I have been shooting for over 60 years now. I can recall lugging a pair of fixed choke Remmie 1100's, complete with a spare barrel around Sporting shoots, in the early 1970's. That gave me Full, 1/2 and Skeet choke options. Then along came Beretta with a drop in choke system........manner from heaven ! I could now spend most of my time between stands, changing chokes
A short while later Winchester produced their 'Winchoke' system. How good was that ? Now I could have differing chokes in ONE gun, it took longer to get between stands because I had to make TWO choices.
Eventually after many gun changes, I got a gun that came with 2 x 1/4 chokes and a few others too. I shot some Skeet and had put in the 2 x 1/4 chokes. My next outing, like Ben, I thought I had put 1/4 & 1/2 in the gun. I did a 100 bird Comp at Hodnet, which can be a 'testing' ground. I ended up in a shoot off for second place, nerves beat me and I finished third. It was only after I got home and was cleaning my gun, I realised I still had the 2 x 1/4 chokes in. That was 36 years ago. To this day I still shoot 1/4 & 1/4 chokes for all my clay shooting ( I have a fixed choke trap gun for trap disciplines). My competition days are well over now and I just shoot for fun. However, I still like to keep score of my performance on the day, just for my own amusement. I still manage to hit 75% + although I do admit to carrying a box of Express World Cups 6 1/2's in my range bag, 'just in case'. I bought 250 World Cups around 15 years ago, I still have 125 of them
If tight chokes give YOU confidence , then use them, BUT, do not be afraid to try more open chokes, possibly as an experiment. You could be pleasantly surprised.
My current gun, Classic Doubles, 30" multi choked, ported barrels, with 2 x 1/4 Briley extended chokes. Weight, exactly 8lbs.
