I have a Win. Pre-64 Model 70, in .270. This rifle was my fathers, and he shot several moose and deer, and a blck bear with this rifle. He passed away 8 years ago, and I now have the gun. Was planning on bringing it to AK this fall on my hunt. The last several years my dad was alive, he had accuracy problems with this rifle. He kept blaming it on bad scopes. Yesterday, my son and I were target shooting with it and our other rifles. The Mod. 70 was throwing them everywhere. Could not get close to even an 8 inch group! I had a new scope on the gun, swapped out scope from my 30.06, that was right on, and the same thing, no accuracy at all.
Trying to figure this out. My father had a gunsmith drill port holes in the end of the barrel about 20 years ago. I think this is when the gun started spraying the shots, and not grouping. Any thoughts on this. I really wanted to bring this gun with me on my hunt this fall, but its not much good if throws them out like this. I don't claim to be the best shot, but with my sporterized 03A3 30.06, I can group the size of a half dollar at 150 yards. Thanks. Knute
