'Clark,
I cain't know,whatcha' cain't know...so pinpoint that which ain't clear to you and I'll clarify.
I'm never not crystalline.
'100,
"Mexican Match" is one of the oldest of the Old Injun' Tricks and reliably bears lotsa fruit. It were derived many moons ago and is most oft attributed to the Sillywet Crowd,which is likely the very case.
In it's most simplistic form,one simply sources a goodly supply of what is typically Factory Ammo(I personally wouldn't shoot anyone else's Reloads on a [bleep] dare) and lovingly yerks the issued boolits outta them. Lotsa ways to do this,but my preference is a collet puller,so as to be nice to primers and curtail beating on live rounds in general.(grin)
One can then swap out the pulled boolits,for one of superior quality,form or terminal affects...or all 3 attributes. The Sillywet Crowd's focus was on 308Ball ammo and the FMJ's was removed and sumptin' akin to a SMK seated in it's place,retaining the issued case,primer and powder charge. In the days of dirt cheap Ball Ammo,it was a great way even then,to stretch a buck and realize MUCH improved performance.
I've done it with bajillions of rounds,in multiple chamberings and still do in 308,now and again. Key things to keep in mind,is that NATO pressure levels are at or exceeding Sporting ceilings. Most FMJ's don't obturate as happily as a typical cup/core offering,so that in itself acts as a pressure bleed of sorts. I've never had anything "weird" pressure wise with 308 Ball in any boltgun,but sloppy headspaced MBR's are another story and not the impetus here anyhow(thus far). You don't wanna pull 147gr Radway Green and stuff it with 175SMK's atop the issued powder charge.(grin)
Here's how I roll and tools of the practice.
A pallet of 308 Ball is a nice way to start. I then pull with the aforementioned collet means(illustrated in pic) and then deburr the mouth and seat a suitable projectile with a Comp Seating Die(shown),in accordance to a given throat.
I'm at ease in yerkin' 147's and substituing same with a 150 mainstream cup/core,which will bleed pressure as cited(due happier obturation). In conjunction with that practice,I'll again bleed pressure off the issued powder charge and componetry(brass volume and primer temp),by going moly and refraining ANY crimp...even in MBR's.
Pulled/laquered/crimped boolits,destined for the garbage can and the issued brass/powder/primers awaiting happiness.
Cursory run,ready for a Range Trip,to establish initial zero and come-ups,via chronographed feedback.
Typical platform
The backside of the equation,is that you've now got more brass for a given platform,while having reaped vastly improved issued "performance" levels of a given Batcha' Bulk Ball. Win/win/win.
A deviation of the theme,is to pull boolits and then dump the powder in a thrower and re-meter for even more Precison(better ES/SD values)...or to make use of a boolit that's not aligned with the issued charge weight's pressure levels. Very easy to resize to 7-08,243,etc and control neck tension and squirt a killer boolit to boot. Lotsa ways to sking the cat...though I always start at the ass hole.(grin)
Long way of sayin',I [bleep] hate 308's.(grin)
'Cub,
Not all things is equal,that's a certainty.
I get it that some don't 'Load and they gotta suffer,what they suffer. That being said,as Factory fodder goes,there' gonna be som default chamberings that are gonna reliably shine brighter than others,due QC,superior componetry and literal demands. The 223 and 308,the most shining examples there.
My initial point was/is,that I could not in good faith outright cuss the mechanical aptitude of ANY 25-06 boltgun's relative merit,by making it suffer Factory Fodder and weighing that feedback as a sole barometer of mechanical evaluation. It may or may not shine,where with the other chamberings I cited prior,you KNOW WTF is going on,as ammo of repute is readily available. Therein lies the crux.
A guy makes his own "luck".
Hint.
