Thanks Ranger Z. You are indeed a humble teacher.
As an "I think I figured it out" my Buffalo Classic 45-70 was shooting at the moon instead of the 100 yard target because of the sight that it came with. I did my due diligence to find out that the ladder sight installed was a Smith (an AZ company) sight specifically made for 500 yard plus. Hence the issue. It could be really good one day, maybe black powder on the Big Range.

I located on Numrich an "original" rear sight for this rifle that sits so much lower I think I am good to go. We'll see.
So Maddog when is the next Long Range Match? As always let me know if I can help, especiallly if you sneek in to set up the range at dawn.
Looking forward to the next one.
