It's not a particularly hard target at 20 yds to be sure. The 3/8" @ 20 yds is definitely the easiest one, I think the originator of the target suggested 20-25 yds. for that one. I'm no wizard with a rifle and I got most of them.Interesting... 3/8" tacks at 20 yards is 15/8" tacks at 100 yards is a tad under 2 MOA. I can see how much fun that game is!
The 50 yd version uses 1/2 inch circles, the 100 yd one is 1 inch circles. I think that'll be a different critter altogether.
I might try and cook up a 20 yd pistol target along the same lines.. 1" circles would be a good place to start. If I put them close enough together I should get at least a few
With the weather improving steadily, I'm going to make some 50 and 100 yd attempts with the rifle soon. I'll be lucky to get 50% at 50 and 25% at 100.
Get shooting, hombres! Put up some pics of yours!
