Re: How do you determine a "Good Shot" ?
I nominate Jeff Cooper's <span style="font-style: italic">Rifle Bounce.</span>
"The test is conducted on steel Pepper Poppers placed at 100, 200 and 300 meters from the firing line. Three firing points are specified, three paces apart, and the shooter attempts to hit each target from a different firing point. The shooter starts outside the first firing point with his rifle at "Ready" and carrying six cartridges. On signal he leaps into the first firing point, knocks the 100-meter target down, bounces to the second firing point and takes down the 200-meter target, and then bounces to the third firing point and engages the 300-meter target. He is allowed six shots only, and if he does not take down all three targets with six rounds he has no score. If he does knock down the three his score is his time in seconds. An elapsed time of 30 seconds is good. Twenty seconds is excellent.
If the Rifle Bounce is used as a contest, shooting is entirely free-style in accordance with the principles of practical shooting competition. If it is used as an evaluation of rifle skill, the 100-meter target must be taken standing erect, the second target from kneeling, squatting or sitting, and the third target from prone. A shooting sling is permissible, but a bipod is not. As a point of caution it should be noted that a Pepper Popper will not be knocked down by a low hit if it is properly calibrated, thus a clang does not necessarily signify a valid hit.
If you regard yourself as a good rifle shot, I suggest you give this one a try. The world's record was held by Russ Showers at 18 seconds for quite a long time, but this has now been lowered to about 15. If you can produce a 25 on demand, you can join the club."

I was at Thunder Ranch once - back when it was still in Texas - with Russ as one of the instructors. I can testify that he is indeed a "good shot". I hadn't heard the story above at the time. We had been cautioned to carry a firearm when we were running on the ranch because of feral hogs, and I encountered Russ one day while I was out running carrying a Marlin 1894S. He stopped me to see what I was carrying. Nice guy, as well as an excellent shot with both rifle and pistol.
