I bought a new 452 last year, and it out-shot my early 455 hands-down. My 455 IS coming around, finally, but the 452 I bought in 2015 was a shooter straight out of the box. All I did was mount a scope on it and shoot.
Some of the early 455s had some problems with the barrel crowns, I'm told. Mine didn't seem to have any, but it never shot as well as I thought it should. It is, now, though, coming around, as I said.
My 452 is shooting the way I thought the 455 should, straight up, right out of the box.
I'm keeping both rifles, I really like them a lot, but I'm more fond of the 452.
