Hi guys. By now I'm sure that someone has done testing with RL33 powder to quantify it's temperature sensitivity or lack of. I would also like to know if you have found it difficult to get very low ES numbers of say 10 or under. I have a long barreled 300 RUM being built and am planning on going with Retumbo for this long of a barrel but have been reading good things about RL33. I would appreciate hearing your results on RL33 either way.
