BTW, Hodgdon's online data used to show 18gr as max in the .300 with 125gr bullets and Lil'Gun - but showed low pressure. They've now revised the charges upward and now show 21gr as max with Lil'Gun, giving velocities right at 2400 fps out of a 16" barrel. That's pretty hard on the heels of the 7.62x39
