johnny if that's the case then briley are poor engineers , measurement is precise end of , dose this mean briley do not calibrate choke size to nominal bore size .
People buy snake oil if some tw*t says they need it...James I've no idea where in the UK you'd use extra full for but they are available so I presume there's a use for them, maybe the likes of Dubai or the US.
I'd compare it to a set of screwdrivers, yes you can turn a wood screw with a little electric screwdriver but you'd a lot better off using the right one. Yes you can break skeet with full, but you're better off with skeet/cylinder, don't need to be a shooting god to work that out just plain simple logic.
I'm not sure why there is a difference, but all of them were 1/4 constriction tighter than they should have been. I only checked the output end not the input end for diameter. Very crudely admittedly, got a piece of 18mm dowel and wrapped it in insulation tape untill it was a snug fit in a normal half, wouldn't go in a briley at all, but would just go in a 1/4 briley and very snug. So I now have IC and IC in my sporter of Brileys, 1/2 and 1/2 in normal invector plus in my game gun. Must admit I wasn't't best impressed when I found out.johnny if that's the case then briley are poor engineers , measurement is precise end of , dose this mean briley do not calibrate choke size to nominal bore size .
I started on 3/4 and full got worse 1/2 and 1/2 now on 1/4 and 1/4 . Has anyone got a hacksaw?When you start off 1/4 & 1/2, when you're good 1/2 & 3/4, the best tend to use 3/4 & Full, see the pattern ?
I told you soI've just got another pair of Briley chokes to check, this time a Cylinder and another Skeet. These are the results of my micrometer checks of the internal choke diameters. These chokes are S2 for an 18.7mm barrel (.736") or as Briley USA call it .735" and a manufacturing tolerance of +/- .001".
Cylinder - .735" - correct.
Skeet - .735" - incorrect too open, should be .730".
Skeet - .727" - incorrect too tight, should be .730"
Improved Cylinder - .718" - incorrect too tight should be .725"
According to Briley the chokes are mismarked!
I agree that what is stamped on the choke may have no relevance with the pattern actually thrown and that's cartridge dependent. However, when you buy the choke based upon the constriction measurement rather than the name you at least expect that to be right.
