Good Morning All,
I've been doing some searching on the 'net for those who have been crazy enough to wildcat the 7.62x54R round. I've seen plenty of info about taking the cartridge up to 9.3+mm bore diameter, but want to know if anyone has any info about rebarreling and chambering for .22 (5.56x54R) or maybe even .17 (4.3x54R).
It seems that with the abundance of match-grade .22 barrels available, a proper improvement on the crap x54R neck angle and a serious .22 bullet would produce some screaming velocities.
Perhaps the brass can be formed over a mandrel on the lathe to get it to neck down that far? Some throat diameters on the original 7.62x54R are .314 or above! I've got a long way to go to get a .22 to seat.
Discussion is officially open....
