I appreciate the comments. I didn't look all that closely at the latch and shelf, I'l check that out.
As far as shooting skills, I'm probably at least average. I can consistantly shoot 1" groups with my Savage .243. The only other gun that I've ever had that shot this poorly was a ruger gp100, and, as I understand, that is very unusual.
I don't think that I mentioned in the initial post, but I did try 2 scopes. I tranferred that one from my .357, which was shooting fine, but that didn't help the 44 mag.
Also, there were no keyholes. The shots were just off in semmingly all directions by a few inches. I shot approx. 40 jhp loads and half that many cast. I did clean with hoppes, followed by dry patch after every couple rounds, also tried to not get the barrel too hot.
Again, thanks for all suggestions.
