7.62x39 chamber

[CENTEX BILL]

I am working a deal for a PPC sixe bolt for a Remington shortaction. I have a spare Remington 722 that I would like to barrel to 7.62x39. I have a new take off SS 300 Short Remington Ultra Mag that I could chop the chamber end and rethread and rechamber. That will give it a .308 bore barrel instead of .311.

I shoot mainly cast boolits so sized them down would not be a problem.

I remember discustion about ruger mini 30's have chamber with a tappered thoat so one coud use either .311 or 308 size bullets. Is this internet legend or is it such a thing???

Who would have a reamer for purchase or rent to cut such a chamber? Would accuracy be greeatly affected??



Thanks in advance,

Centex Bill

by the time you eiminate the short mag chamber will you have enough barrel left to thread and provide a shoulder for the recoil lug? might be better off selling your barrel and starting with something with a smaller chamber, or buying a shaw barrel. depending on what you could get for your barrel, it might not cost much more for a new barrel and you would probably be more satisfied with the results
