Re: Powder selection for RUMS
Thanks Kirby. This is exactly the type of info I was looking for. I have both RL 22 and IMR 7828 on hand. The max load on the IMR website for 225gr 7828 is 92 gr. I believe this is with the 225gr partition, so it may be a little different with the AB. RL 22 should be similar. I'll back off some and chrono test my way up while observing for pressure signs.
