Trying to identify ammo.

G'day. I am trying to identify some .270 ammo. It has a head stamp of MMY (possably NNY) on it. It is sold in Australia as HIGHLAND. The stuff I have is 130 grain PSP.
I want to add the bullet details to my Sierra infinity custom bullet data.
Any assistance is appreciated.

Hmmm... I don't know of any "MMY", only "NNY" which would be PRVI PARTIZAN from Serbia... I'd be interested to know who makes their brass.

But according to their websight, http://www.highlandammo.com/ they use standard Sierra Game King soft point boat tail bullets.

130 gr loaded to 2,953 fps
150 gr loaded to 27,56 fps

The 130 gr bullet has:
.436 @ 2800 fps and above
.418 between 2800 and 2200 fps
.402 between 2200 and 1800 fps
.387 @ 1800 fps and below

The 150 gr bullet has:
.483 @ 2800 fps and above
.476 between 2800 and 2200 fps
.462 between 2200 and 1800 fps
.435 @ 1800 fps and below

G'day. It could be NNY . I'll edit the original post to include that possibility. Thanks.
