Craig, you made me do it! I counted the pellets and there are 178 strikes in the 30" circle. A 1 1/4 load of 5's normally has about 213 pellets. When I bought these I contacted RST and they confirmed they use hard shot, so going with the 178/213 strikes it comes out to be an 84% pattern at 40 yards. That's pretty good performance out of a modified choke! Maybe RST will read this and send me another flat.
