Hi, I have a 452 American, Left Hand model, that is pretty nice. I'm not in love with it, it's not as nice to shoot (trigger), nor is it as accurate as my old Remington 513T Matchmaster. It is nice enough, but me and scopes don't get along the best. Knowing that, and the fact that the 452 American can only be scoped, I should have foregone the 452 American altogether. I now want THE BEST iron sighted CZ, 22 rifle. So, 452 Ultra Lux? 452 Trainer? What others should I consider? This will be used for informal competition, out to 100 yd (but mostly 50 yd) and for my own (accurate) shooting pleasure. I love the small groups that my 513 produces, but I just want another 22 bolt gun. It might as well be a CZ. Thanks.
