25 yards they need to be within 2" no matter the pistol or I"ll look at what I'm, doing wrong or getting rid of the gun. I shoot some pistols out to 50 yards and I want to be able to hit a 50 round ammo box pretty consistently. more than 2-3 fliers and I'm pretty upset.
Oh..Rifles I don't shoot much over 100 yards as I don't have a whole lot of room to get much more safely. Depending on the rifle I will want to have no trouble placing on a 4"x4" square where I want it to be. Except with 22's, I give myself a little more room with most of them.
