You can always unscrew the muzzle brake and replace with threaded cap.

A good brake does more than reduce the recoil it make the rifle kind of "just sit there", much more controllable. However, if you are going to be using a rifle without a scope probably some of the adantage of a good brake will be lost.

If you leave out of the equation the "what you want" then the 450/460 Vs 458 Lott will depend on how you use the rifle and how much you like to play with loads and so on.

For example, a 378 or 460 with a good brake is a rifle that you can rest across a sandbag on the car bonnet or the external mirror on the vehichle and use it as you would a 300 mag and unlike the 458 Lott the big ones have the trajectory.

If 2300 with 500 grainers is what you are looking for an analogy might be that the 458 Lott is the 4 cyclinder car and the 450/460 are the big V8 and even if you are in wrong gear it does not matter. To get the 2300 the loading parameters are just so much wider with the 450 or 460 which in turn makes acccuracy an easier thing to achieve. But if the rifle is not going to be scoped then some of those pluses are lost.
