I just got done checking the data sheets fron Marty and they dont list any loads for Alliant RL7. I'm using a 300 gr Hornady bullet. Can you give me a starting and max load?
You posted a couple of loads in a previous thread of mine but I don't know if they are starting, max or middle of the road?
Thanks in advance,
Jerry
