Was looking at what's out there for cobbling up another cast cartridge with a lengthened neck.
There's a #280473 and a #280642 sitting neglected in the fun box. What a neglected caliber!
So, what if.
A rimmed case with a lengthened neck could be made running 30-30's into a 6.8SPC sizer, trimming to length and fire forming.
Could a 6.8 barrel blank could be chambered by running the reamer in a tad deeper and then cutting the rim? And then cut the neck to the length wanted for the lube grooves to be covered and boolit lengths to be used.
If I had an extra single shot sitting around, yeah, I'd like to try something like that. Meanwhile I'll dream on and enjoy the .25's and .28's.
