Need data for 7mm RUM+180 VLD+Retumbo
I'm going to load some 180 gr VLD's in my 26" 7mm RUM and the slowest powder I have is Retumbo. I figure I'll try for 3000 fps or maybe 3100 if possible. What would be a decent powder charge to start at and what kind of velocities are you guys getting?
The critters have to win every time, I only have to win once.
