I've been thinking about 2400, too, altho I don't know if I'd want to go beyond Paco Kelly's 23.5grs for that weight bullet, & he's using the load in a '92 action rifle, which, so says he, is the strongest action among the short cartridge chambered rifles, (Marlin & Win. '94 being the other two).Another possibility maybe Hodgdon's L'il Gun. I hear it'll give the velocity with heavyweight bullets, but with reduced pressures, altho I don't quite understand the concept. I thought pressure ='s velocity. Any thoughts?jd45
