What does your own "reasoning" tell you!? ..........................


?
Until the "quality made" Remington Model 710 rifle came along, EVERY all-metal rifle action I was aware of could be disassembled/reassembled/customized/rebarreled ad ifinitem as long as the action was cared for and reasonably well-treated.
In other words, all rifles I was aware of prior to the M710 could be expected to outlast their owners of several lifetimes of shooting! .............
Typically a barrel wears out after a couple thousand, few thousand, or even 10,000 rounds of shooting depending on the cartridge and load-intensity. An an action will outlast [potentially] MANY MANY barrels!
Apparently the M710 action cannot outlast even ONE barrel! The story about the one .30/06 M710 becoming loose and falling nearly apart is about the third time I've heard of that happening.
Also, if you buy a M710 in whatever cartridge you get at the onset of ownership, that is what it will stay for its VERY SHORT and QUESTIONABLE LIFETIME! M710 actions cannot be rebarreled after leaving Remington's factory. Remington DELIBERATELY made their 710's to be that way.
