My 455 is a great shooter in 22lr and 17hmr. Doesn't like Vmax ammo for some reason as much as the 20g stuff. Still shoots 1/2 inch at 50 with Vmax though vs game points are tiny groups.
Not a single problem with it and have not read about any problems with them. Enlighten me as to the problems
Many said 452 is more accurate but mine shot as good as either 452 I have shot beside and shot as good as a cooper JSR 22lr with a factory 22lr barrel and only a yo Dave trigger job
