"30 yard - Outstanding Pattern. Factory Federal 10ga - 3 1/2" - OO Buck ( 18 pellets ) - Copper plated / Buffered. Fired from a Rem. SP-10 24" barrel - X-Full choke ( Deer ) 30 yards = 14 inch pattern - 17 pellets - with 1 flyer.... ( 20 inch with flyer ) Extremely tight pattern 50 yards = 24 inch pattern - 13 pellets - ( approx 35 inch with flyers ) Probably extreme MAX range for this load. I did not expect these kind of patterns with OO Buck. I called and spoke to C-n-C and asked which choke I should start with. I've never had a purpose to use OO Buck until now. This is the one they suggested to try. I was told that if it doesn't work for me, let them know & they would exchange for something different. What did I have to lose ? I think this choke is Outstanding ! I'm not sending it back, the coyotes are not going to be happy..... Yes ..... I recommend this product." - James S.

"Tried this choke with Winchester Double X, 2oz, 1300fps #4 lead & also " MY Load " turkey loads. It's a 1 5/8oz, #4 lead, Copper Plated, published load, using Herco Powder..... Best pattern I've seen. Absolutely Outstanding ! 30" patterns at 50 yards. I have a Jeb's Headhunter .680 & Trulock Turkey .700 that I tested with both loads.... This Comp-n-Choke tube blows them away ! It's not even a turkey choke, Its made for Buckshot !!" - James S.
