I think you are doing the right thing by starting with another rifle. Putting your grandfather's Mod.70 up for another time. It could even be a pre-64 Mod 70 which would make even more valuable over the sentimental aspect of it. Don't mod it just to save a few bucks. I still suggest like I did in one of your other threads, look at one of the cheaper bolt guns in 223. Getting used to pulling the trigger for cents per round over dollars per round will get you more experience. Just from reading most of your posts on here it seems like you need that more than anything. Start hitting steel plates regularly at 3-4-500 yards will get you a great start at hitting plates at 6-8-1000 yards with whatever big bore you end up with. We all had to start somewhere.
And when you do start reloading, which you will, that will get addicting.......
