Re: New Deer Rifle - Suggestions
Given that you already own a 270 win, I wonder if it makes sense to just put some effort into improving it a bit, along with some hand loading ? While the one you own is pretty good, it seems like nearly any gun can be improved with some effort.
It might even make sense to work with (pay) someone locally who has solid hand loading experience (and the equipment, various powders, etc.) to build up some loads before making all of the investment yourself. This might cut several months off of the effort.
I agree with the comments above though, perhaps if you are going through the effort of 700 yards, maybe it is worth thinking about 1 000 yards instead ?
