[QUOTE="AZShooter, post: 1240324, member: 5219"] I looked up the original load data Alliant put out on the 7 Rem mag and 175 gr bullets. The max load data was: 7MM rem mag 175 speer sp 75.2 gr RL 33 @ 2909 fps 7MM rem mag 175 speer deepcurl 73.8 gr RL-33 @ 2853 The 7 LRM holds slightly less powder than the 7 STW. Here is what Alliant first published: 7mm stw 175 gr speer deep curl, 84.5 gr RL 33 @ 2946 fps 7mm stw 175 speer hpbt, 85.7 gr RL 33 @ 3033 fps Figure out the case capacity of the 7 LRM in relation to these two cartridges and you should have a starting point. You could always ask Gunwerks. IMO RL-33 may be a bit too slow to get top velocities. Based on a few cartridges I have used RL-33 in I'd say you can fill the case to 100% load density with a drop tube and not show pressure. Don't start loading that way..... just saying it will be filling the case. (it is that way with a 6mm-284 and the 257 weatherby both with heavy for caliber bullets.) [/QUOTE]
