Yes.. but the 6,5x55 SE was made to function 110% in a total war scenario..
Straight walls and sharp shoulders are not conductive to perfect feeding and extraction in those conditions.
Although target shooting dont have those constraints put on them
.
Yes around 1893 it seemed important especially with rifles manufactured with large tolerances. Of course you are right the swede has nice shape . Then again the 308 also seems to feed vey well, manages well over 1000 rounds per minute from a single barrelled MG3, one I shot never had a jam... mostly out of ammo though.
SOCOM is using or at least testing the 6.5CM since a few years (not the Swede) however it seems fairly quiet about it.
My guess is the 6.5 CM would be chosen over the Swede if the military would need a replacement.
