[QUOTE="Jokostel, post: 1166269, member: 39379"] Just want to bounce an idea off of folks.... Right now that new 280 AI build of mine seems to eat several things VERY well.. my standard 140 load does well, however; I built this weapon for 168s and above. Its got a #5 Brux finished @ 26 in + a vias break... and velocities seem to be SPOT on. It seems to be pushing 140s right around 3200 with RL17... and with the 175 ABLR and 60 gr of I7977 it does ~ 2780. These are both running WLRM primers... OAL is 3.330 I was contemplating testing RL33 to gain some advantage thanks to the barrel length. The question is... with the burn rate of that propellant, would I even reach pressure... say at 62-64 grains on a 175ABLR -180 VLD ? My "off-the-cuff" guess was to start at 60 and work up to around 64-65 grains. Does quickload have ANY predictions for this, or am I looking at a waste of time even attempting this? [/QUOTE]
