I just bought a spare magazine for a sako 75. I was told it was a .243/.308, which would have fitted my III action, but now it's turned up it's for a longer cartridge, I'm guessing .270/6.5x55/.30-06 type IV action.
I paid 22.50 including 1.15 postage, so presuming it costs the same to post again I'm looking for around 24.00.
Before I send it back to whence it came, I thought I'd ask if anyone on the site was interested - pm me if you are. These magazines are like hen's teeth - if anyone has one for a type III let me know!
