Re: MATCH vs REGULAR BRASS
As with most things in this sport, it depends.
If you buy say, 1000 Lapua .308 Win cases at about $33/100, you have about $330 into them, and you still have to do the basics, i.e. trim, chamfer, debur, make a cursory pass w/ flash hole deburrer, primer pocket uniformer, etc. Probably won't take a whole heck of a lot off, and they are (in my experience) disgustingly consistent, to the point that it was *awfully* tempting to just run them thru a F/L sizing die, for good measure (the headspace was amazingly consistent as well) to round out the necks, mainly (shipping/storage boo-boos), and go shoot. Probably would have had no problems.
Now, if you are willing to spend the time and effort, you can certainly prep Winchester brass (my current 'preferred' domestic stuff) to just as good as better. And as the Winchester costs (at least) half what the Lapua does, you can afford to cull cases that are just plain outside a given set of criteria, be it weight, whatever. The extra $$$ can be put towards something nice like a fancy neck turner, a Gracey trimmer (or power neck shaver), better powder measure or scale, etc.
For me, one issue that led me to start using Lapua brass when Winchester had been working pretty darn well, was that my chamber is pretty much on the *maximum* end of the spectrum, in almost every dimension. Lapua cases (in .308) have a thicker case neck, therefore I'm working the necks a fair bit less during resizing, and hopefully not having quite as much runout issues, and hopefully the case life will be as good or better. Also, the web area in front of the extractor groove on a Lapua .308 is 0.4685 or so, vs 0.464 or 0.463 on a Winchester, so again, less 'extra' for the brass to have to expand into.
All in all, if I had a snugger chamber, I'd probably just use up all my Lapua brass, and then go back to Winchester, if it were me. Most of the operations to get a Winchester up to par w/ Lapua only have to be done once, and w/ some good power tools (Gracy Power Neck Shaver for neck turning, and either a Gracey or Giraud trimmer for trim/chamfer/deburring) can be done right quick like.
