Commercially "remanufactured" ammo ...

Perhaps I'll have to plead ignorance here Thomas, but what procedures are you referring to that are not basic reloading procedures for any semi-auto rifle?

Some things are obvious - you need to full length re-size and depending on your chamber dimensions you need to use small-base dies.

You need to use hard milspec primers in any rifle with a floating pin.

You need to use appropriate powders and appropriate bullet weights.

You need to ensure your brass is trimmed to within spec.

You need to seat your primers below the surface of the rear of the case head.

Beyond that, what are you specifically referring to? All reloading carries inherent risk, but I'm not aware of any special M14 procedures that are not typical good practice for reloading semi-auto ammo.

I realize this may be a bit of a tangent from the discussion, but can anyone comment on the potential use of commercially "remanufactured" military ammo (eg. BVAC M-80)? Does the commercial process generally reload to consistent specs, such that it will eliminate the above issues altogether?

you pretty much nailed it all.... my cautions are directed to those who may have reloaded for a bolt gun but are just now reloading for thier M14. you have to admit it is a whole different ballgame. remember, this fellow is comparing his trw bolt equiped m14s with way under safe headspace to his bolt action rifle in the same calibre. if he were to reload for both based on the headspace dimensions he is claiming..... you have to admit..... bad things may happen hehehe and we don't want that.
 
M14 SPECIFIC RELOADING CONSIDERATIONS:

1.] Bullet weight - heavier bullets at higher velocities tend to batter the M14 op rod and bolt [ one of the reasons I switched to the rotating bolt AR 10 ... 180 grainers are no brainers in an AR 10 ]

2.] Newton's law of physics .... the reciprocating mass involved in an M14 gas cycle MUST stay within certain parameters for maximum reliability and durability.

3.] Gas port pressure on the M14 is basically non-negotiable, which means either a gas bleed off mechanism for overpressures,
OR powders with the precisely correct burn time.
Can you say the word "RETARDENTS"?

Other than the above, and a few other tricks and tweaks,
it ain't rocket science.

the M14 is a well matured, robust system so all you really have to do is
READ THE STICKIES,
and use your Google FU to search out the well known data.
BTDT,
don't reload much .308 for the M14 any more,
but if I did,
I would be concentrating on LIGHT RECOILING tactical loads for CQB

eg
110 gr sp at hyperspeed
125 gr sp at 7.62X39 duplicate ballistics,
etc
