Re: Base and Ring recommendation
Not sure of the cost of what youre looking for. But for a pack rifle, I prefer 2 peice bases and NF UL rings. This is as light a mounting system you can get and still have pleanty of beef to hold it all together. These will cost you about 240 bucks complete and will save you weight for your "pack rifle".
Many here are afraid of 2 peice. Funny thing is that one peice bases need to be fitted to the action every bit as much as 2 peice bases.
Long range shooting is a process that ends with a result. Once you start to focus on the result (where the shot goes, how big the group is, what your buck will score, what your match score is, what place you are in...) then you loose the capacity to focus on the process.
