[QUOTE="benchracer, post: 1080929, member: 22069"] Retumbo is a closer alternative than RL-33. I know from some work I have done with .264 Win Mag, using Retumbo and RL-33, that QL has VERY inaccurate load density predictions with RL-33. QL shows RL-33 as taking up less case volume than Retumbo, when it is in fact much coarser grained and takes up considerably more case volume than QL predicts. I did find QL predictions for velocity and powder charge with RL-33 to be pretty accurate. When trying to decide if you can get enough of it in the case to make it work, however, don't trust the predicted load density using this powder. [/QUOTE]
