More of an open-ended question ... Published loads for the .284 Winchester are limited to the lower pressure of the SAAMI specs, derived at a time when the cartridge was primarily for the Winchester Models 100 and 88. In a bolt rifle there seem to be no reasons for that limitation. Given the new propellents we have today, is there a source for higher pressure loads which could produce higher velocities? I realize the .284 is and always will be quite niche, but I'm looking for the best hunting loads possible today. Thanks for any help.
