Hi WoodWelder,
It certainly does appear that I am overly generous with the scoring. But you need to understand about scoring plugs. Since I am shooting .177 pellets and someone else might be shooting .22 pellets, how do we make the scoring fair. Obviously, we should score by the hole center - but we can't. We score by the outer edge of the hole. But a .22 and .177 hitting exactly the same center will have two different outside edges. Thus, the scoring plug. Attached below is a link to a site where you can order the plugs. Basically the plug has a metal pin with the same diameter of the caliber of the pellets you are shooting. so if you put it in the hole you are centered in the hole. Higher up it has a flange (or clear ring with an inscribed circle) which has the the approved diameter for the class of target you are shooting. In our case it is a .22 caliber. The actual diameter of the outer rings is 5.66 mm. Yes, it is .1mm larger than the standard for .22, but the pellet diameters vary quite a bit.
A target scored with a plug will give a different score than if you just use the edges of the hole. It also allows you to compare scores from different caliber rifles. In the big 100yd benchrest competitions they typicall score with a .30 caliber plug so shoots can use any caliber that size or smaller.
Get a plug for your caliber and enjoy the scoring process. !
Cheers,
Greg
PS - Just for grins I am attaching an Excel plot of the 20 shots used to score that target at a 5.66mm diameter. One MOA at 30 yds is 7.98mm. Yes, I am a complete Excel nerd.
