To each his own, but I have always heard about
more people shooting at a 10 inch circle than any other size. I believe the circle on a Primos target is 10 inches, and I know Nitro Ray uses that as well. I shot one of our guns today and at 40 yards I had 128 in the 10 inch circle, with 62 in the turkey head and neck with one load, and 115 and 58 with another load. This is the best any of our guns has done so far.
