Decided to experiment with my 20 ga. during the off season. Yesterday I bought a Carlson's .568 Longbeard Choke and 2 boxes of Winchester Longbeard 3'' # 6 shot. Shooting a Benelli Nova 24". Anybody here have any experience with this combo? Have not shot any yet but plan to in the near future. I was just wondering how others made out and any opinions good, bad or indifferent. Thank you in advance for any input on the subject.
