Hi.
Didn’t the Japanese use the 6.8x51 in WWII?
5.56mm”

U defer to Chainmail. Your posts are informative.
The Japanese used the 6.5X50 for their Type 38 rifles and they had a 139 grain Spitzer bullet that launched at 2,500 feet per second. A bit of an antique at the start of WWII but deadly and had the added benefit of having very little smoke/muzzle flash from those long-barreled rifles. It featured low recoil and deadly terminal effects. Several other nations used this weapon and caliber for decades.
The next most famous (and well thought of) 6.5 caliber is the 6.5X55 Swedish which is still prized for its gilt-edge accuracy but it is also an antique with a 140 grain bullet and a 2,400 FPS muzzle velocity.
The new army 6.5 really ramps up muzzle velocity to 3,000 FPS plus, so it really does outpace all the previous 6.5mm military calibers.
A little closer if the 6.5 Creedmoor with a case length of 48.7 mm and a muzzle velocity of 3,020 FPS and a reputation for excellent long-range accuracy. The 6.5 Grendel was considered for a while but it is a lighter bullet/shorter range round ("6.5 X 39").
Hi.
I read the thread (my bad) and didn’t see if the weapon had a lug/mount for a bayonet.
