In most bolt actions I've seen people using a sleeve to cover a hole in the barrel. This is functional but it always leaves a large amount of dead space between the hole and valve opening point. It also typically limits one to only using spherical ammo (because the hole gets too big for much else). This is why I want to make a floating barrel mechanism. I can insert any kind of ammo into the rear of the barrel and then push it back far enough to eliminate almost all dead space.
The one issue with this however, is that I foresee a lot of torquing on the barrel. When my ideal barrel is thin-walled copper tube I can see this being problematic. In the diagram I quickly made, the purple arrows indicate the loading I'd expect to see when firing. The bolt would latch into the body to lock in place and take most of the load. But because of the offset, the barrel would have to resist some twisting load as well and this is where I see an issue arising.
I'm wondering if anyone knows of any good ways to lock a bolt action floating barrel in place? Thanks!!!
