Read Enhanced folks, the late production 629s (dash -4 and above) have the enhanced package as do later and rarer 625s. Linebaugh hiself has some extraordinary loads for the old long colt in the new S&Ws.
By the by John, your buddies over at sixgunner actually did a side by side Smith vs Ruger strength test some years ago using progressive hot loads......the ruger blew before the Smith!
Crazy hot loads like 454 Casull level in the Ruger Redhawk aside because only a handfull of loonys do that sort of thing, comparisons with industry standard pressures will/do show that both the N frame and the Ruger will normally out live the individual shooters.
Let's read John Linebaugh's own words off of Sixgunner's site shall we. I have included an excerpt regarding the above comments as well as the link to the entire article. Read at your leisure. Thank you.
This article contains proof pressure data from H.P Whites lab that Sixgunner used to test the Model 29 and the Ruger Super Blackhawk. Here is the excerpt:
H.P Whites lab reports states that the Ruger Super Blackhawk was destroyed in a controlled test at approximately double that Pressure. (80,000 CUP) The Smith and Wesson Model 29, also in .44 magnum caliber showed comparable results. Today we have stronger guns chambered for the .44 magnum (Redhawk prime example) but the Model 29 S&W and the Ruger Blackhawk gave life to the .44 magnum cartridge. The strength and design of these guns satisfied the industry at the time (1955) and the standards were set from these firearms.
You can read on and see that John Linebaugh never mentions a S&W gun again in this entire article, but tells how he chose the Ruger Blackhawk frames to build his custom .45 Colt loads on that were producing well over 52,000 CUP and they handled just fine. With such a well respected and knowledgeable custom gun builder as this, when he chooses to use a product, it speaks volumes of his confidence in it. Keep in mind he could have chosen the Model 29.

After looking around I finally found a site for Linebaugh Customs on Sixgunner's site. Take a look at it, I can't seem to find the words Smith and Wesson on it anywhere. Here is the link:

More of John Linebaugh's words on Ruger and Smith strength, the article is linked below the excerpt, please read it:
It may surprise many but the cylinder on the S&W .45 Colt is the same diameter as the Ruger Blackhawk. The webs (between chambers) and outside chamber wall are also the same. So basically the Ruger and S&W cylinders are identical in strength and dimension. We recommend handloads for the Rugers single action in .45 Colt caliber to 32,000 PSI levels.
While the S&W will take these loads safely such loads will greatly shorten the life of your gun. The frames on S&W are not heat treated thus are pretty soft. With loads that exceed what the gun can comfortably handle the frame stretches immediately lengthwise and then springs back. This all causes battering and soon your gun has excessive endshake. I don't know how long it takes to wreck a N frame S&W with heavy handloads but Jeff Cooper printed one time he saw a model 29 go out in the realm of 1,000 hot handloads if I remember correctly. I would agree that serious damage could be done in this amount of shooting with too heavy a handload.
In general, the S&W may not be the strongest sixgun. We know other models will shooter harder and faster

In the opinion of a custom gunsmith who knows much more that this lot, the Ruger is stronger than the Smith in design and build. I am sure there will be more comments from the Smith crowd, please enjoy and I look forward to the discussion. Have a great night.
