Just received my RL-33 this morning. I'm shooting Berger 300gr OTM with Fed 215 primers. I had asked for Alliants reloading guide but unfortunately they did not send it with my powder so ill try there website again to find a good starting point. Ill keep everyone posted on my load development.
I can't find it offhand, but I recall reading a thread started by Kirby Allen (fiftydriver) testing drops in RL33 at various temperatures with consistent results. If I find it I'll post a link (or someone pick up my slack)Thank you sir. Looks like you got some good velocity. Has it proven temp stable? Seems to be conflicting data on that subject.
