So it sounds like I am going to inherit 3 m70 pre 64 that where originally in 30-06. I am going to build 3 identical rifles for my wife and two daughters. My wife s grandfather started to work on them before he died in the 80 s but basically got them taken apart. So my question is I am planning on new barrels but what caliber? We live in Alaska but will be mainly used on moose and caribou, but if they need to shoot a problem bear. I do reload and can load them up and down to make them fit the girls ability.
