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.
Thank you sir. Looks like you got some good velocity. Has it proven temp stable? Seems to be conflicting data on that subject.
