[QUOTE="Engineering101, post: 776571, member: 63138"] [FONT=Verdana][SIZE=2]There sure isn’t much data out there on RL-33. I worked up some loads with it in a long throated 7mm WSM and got impressive results and the burn rate was nominal. I then put it in my 300 RUM and the burn rate jumped way up. What I thought would be a minimum starting load turned out to be a max load that happened to shoot very well. Load development pretty well done but… I missed big time on the starting load so do be careful. I did see some data from Alliant for Lapua 338s using 300 grain MKs which showed 2,748 fps and 64,530 psi with 97.5 grains RL-33.[/SIZE][/FONT] [/QUOTE]
