Great choke tube for duck hunting but if you're a dove hunter to I would get an improved cylinder too or I would put the modified choke that came with your shotgun back in for dove because you won't be able to see much of a pattern difference between the two when shooting #6-#8 shot sizes that's just my personal opinion.
Excellent choice in choke tube design and manufacturing. I have purchased and used several other brands and would buy this brand again. I now own 12, 20 gauge Kick's and recommend them highly..
A quick test gave me about 80% of DEAD COYOTE T shot in a 20" circle and 85% of Remington #4 lead buck . Both at 30 yards out of my 20" barrel in a Mossberg 500 Turkey -Tactical, which is plenty tight for a coyote being chased by my hound.
