I've got an RSM in 458Lott only because I liked the wood on it. I've been lucky with my RSM's in that they all have good trigger pulls @ 3#, give or take a 1/4# or so. The Lott is definitely a bit more horsepower than a 458WinMag. I got a thicker recoil pad installed on it and put a bit of weight both fore and aft to insure a bit of balance. Using irons and factory ammo, I got 1 3/4", 3 shot groups when I was concentrating on loving the recoil. This was at 100 yds. When I wasn't concentrating on how much I really love recoil, I got 2 1/2" groups or worse. The rifle is glassed at the recoil points and relieved at the tang. The claw was smoothed out and all the small burs taken out. It'll feed flawlessly. As far as shooting, it literally is a BLAST. Of course, there are bigger guns and cartridges out there but after learning to handle it, it can be fun.
