Bummer. Stark evidence of aging
so here's a target shot at 15 yards offhand. all three guns are sighted in at 25. nice and tight groups, 10 rounds each.
And then i ran a target out to 25 yards, and tried again. those nice tight groups no longer exist. my eyesite is the determining factor on group size. theoretically i should shoot groups a little less than twice as big, all other things being equal. the difference... eyesite and glasses that don't allow me to both focus on the sights and the target.
of course, i am not bitching. nope. the fact that i still have the freedom to load a couple of guns into a hard case and go shooting vastly overrides the paltry inconvenience of the signs of incipient dodderism and advanced geezerhood...
