I'd give a hunk of my backside for a SIG R93 in a SAAMI minimum chamber 7-'08. It may be the perfect 7mm cartridge, considering all the possible end uses of a rifle cartridge.
A friend of mind sent a 700V in 7-08 off to a place in Tehas to get the barrel set back and rechambered with a tight neck. Now that's a shooter! BUT, if he had it to do over again, he would forego the tight neck and just go with a SAMMI min chamber.
7mm-'08 is a fantastic cartridge.
For years, the 7mm bullet was considered the perfect caliber for a personal weapon (find Krupp and DuPont ballistic research in library). It may be, but if it's not, then it is probably the 6.5mm or 6mm. Right in there (6mm - 7mm) is where air molecules and air mass for external ballistics, range of different bullet masses available, all the available powders and materials technology for barrels (pressure chambers) all comes together.
Of course, all this is without regard to the practical, economic limitations of whether a cartridge is available in a commercial loading. But then, if you're not reloading, you're limiting yourself in ways you'll never know, IMHO.
