Looking into things i see you can get a .460 S&W which will shoot the .454 and .45 colt. is that an intuitive choice over a gun which comes in the .454 which would only shoot the .454 and .45colt? i like the idea of having 3 calibers in one gun vs one that only shoots 2 but it seems like more people have the .454 casull then the .460 S&W. any reasons? Thanks.
