Dear all,
Please can you tell me if it is feasable to re-chamber an existing barrel? In my case I would like to re-chamber from 7x57 to 7x57 Ackley Improved, with the 40 degree shoulder to fit the commercially available reloading dies.
I have seen on many gunsmiths web-sites that they refuse to do this job, is it because of the factory chambered barrel steel being too hard to work, presumably being work hardened during the button rifle swaging process?
I realise that this is a fairly silly enterprise, there being absolutely nothing wrong with the 7x57, but I just have a hankering to have something a little different And as P.O.Ackley says in his book about the 7x57 AI, "It has almost ideal powder capacity for the 7mm bore and produces very satisfactory ballistics."
Regards, Simon
