I like to shoot at small, maybe 1”, squares of masking tape no matter the distance. I’d bet a good amount of $ that if you shoot groups at that for a while, and then shoot groups at a 10” circle, you’ll have a lot more arrows within 10” of the tape squares than you’ll have inside that 10” circle. You aren’t shooting at a 10” circle; you’re shooting at THE CENTER of the 10” circle.
