See the attached pictures. How high should the rear of the bolt be when it is locked? Should the rear of the bolt rise so that it is flush with the top of the receiver? When my bolt is locked the corners of the bolt are pretty even with receiver, but the center of the bolt is 0.070 lower than the top center of the receiver. The rifle loads fires and ejects without any problems.

That is the way my two look.

The reason for my original post was my interest in how much stress the receiver receives on the locking surface. I am not an engineer but I made some calcs and was kind of surprised at the load on that area. I measured the locking area on my gun. My calculations ignore the friction forces of the case and chamber so I guess they could represent a "worst case" example. Like i said these are amateur calculations so feel free to critique.
Your calculations look correct to me, but I don’t think failure would present itself as a cracked receiver. Does the action show any signs of opening upon firing? Does the rear of the bolt drop or the lever open? Does the brass have any bulges at the base? I had this issue with a 99E and fixed it by shimming the groove that the lever pin rides in. It’s that fit that seats the bolt.
I was just surprised at the compression load and thought more along the lines of the locking surface deforming over time.
The 99 receiver and locking system is much stronger than those of other tube magazine lever guns at the time. Ever see a Winchester 94 in 308 calibre ? Nope.
I do remember Winchester coming out with the Model 94 chambered in 307 Winchester, which is a version of the 308 Winchester with a rim. The model 99 Savage in 308 winchester has to be a longer action than the 300. I would like to get my hands on a 308 model 99 to see what other changes they made to handle the longer 308 round.
