The M77 RSM is the one I had been looking at. I would like to get a little info from someone that has used one first hand to see what they like and don't like about it. Also a little info on what kind of accuracy they have been able to get out of it using factory loads vs custom loads. Also some people say that a 458 is good to hunt any game there is and some say it isn't. How much more could possibly be needed considering the choice of bullets you can load in it?
