I've been reading a lot of places that guys are using RL-25 with 105's and 107's as it tend to be easier on the throat once the speeds get up around 3K. I found a couple loads online and have a call in to Alliant. I was just curious if anyone here has run this combination. Most say that the starting load for RL-25 should be near book max for RL 22, but I'm not sure I want to start there. Anyone have any experience?
