I bought a new Franchi Affinity 20 ga a few weeks ago. Been reloading the Big20XL TSS loads with #9's 40 Yard Patterns in the 50 degree type days. Not sure if my patterns are up to par or sub par. I have attached a few. I have used Sumtoy .562, Carlson Long Beard .568, and Hevi Shot Choke .573. Here are my patterns. Any tips would be greatly appreciated. I have a Sumtoy Base on order to put a Vortex sight on it.
Here are last 2 pictures
Mine shoots best with a primos tightwad .570 and an undertaker .582 ported that I hunt with. Good even hunting pattern. My favorite load is the 90/93 with #9's. My gun shoots the 1 7/8 oz of 8's good with the undertaker choke also.
