DUNKS Posted October 14, 2018 Report Share Posted October 14, 2018 Question for a orrible Sunday afternoon. Why are many older "1920s" .410 shotguns chambered at 70mm when there never has been a cartridge of that size? Sorry no prize for the answer.

JohnfromUK Posted October 14, 2018 Report Share Posted October 14, 2018 Complete guess - 2 1/2" cartridge with the roll closure opened (Eley Fourlong is nominally 2 1/2") Quote Link to comment Share on other sites More sharing options...

Stonepark Posted October 14, 2018 Report Share Posted October 14, 2018 Whilst not common in uk, in spain they did do 70mm 410 chambers and cartridges for a while, but fell out of fashion once 76mm became more prevalent. Quote Link to comment Share on other sites More sharing options...

neutron619 Posted October 19, 2018 Report Share Posted October 19, 2018 There was even a 73mm version - 2 7/8" presumably: http://www.cip-bobp.org/homologation/en/tdcc_public?page=3&cartridge_type_id=7 Quote Link to comment Share on other sites More sharing options...
