Never shot one of those but the 7mm has an "explosive kick". Hold on tight and get a scope with really good eye relief. I have a 375 H&H and it kicks freaking hard but its more of a push than an explosive jolt to your inner body.
This is a very accurate description of the 7mmRM.
Explosive Jolt....I like it!
I've kept mine because one never knows when an 18foot pissed off Grizzly bear will head east and decide to decend upon a loved one.
Hand load it if you can, its a very capable round and Full power loads are rarely needed here in North America. Its one of the flattest shooting 7mm's out there and ammo used to be available at Wally World before the Great Gubbermint Ammo Grab.
