Years ago, I was moderately satisfied with my pattern on my Benelli Super Nova but had heard and read good things Sumtoy. When I invited a good friend to go on his first turkey hunt with me I recommended Sumtoy for his Franchi. When the choke arrived we patterned it, and it was AWESOME! It had a super tight round pattern, probably the best I have ever seen. That sold me so I turned around and bought one for my gun. I tried it with various shells and it didn't perform as well as what I had, nor anywhere near what I had seen with my buddy's Franchi. Sumtoy took it back. I would still give them a very favorable review, it just didn't do well on my specific gun.
