henry d Posted February 8, 2009 Report Share Posted February 8, 2009 It will be a tad "looser" than 1/4 and a bit tighter than Cylinder Quote Link to comment Share on other sites More sharing options...

casts_by_fly Posted February 9, 2009 Report Share Posted February 9, 2009 reed, Everything I have says that IC and 1/4 are the same. Both are 0.010" constriction. Cylinder is 0, Skeet1 is 0.005", IC- 0.010", Skt2- 0.015", etc. The fractional chokes are 0, 0.010", 0.020", 0.030". That makes 1/4 = IC, 1/2 = mod, 1/1 = full. 3/4 choke would be light full or Imod, depending on how you call it. Thanks, Rick Quote Link to comment Share on other sites More sharing options...
CharlieT Posted February 9, 2009 Report Share Posted February 9, 2009 Improved cylinder is 5 thou, 1/4 is 10 thou. The problem is that American choke sizing is different to English and the Yanks use the term Improved cylinder to mean 10 thou. English choke sizing is..... cylinder none IC 5 thou 1/4 10 thou 1/2 20 thou 3/4 30 thou Full 40 thou Quote Link to comment Share on other sites More sharing options...
casts_by_fly Posted February 9, 2009 Report Share Posted February 9, 2009 ah, well that would be the difference then. I'll have to watch that on fixed choke english guns. 1/2 and 3/4 in a fixed choke gun will be mod/full to me. So really what I want is either IC:1/2 or 1/4:1/2. So I guess the question here then is does reed's IC mean american or english? I'm going to go with American since it is a winchester. Guess the only way to really know is to put a caliper on it.

Peter De La Mare Posted February 10, 2009 Report Share Posted February 10, 2009 Quick one. I have a winchester which only has one choke! Anyways, it says "improved cylinder" is that the same as 1/4? I shoot ok with it, im just wondering Could be the American 'Skeet' choke. There's a table halfway down this page that lists them all as the 'merkins have them. http://www.wildfowlmag.com/tips_strategies/shotgun_062304/ Quote Link to comment Share on other sites More sharing options...
