With the advent of long cylinder revolvers that are purposely designed to accept .410 shot shells, what the criteria for a gun barrel to be considered rifled?
Obviously the purpose of rifling is to spin stabilize a projectile. Does rifling have to meet any criteria for depth, number of lands and grooves or helicality?
It occurred to me that a polygonally rifled barrel, with a suitably high number of sides and a extremely low twist rate would have the effect of being virtually a smooth bore.
So should I put that .729 caliber 4" cylinder six shooter with the 1 in 5280 ft twist double decigonal rifling into production? And do think they'd notice if it came threaded for an a polychoke?
