Contemplating tweaking one of a couple existing bullet designs with Accurate. Basically looking to end up with a 250-265 grain LFN in a tumble lube format. Primary launch platforms will be Redhawks, a SBH, and an N-frame.
Veral Smith's site says I can get away with a nose length of .45" in front of the case mouth on all of those. No problem - I'm probably looking at something like .41" and under.
My concern is that this stretches us beyond the "book" max COAL of 1.61" and creeps us up to near 1.7".
I am not opposed to the idea of acquiring a Marlin lever gun or one of the Ruger 77/44 bolt actions to shoot my revolver ammo out of, but don't know what length they let you get away with. The classic Keith clone I'm looking at the blueprint of would kick the COAL up to about 1.685", and I have trouble imagining ANY carbine manufacturer with a lick of sense cranking out a gun that wouldn't work with that.
So. . .how long can you go on the carbines before they choke?
