I've been trying RL-17 and 180 Gr Barnes TSX but I'm getting lots of pressure way below max (like at my starting load of about 62 grains). I'd like to end up with a accurate load around 3000 fps. I'm thinking a slower powder may be better for this rifle (New Kimber Montana). I also like the idea of a less temperature sensative powder with the Hodgdon powder. Any of you guys using this bullet powder combo? What are you seeing for results?
