Remember the old joke about the fastest draw in the west?---"wanna see it again?"
I was lucky enough to get to shoot a .300 Remington Ultra Mag at the range one day. The guy shows up with a NIB BDL. He fires a couple of rounds, then his friend does, and then he offers me a shot.
I was all excited because I had just read a couple of articles about the round and the gun, and here I was sitting behind the genuine thing. One of the gunwriters had described the recoil as the most "abrupt" he had experienced.
Well, he was right! It happened so fast I didn't believe it. It wasn't terrible. But, it was quite a few notches above my 7MM I had at the range that day, lemme tell ya!
I've heard that Remington is offering the PSS in 7MM at the moment. I'd get one.
