MP but it definitely was not Lil Gun. I'm surprised that the Hornady manual shows maximum velocity as having been achieved with Lil Gun and not a slower powder. I will not give the charge weight as I'm concerned some speed demon newbie will start there instead of starting lower and doing the requisite workup. With as many different barrels out there as there are now, one size definitely does not fit all. A lot different than back when there were only 16" and 20", 1:24 barrel choices.
