1967spud Posted May 9, 2015 Report Share Posted May 9, 2015 i was using a rifle with a normal barrel threaded at one end pretty much like being threaded for a mod. Any way i was dreaming that i was using this gun for different uses and was able to screw a 6" or so in length short barrel on but had a different twist rate to the main barrel so in i was able to slow the twist rate or quicken it in that added section. I said it was a bit James Bond any way woke up early this morning to do chicks etc and completely forgot about it till now which got me thinking to the feasibility. I can see many down sides to the idea but i did wonder if there had ever been any research or mutterings along the same idea. I know Bartlein do the gain twist which is an old idea revamped but the option to change to final twist to a desired one was what I was wondering. And before anybody says it I am Spud Bond 0067 license to thrill!! Link to comment Share on other sites More sharing options...
MrCetrizine Posted May 9, 2015 Report Share Posted May 9, 2015 The German krumlauf curved barrel thing was an extension. It bolted on the end and had a slight freebore that the bullet had to jump. Link to comment Share on other sites More sharing options...
gbal Posted May 9, 2015 Report Share Posted May 9, 2015 The "Paradox" shotgun/rifle was a proprietary attempt by the bespoke London gunsmith(s-H&H ?) to have a rifle performance from a shotgun barrel-by rifling the last few inches-very careful regulation was needed. I'm no gunsmith,but I'd have thought that indexing/timing the rifling to exactly 'fit' in a continuation of the existing rifling would be extremely difficult on any screw on extension barrel-more a recipe for bullets being badly gouged....and for little gain (is the hoped for flexibility to switch to heavier fast twist needed bullets?) Standard switch barrel of course does it much better,would there be any need to change twist on the hoof? gbal Link to comment Share on other sites More sharing options...
That bald headed Geordie Posted May 9, 2015 Report Share Posted May 9, 2015 Mark. Just dream of sheep like I do. Far less stressful and always a happy ending!!!!! Link to comment Share on other sites More sharing options...
MrCetrizine Posted May 9, 2015 Report Share Posted May 9, 2015 I'm waiting for a smooth bore that has some kind of flux capacitor that spins the bullets to your desired twist rate using science and/or magic. Link to comment Share on other sites More sharing options...
