I am planning to load some Berger 210 VLDs (UN-coated) for a 300 RUM and try them out this weekend. I have some Retumbo laying around that I have been using for 180 NBTs and NABs. Anyone got a load to reccomend? If you have found a different powder works better with the heavier bullets let me know. Thanks

Sorry, but I have no advice other than to first try the powder that is working so far and work up slowly. I have heard of good results with RL25.

What I would appreciate from you is if you should test the Bergers in any sort of expansion medium or animals, please post your results here. Walt Berger himself told me the 210 would be outstanding even on moose. I would prefer as many opinions based on experience as possible, so if you should develop one.......

Try 90 gr Retumbo or RL25 and work up!

Thanks pop, I will start with 90 and post my results. I have a chrony.
