As previously reported, I think my rifle's problem is not the rifle at all. I changed to a Burris Mini 4X and got outstanding results. I sighted it at 25, 50, and then 100yds. With just a few adjustments of the scope I was able to touch holes at 100yds. This old (1983) scope is lightweight, short and still clear and concise. Problem Solved!
Next I plan to load some of the 300gr boolits I received from srussel and bikerbeans. I think a little less weight and a bit more velocity will work quite well. My current load is 16.5gr 2400 and the .452" 335gr Cast Performance WFLGC.
Thanks, Dinny
