Carlson makes the best chokes in my opinion.. Cremators work and pattern great.
I use this brand of choke for hunting, sporting Clay's, Skeet & Trap.. never had an issue.
These chokes fit just the gun just as they were intended to. The pattern from my Winchester SXP with the Cremator Chokes and Kent Fast Steel 2.0 4 shot 1.125 oz loads was exactly what I was looking for.
I am sure, with the extra 1/4 inch length & non-porting, over other extended tubes, the velocity and pattern performance will improve. Have not had the opportunity verify with chronograph or on paper yet, but will report back later with results.
