Took the 12 ga out this morning before work and went out to the back side of the area, Setup four 3ft by 3ft targets. Stepped off 35 yrds. First shot was with the extra full setting. 130 some pellets in a 12 in circle. Me thinks I have another turkey gun. Next was the full setting. 116 in the circle at this setting. Mod was next 98 in the circle this time. full open/cyl bore 66 in the circle this time. This choke really works, Makes me feel better about spending the money for it ...well actually the GF paid for it as a late Birthday present. Next I want to see how it shoots slugs. I was shooting remington long range 6 shot for testing. I might have gotten a better result from the full open if I was using a smaller shot size but it gives me a pretty good idea how its going to dso in the field.
