Well, Bearhunter,
Thanks for the kind words.
Sharing our experiences is what forums are about, I personally hate when it turns to personal attacks and stubborn discussions...
In fact Ackley himself - in his 'Volume II" - speaks about the respect we owe to the pre-98 Mausers for what they are; desing of the less than 60 000 PSI MAP calibers era.
Since the huge amount of Swedish Mausers, M/96/38/41B (M/94 to a much lesser extent), FSR, CG63 and CG80 have shown in America, we can document more and more of blown guns, mostly in 6.5X55. While this does not happen everyday or weeks or even months, we know several well documented cases.
And, as far as I can tell, they almost all involved pretty slow burning powders - with what one would consider reasonable pressure.
We also know since a long time that set back occured - creating excessive headspace - on some reworked M/96 by Kimber (well, Kimber is a complicated story). This is likely due to lug lapping, which, on a old Mauser, removes the case hardening layer to a point where it just can't be strong enough to handle the pressure without deforming.
Anyhow, while being a much better action than the 54, early Winchester M/70 were also known to badly handle escaping gases from a case head rupture when heat treatment or steel purity was not there. The modern alloyed steel qualities are used to compensate for lack of safeties Paul Mauser introduced in his M/98 (especially larger steel ring and large gas handling capabilities).
Like for the Springfield '03, they used alloy steel instead of the plane Jane low carbon steel used by Mauser. Once they've learned to control the heat treatment better (it was pretty now then and the same went for the P-14/M17), they've been able to make these rifles much better - even if they lacked the extra built-in safeties of the M/98.... Even Ross used swedish steel for it's purity.
With today's processed steel and machinery, it's much easier to monitor heat treatment and to keep the limits and fits very sharp... but to my point of view, modern production rifles often loose a lot of personality in the process...
Finally, if I had to build a high power (60 000 PSI and UP, including Magnum calibers) rifle using a standard lenght cartridge (3.340" or so) on a Mauser, I'd stay with post WWII production, like the triangle FNH - Santa Barbara (P-H 1100, 1200) - Zastava (or Mark X, Rem 798) or a Brno - ZG - ZKK - Cz or a HVA 1640, or even better for a Magnum, if one can find one, a rare Brevex Magnum Mauser.... but that's another story
