i looked in my cabinet and i realized that i dont own one screw in choke gun at all. unless you want to call a cutts or a m59 winchoke one!
my guns are of an age of 'switch bbls' to change chokes. but...the advantage of a fixed choke is, you never leave the wrong one in only to find out 1/2 way thru a world championship where youre already down 10 birds. ;>
the flaw was first realized with cutts compensators in the 40's. guys would go into the field or blinds forgetting their chokes. matter of fact, it was such a problem that polychoke challenged the market with their dial-a-duck choke and did well. cutts then came out with the adjustochoke screwed into the compensator. they got dubbed 'the pickle' for that... being it was overall as big as a deli kosher. lot of people forget the idea for choke changing was to be like a fisherman having a tackle box. you went with a variety to try based on success or failure in the blind or field. but it spilled over into clay sports and here we are with endless choices, experiencing the same issues our fore-fathers had. wrong choke, choke left in the truck, gambling on picking the right choke, shooting w/o a choke ruining threaded bbls, you name it. history is repeated. I learned it was best to just stick with a fixed choke....and still do. sometimes old is ok.
Total lack of concentration will cause this phenomenon and is never the fault of the equipment but sounds like a great excuse for poor performance. I have attended many World National and US Open events along with multiple State and Regional events and haven’t experienced the issue you have described.
Ithaca/skb 20 ga skeet ....26 inch bbls ....just recreational and a killer woodcock gun over my setters
Have a Winchester model 12 two barrels set WS1 and WS2 choked most of the time I used the WS2. Sgoose
I do, a Winchester 101 20 ga choked skeet and skeet, and a std wt Rem 1100 choked skeet. I prefer fixed chokes if they match the game you are shooting. I'm not sure if anyone is making fixed choke barrels anymore. One caveat, you need to mic the barrel if possible.
