GK, I have built a lot of rifles on Mausers that I would stack up against any Sauer, or Blaser. Not to show disrespect for Sauers or Blasers. They are very very good, but I can't say they are any better at all.
It's very common for my rifles to shoot well under MOA, the workmanship is (if I say so myself) excellent, and you can't get any more reliable then a well made M-98 Mauser system, when i's set up the right way for the cartridge it feeds.

"New and improved" is usually only new.

I have yet to see something I'd call a substantial improvement in a bolt action.

Designed in 1898, it's now 102 years old, and nothing has really beat it yet in the bolt action designs.
That's either a superb testament to the design genius of Paul Mauser or a shame on all the designers that have tried since then.

Perhaps the Bolt action was perfected in the M98 design, and that's why we can't come up with anything better. Every bolt action I know of that I would call "as good" is really a Mauser design at its core.
