I have a friend that was very proud to tell me and then later show me all of his guns, I had just met him at the time so it seemed a little bit odd. He was telling me regularly of his prowess in shooting. How he had never used a scope until a couple years ago and would routinely shoot 1000 to 1200 yards with his 308 and 6.5x47. I had already figured out he was a b.s.'er, by the talk of everything he has done, not just shooting. He also mentioned how his on rifle was set up with such and such scope so that all he had to do was turn it to the number on the knob and that was on for that many hundred yards. I reminded him (we are both pilots) of air density changes from sea level to 8000'. I told him that he knew that IF it worked at sea level, that it would NOT work at 8000'. He just gave me a funny look. He told me that if I ever needed him to shoot coyotes for me, that he would shoot them in the eye at 600 yards.
I have a 450 yard range at my house, I invited him to come shoot probably half dozen times or more in the first 6 months after I met him. He lost his job a few months after that and his housing too. Knowing it was the right thing to do, I offered for him to come stay with me (8 months later he is still here and I doubt he will leave unless I force him out). Now, he had my shooting range within 50 feet of the house. He had many excuses before, like my rifles are zeroed at 1000 yards, I can't shoot that close, or my rifles are zeroed at sea level and here (8000'), they won't be even close. Now his excuse was that he had to rezero everything because he had gotten new scopes (junk). The best one was that shooting that close, 450, was too easy and didn't want to waste his time.
Finally one day I had a target set up at 100 yards, he came out with his out of the box FN model 70 in 308, like a 700 Police. It took him a good dozen shots to zero it at 100 yards. I am no expert shot, but I do ok. So, I was ringing the 450 yard 8" plate with one of my coyote rifles, estimating hold over. He set up to shoot and missed a much larger piece of steel several times.
After the 3rd time shooting with me, he never shot at my range again. But, he did buy a membership at a private range about 40 minutes away in the summer and well over an hour in the winter, he has never invited me to shoot with him.
If he had a Creedmore, it would be perfect.
