don't know where else to post this. but, since this the military rifle section and a lot of us are using the open sights (but for how much longer i don't know) my question is about the size of the black bull that you might be using. the size of the black that i'm using is 8 in. called the 100 yd. small bore rifle target. it's a little too small for my eyes (70 years old) i used to use the 100 yd. high power rifle target with a 6 in. bull, but eyes do change. so, to my question, does anyone make a target with a 10 in. black?? or, any suggestions for a target that might be eaiser to see. oh, i'm using apeture sights on most of my military rifles, and low power scopes on a couple.
