Reloader 33 Powder

Guest · Jun 17, 2013

I just purchased some RL-33 for the 300 RUM. Anyone have some results or Load Data to share with this combo using 200 AB? I will be using Remington Cases with CCI-250 and Fed 215 primers. May even give Remington 9.5 Mag Primers a try too.

Thanks,
Don

Put some loads together yesterday. I'm starting with 93.0 then 95.0, 97.0, 99.0 and 101.0. Loaded one round each with Fed 215 and Remington 9.5 M primers, checking for pressure signs, slowly working up. Testing for initial velocity with 200 AB.

Now to get to the range with the Chrony. :mrgreen:
