Let's see.....a 3-4 inch group average from 20 yds......
A ping pong ball is 1 & 1/2 inches in dia, a baseball is 2 & 7/8's inches in dia, and a softball is 4.5 inches in dia.
I guess if you shoot a ping pong ball sized group on Monday, then a softball sized group on Wednesday, then a baseball sized group on Friday, you would have averaged a baseball sized group.
The group I posted on the 1st page of this thread measured 2 inches....from 25 yds. No, I can't do that every time...but on average....from 20 yds....I bet there's more guys capable of that than you think.
And with a compound, with sights....sheeeeeit. Ray Charles could do that with a compound.
