I recently won a new 22LR, got me thinking of trading some things to get another rifle. I'm looking to get something in between a .30-06 and a .375R....or go back to my plan from two years ago and buy either a .45-70 Marlin or a 300RUM

I'm seeing a couple 7mm Rem Mags on the 110 platform at the local shop. What can you tell me about that round? I'm not where I can look into it at the moment, or I would look it up.
