If you try www.stalkingdirectory.co.uk you may find some who have experience of it.

There were a few custom (or bespoke as we call them) bolt action rifles made in this calibre about ten years ago.

They were fairly well written up in one of the British shooting magazines.

Hope that hepls!

Seems to be a light recoiling game getter.

It is. My ever so close 7mm X 41mm designed in 1959 and finally built in 1982 is ever so close to it. Great little cartridge.Still have the reamer if you're interested. roger

I would not bother at all with the 280 but go to the factory available 6.8mm Remington SPC. It will do absolutely everything that the 280 will do!

That was supposed to be the caliber for the fn/fal but the 308 won out. POLITICS!
