I've never mounted a scope before so I used one of those laser bore sights, and needless to say after a box of shells my gun was not sighted in, but I think some of that was my fault. Went today and tried to sight in my gun, and had a little more luck, but I ran out of bullets. My gun was at least a foot high and a foot to the right at 100 yards. The high part is what kept throwing me off. Anyway I've been looking at bore sights, and what would be a good one to get. Several years ago I had a gun man who used one that had a graph. Every gun I purchased from him was dead on or just 1-2 clicks off. The laser sights seem to be hit or miss. I've just decided it's time to get my own tools so I can mount my scopes.
