Thread: 7x57 Ackley

I think that you should do it. The 7mil is a great cartridge and just at the right spot for capacity relative to bore. If Ackleyising a 257 Roberts works so well then AI'ing the 7x57 will be a winner for sure. 270 performance with less powder, noise, recoil. A full case whereas loaded 270 cases always sound like salt and pepper shakers, so should be very accurate.
I would go for a medium length Mauser action. As Huskey 1600 writes above, a Brno or Huskey would be great but a donor Parkerhale Safari with a buggered barrel would make a very handy hunting rifle and would keep the costs sensible. PH $300ish, Shilen barrel from Gunworks $690
