James1984 Posted June 20, 2016 Report Share Posted June 20, 2016 Hello, i have just bought my girst shotgun for a bit of clay shooting and have been searching the forum to see what chokes people seem to start with. however it seems that everyone says 1/4, 1/2, 3/4 etc amd my chokes are Full, imp modified, modified, imp cylinder and cylinder. Can anyone please tell me how the two names compare? At the place i shoot (jolly sailors pub if any of you know it) there is varied traps and some are pretty far away yet some close, my shotgun came fitted with full and modified.

Houseplant Posted June 20, 2016 Report Share Posted June 20, 2016 I put this together for my own reference, it's only a rough guide and you can probably ignore the steel columns. Quote Link to comment Share on other sites More sharing options...

Guest cookoff013 Posted June 22, 2016 Report Share Posted June 22, 2016 full is about 35thou? Quote Link to comment Share on other sites More sharing options...
Breastman Posted June 22, 2016 Report Share Posted June 22, 2016 I was always lead to believe that 5 hashes/stars/notches is Cylinder/true bore, and Skeet is between that and 1/4 Quote Link to comment Share on other sites More sharing options...
TIGHTCHOKE Posted June 22, 2016 Report Share Posted June 22, 2016 Hope this simplifies things. C - Cylinder = barrel diameter. IC - Improved Cylinder - 1/4 = 10 thou tighter than barrel diameter. M - Modified - 1/2 = 20 thou tighter than barrel diameter. IM - Improved Modified - 3/4 = 30 thou tighter than barrel diameter. F - Full = 40 thou tighter than barrel diameter.

ChrisAsh Posted June 23, 2016 Report Share Posted June 23, 2016 For many clay shoots just put in skeet / skeet and you will get 99% of clays Before removable chokes came in i would guess most guns with fixed choke were 1/4 and a 1/2 or 1/4 and 3/4 for field use Its easy to become a choke changer at every stand, but most leave whatever they have in and shoot it all the time and if you do the same with Cartridges you know its only you if you miss Quote Link to comment Share on other sites More sharing options...
B25Modelman Posted June 23, 2016 Report Share Posted June 23, 2016 (edited) I think the standard was and still is with European manufacturers of fixed choke guns, 1/4 3/4 & 1/2 Full. Edited June 23, 2016 by B25Modelman Quote Link to comment Share on other sites More sharing options...
figgy Posted June 25, 2016 Report Share Posted June 25, 2016 (edited) Or for everyone you get than steam trains 1/4 of choke is .25 of a mm smaller/tighter so full choke is 1 mm tighter than the bore. Edited June 25, 2016 by figgy Quote Link to comment Share on other sites More sharing options...
