AT 50 yds this thing shoots 12" left, up and down is fine. I've bought this gun new in about 1974 and hunted with it for all my teenage years, so I know it use to shoot fine. It's been in the safe for the last 20 yrs or so. But now with casting, and wanting to remember the old times, I got it out and ran some store bought ammo through it, and at 100 yrds I could not even see where the bullit hit. So up to the 50yder and at least I could find the hole.So into the gun room I go, complete disassembly and cleaning, thought maybe some old hard gummy oil and stuff was under the barrel. Back out and still 12" off. Ok now I start tapping the frount sight over, gets better, alittle more, better yet, now the frount sight is about to fall out of the dovetail, thats not good. So I stopped and came here.
Questions
Tapping with a hammer and brass punch is not the most precision way of doing this, so what is?
What else can it be? Using a laser beam the barrel seems straight,same with the stock. The crown looks OK, but I think it would have to be really bad to be this far off.
Any ideas, suggestion?
Thanks Nick
