[QUOTE="Tyler Kemp, post: 405878, member: 6290"] 300 Pegasus Improved (theoretical, 145 grain case capacity) 40" barrel 173 grain GS Custom bullet seated .2" into the case neck. 70k psi max pressure 136.1 grains ADI AR 2218-4064 fps 129.6 grains Vihtavouri N570-4020 fps So according to Quickload it can be done. Would be the edge of pressure assuming calculations are all correct. Also, 40" is a dang long barrel. If you're gonna do that, might as well bump it up to 46". Velocities are well over 4100 fps...or you could reduce loads to just be at 4000 fps. Either way it's not very feasible, but would be a neat project for some short term fame. [/QUOTE]
