dougall Posted January 18, 2017 Report Share Posted January 18, 2017 most 410s are fixed and overchoked.would try with most open 1st and move from there...assuming a decent cartridge max 30 yards,ideally slightly less(assuming pigeon/similar).....

Stonepark Posted January 18, 2017 Report Share Posted January 18, 2017 Depending what bore size you have 13 - 15 thou seems to be the maximum that works well with most cartridges. However be aware these generally print a 35 yard pattern between IC and 1/4, unless using subsonics which print more as expected. Tighter choke starts to blow the pattern. The below is a medium speed cartridge of 21g of No7.25 at 35 yards with 12 thou restriction. Quote Link to comment Share on other sites More sharing options...
222mark Posted January 18, 2017 Report Share Posted January 18, 2017 My wingmaster has 8.5 thou of choke in a .405 bore and is an excellent all rounder. 1/4 and 1/2 in my browning seems to be more open but i need to do more patterning.

Walker570 Posted January 18, 2017 Report Share Posted January 18, 2017 (edited) How long is a piece of string question. Yes, take some time and check on a 'plate' as all guns all chokes through different patterns with different make of cartridge. I shoot a 30 inch Yilditz o/u ejector and after a lot of fiddling around have gone back to full and full, permanently. I shoot Fiocchi 8s (UK7s more or less) and if I do my bit birds fall out of the sky out to 40yrds. I shot some Mirage 6s yesterday at Catton Park, along with the Fiocchis and to be honest I could not tell the difference. Out of 18 birds shot I believe I only had two that did not die instantly. I do believe that once you have a cartridge choke combination in a 410 which works, then stick to it, because I have found the calibre/gauge much more finicky about what it will shoot well with. Have now shot three full seasons ..close to 70 days of driven birds, partridge and pheasant, with a 410 and base my judgement on that experience. A much maligned, much misunderstood little cartridge, but great fun to shoot and having interchangeable chokes has made it much more versatile.

gaffertoo Posted January 18, 2017 Author Report Share Posted January 18, 2017 Must admit you guys do know your stuff and a big thank you,being my age the 12g is getting a bit to much and I thought this just may do me ,light to carry and shoot ,ta .lots Quote Link to comment Share on other sites More sharing options...
222mark Posted January 18, 2017 Report Share Posted January 18, 2017 Also owned a huglu which came massively overchoked at 39 and 25 thou. Once opened up by myself to 20 and 16 thou it threw excellent 35 yrd + patterns, as well as much tighter!!! but was over choked below that range Quote Link to comment Share on other sites More sharing options...

Roughly equivalent to 0.070" constriction in a 12 gauge! To the OP: I'm currently contributing to a project which should end up producing "controlled conditions" pattern data for a number of .410 cartridges. So far, I don't think there's a lot of formally-measured data to speak of, but what there is does suggest performance tails off sharply once you get past 0.020" constriction. I'm sure the best overall constriction will come out in the wash, but on what we've got so far, it's looking like 0.017-0.018" is optimum for maximum pattern density and a little less than that (c. 0.015") for quality of pattern with a slight loss of range. If you're a reasonably good shot and you get a gun that fits, your biggest problem with a .410 will probably be restraining yourself on the longer birds. A comfortable .410 with the right cartridge is a joy to shoot as I've been discovering recently, but even with a good cartridge / choke combo is hard to push much past 35-40 yards. You have to be lucky too - lots of shells won't even pattern / kill reliably at 25 because of what you might term "secondary effects", so you need to pattern it with a wide range of cartridges if you want the best from it.

222mark Posted January 19, 2017 Report Share Posted January 19, 2017 People forget that the .410 was never a long range gun. It works best with open chokes below 30yrds. Read some of the articles by Marshall Williams on the subject on the .410 org website, he knows his stuff. Quote Link to comment Share on other sites More sharing options...
