Good choke - Jebs Choke Tubes High Voltage Waterfowl Black Nitride 12 Gauge Choke Tube

I bought this specifically to shoot Apex TSS, #2 shot, 2 1/2oz for predator hunting. I got a piece of 48-in x 48-in cardboard and patterned it at 70 yards, with EOTech, rangefinder, and stabilized rest. There should be 135 pellets in #2, 2 1/2 oz of TSS. 100 of those hit with this .690 choke. I also bought the same choke in a .685 constriction and it put 121 pellets on the cardboard and in a tighter pattern so I kept that one.
