I just got a 50 percent off cert for thunderbeast and I am trying to decide which can to get. I have an idea I want to build a 300 PRC so primarily that is what the can would be sitting on in most cases but I also may but it on some other short action cartridges. I want one of the magnus line suppressors. Currently thinking of the magnus rr or the magnus-s rr. What are some pros and cons of each. Weight is not really a factor.
