Late post, apologies, responding to xausa's query:
Quote:
my Mini-Thirty is chambered for the 7.62X39 cartridge, which uses a .311" bullet. Surprising that a .30-30, with its .308" bullet would shoot accurately in such a barrel
The stainless mini-thirty barrel mentioned was indeed originally chambered for the 7.62x39 cartridge, but was .308 or .309 groove diameter, ie the bullet swages down a couple of thou in the throat. I was led to believe that this is the case with all Ruger mini-thirty barrels. Does anyone here know for sure? Have you ever slugged yours, xausa? Now I'm curious....
Also, the tough Ruger stainless barrel-steel might add strength to the otherwise thin tenon to overcome any tendency to bulge the chamber with .30-30 factory loads.
A bulged chamber would almost certainly mean a stretched action at the front, a pretty scary thought!
I can only reiterate the urge for caution in previous posts.
