tungsten Posted September 15, 2009 Report Share Posted September 15, 2009 Just as a pointless excersize i decided to measure the chokes on my Hastan Auto with my choke gauge and was suprised by the results. Mod = 1/2 on the gauge and so did Imp Cylinder. Imp Mod = 3/4 Cylinder = 1/4 Full = Full so tried it on my Beretta Chokes with similar descrepencies. (although the 1/2 (green) did = 1/2 on the gauge) But on my fixed choke Lamber both 1/4 and 1/2 were correct on the gauge. So I assume that multi chokes cannot be measured with a choke gauge? becuase they are engineered differently?? or is it becuase there are variations in direct comparison between numbered choke sizes and worded sizes, dots or stars Quote Link to comment Share on other sites More sharing options...
Baldrick Posted September 15, 2009 Report Share Posted September 15, 2009 Multi-choke gauges won't tell you a thing, sadly, assuming it is the standard brass plug-type gauge that most RFDs sell. Choke is the degree of constriction imposed, and it is not a finite measurement of diameter. You need a gunsmith's bore gauge to properly calculate choking.

mikee Posted September 15, 2009 Report Share Posted September 15, 2009 here is a table of choke restrictions which might be of use, scroll down its near the bottom of the page http://www.shotgunworld.com/amm.html mikee Quote Link to comment Share on other sites More sharing options...
henry d Posted September 17, 2009 Report Share Posted September 17, 2009 Remember that it is what your gun patterns not the choke that you screw in that matters. try your chokes and cartridge combo`s on a pattern plate/paper sack to see what the Bobby Moore is Quote Link to comment Share on other sites More sharing options...
