Did some patterning with the 20 this weekend. Chokes I tried were the pure gold .570 , and an old Hastings .566 I bought years ago. First of the pure gold was very erratic with two shots it ranged from 108 to 138 in 10 " circle. The old non ported Hastings with two shots out up 153 and 154. Much more consistent, I did not count the 20 " circle bu it was easy to see the Hastings was much more consistent.
