            The 7.7 type 92 And type 99 rounds had too
             many different loadings to list.  

This Data came from the 1975 edition of JANES infantry weapons. In My
opinion the Worlds leader in the knowledge of weapons.
Energy Tables are not provided I,ll let you folks figure that up..

First the Italian 6,5mm round is the Carcano right? I believe we have "3" 6,5mm rounds and their all different the 6,5 swede, 6.5 JAP and the 6,5 Carcano.  They don't interchange yet all three 6,5mm rounds have good accuracy it seems to be the norm with the 6,5 round.


Since we copied the 30-06 from the 7mm(7x57) round because it had awesome ballastics( accuracy) do you think our 308win/nato was copied from the French MAS 7,5x54? Since both are very close in size and the french round has been around since the 40's it makes me wonder where we got the idea for the 308win. thus 7,62mm nato?  Another round that is close to the 308/7,62 & 7,5mm is the 7,65x53 argentine round too.  Have you ever wondered which round influenced the 308/7,62?

[S.S.]

In the early 1950's (1954 I think) The US military adopted
the 7.62x51. I believe that it was simply a desire to have a
cartridge similar in power to the 30-06 but one that could be used in a shorter action.  The '06 was probably the inspiration..

Also, there were several 6.5's
6.5x50 jap....6.5x54 mannlicher....
6.5x53.5 Daudeteau....6.5x50 rimmed
....the good ol' 6.5x55 Swede....
6.5x58 Vergueiro (Portugal)...
6.5x52 Mannlicher-Carcano....and I am sure I missed a few.
