night owl Posted February 9, 2010 Report Share Posted February 9, 2010 I have a old browning medalist and thinking about cutting the barrels down to 24 or 26 inches so there will be no choke in the barrels at all .what im looking for is maximum spread of a 28 gram no 9 shot at a range no more then 20 yards .looking for a 4 pellet hit rate this will then be used for woodcock morning flights next season .the birds are fast and very low light levels and never more then 20 yards away so need a big spread pattern for snap shots has any one tried this before or where can i get info from concerning shot patterns of different cartridges through different chokes before i start have looked at specialist guns for this but the barrels are rifled so the spread pattern is spread out faster over a shorter range then smooth bore guns but i can not get one on my sgc can get one on fac but that would mean i would not be able to hunt with it any suggestions welcome cheers Quote Link to comment Share on other sites More sharing options...
seeker Posted February 9, 2010 Report Share Posted February 9, 2010 Sounds pretty much what a skeet gun does ... ? Also if you reload try a spreader wad - they may open up the pattern a bit. Quote Link to comment Share on other sites More sharing options...

Dave66 Posted February 9, 2010 Report Share Posted February 9, 2010 I have an old book, "The art of shooting" by Charles Lancaster dated 1954, it has some very good charts on boring vs patterns. I will photocopy a couple of pages at work tomorrow an post them up, you may be able to work it out, smallest shot it quotes is sevens, True cylinder, 7/8 oz of 7,s 30" circle at 40yds = 119 pellets, at 20 yds the pattern wont have opened up as much so the pellet count should be higher. At 30 yds it quotes a 60% pellet count for true cylinder A lot of older English game guns had very open chokes Cheers Dave Quote Link to comment Share on other sites More sharing options...
Dave66 Posted February 9, 2010 Report Share Posted February 9, 2010 Probably better to bore the chokes out, you may end up loosening the rib and have to get it soldered Cheers Dave Quote Link to comment Share on other sites More sharing options...

hookbones Posted February 10, 2010 Report Share Posted February 10, 2010 some forces get prickly about cutting down shotguns regardless of it being over 24", insisting on it being done by a sec 5-5.2 dealer if at all so be careful . Quote Link to comment Share on other sites More sharing options...
night owl Posted February 10, 2010 Author Report Share Posted February 10, 2010 cheers hook bones for the heads up have checked with local force and all is ok as long as i hand in the off cut of barrel as it is classed as a pressure bearing part Quote Link to comment Share on other sites More sharing options...
