A couple years ago I built one on a pre 64 M70 action, fwt barrel and mcm edge stock. it shoots and handles great. I put up some nosler 280 AI brass and load it with 150 TTSX's @ 3050. It's been a great flat shooting round that hasn't needed the brass trimmed yet.Just like most calibers it's killed well.... My rifle weighs about 7 3/4 scoped which I feel is just right. I'd think twice about a flyweight though....
I have no regreats putting mine together.
