I have got one of the origonal 6.5mm magnum calibers the 6.5x68 it was designed in the 1930's mine will push 140 grain bullets at 3100 fps with only 65 grains of old H4831 that is only 5 grains more than a 270 with 130 grain bullets but the 6.5 bullets have a better B.C.
I have a reamer and go gauge that I may hire out for a fee Depends on gunsmith
