I have an old Model 70 in 30-06. It was my first ever gun that I bought about 12 years ago. However, 2 years ago when I was on deployment, my buddy had his basement flood where his safe was and now the barrel is pitted and it can't hit the broad side of a barn now (I shot another one of my rifles that same day to be sure it wasn't operator error and rebuild my confidence). I was going to sell it off, but I really wouldn't get crap out of it. So my next option would be to keep it and upgrade it. After finding this site, I am wanting to upgrade to a larger caliber long range rifle now. What are my options for caliber? Could I turn it into a 338 lapua? I want to keep it for sentimental reasons, but am I just wasting my time and it would be cheaper to just buy a custom rifle from scratch? Also, I am in Eastern NC and when I google gunsmith it gives me pawn shops and local gun stores so there really isn't a gunsmith around here either so I would have to send the gun away for everything. Price is also a consideration as I want to keep it as cheap as possible, obviously I know I won't be getting it for around $500 Thanks for the help!
