Need some help guys. I have a Sendero in 7mm RM coming soon and I'm trying to get everything together. I'm having a hard time deciding on which bullets to use. It'll be used for paper punching and white tail deer hunting for now. From what I saw on a few charts it looks like energy and velocity didn't change a whole lot from 140's to 175's. But it looked like the 140's dropped less. I would like to try the 180 bergers but I don't think I can stabilize them. Any suggestions on what size and type to use would be appreciated so I can get to ordering.
