For fun Jerry you could calculate how much pressure 41 grains of Tight Group in a 7-08 case with whatever eternal capacity and weight bullet seated to standard oal. Now that would be fun, to see if a Remington could handle the pressure.
It's a lot.
I did some calcs for another thead a year or 2 ago comparing various barrel shank diameters using maximum pressures of something like 75,000psi. I didn't do any pressure calculation from loads. It is a specialized branch of engineering and I am not a powder expert. Even the pressure calc isn't easy. If you use basic hoop stress formulas you will predict that all barrels will fail with moderate loads. You have to use Lame's equations for thick cylinders. It isn't trivial but if you're interested google it and I think you'll find some plug-in calculators that do the arithmetic for you. Strength goes up with the outer radius squared.
Like I said, if nothing happens to create an upset condition, they all pass. This is pretty obvious since Savage wouldn't build an unsafe rifle for market and each rifle is proof tested daily by thousands of owners.
But when pressures go up way beyond design, and we know it happens, we've seen the photos, usually caused by a bonehead move, different rifles respond differently. In my experience when this happens to a Remington, the bolt, barrel nose, and action weld themselves together and the not-very-dramatic postmortem photo is an action ruined and cut open with a milling machine to show the resultant mass of fused metal. When this happens to a savage, AR15, or some other rifles, the dramatic picture shows the dozens of parts that were gathered up around the range. I've seen old mausers fracture because they are hardened so much they are brittle.
There just isn't as much metal there to contain the pressure. Additionally, the heat treatment and resultant ultimate tensile strength may not be as great. Like I said, I'm not a gloom and doomer. The primary protection we all use is extreme care not to do such a move to put extreme pressures into our chambers.
But a large capacity case in a smaller diameter shank has less margin for the very unlikely errors that occasionally cause these photos. Above I said I wouldn't do it. I didn't say that the OP shouldn't do it.
Every day we could be safer by staying in bed. So we all choose how much risk we are willing to take. I grew up poor and took lots of risks. Now I take less. If I were richer, I would probably take even less risk. This is America, we all make our own decisions every day. I very seldom criticize anybody who is at least reasonably sober.
Be safe,
Jerry
PS It is hard to impossible to calculate when a component will fail. We have to assume it will fail at some stress. you can look up the ultimate tensile strength of most any material. However, what you are looking up is a specification for the minimum allowable tensile strength. So when you find 410 stainless has a minium ultimate tensile strength for a given heat treat condition of 120KSI, it might actually not fail until 180KSI. And a manufacturer might specify subtle changes or heat treats to raise the ultimate strength. All you can really calculate is a maximum pressure where a component made to the specified material specifications will NOT fail.
honestly I don't think the extra .03" would make a mess of difference with the OD of the action with that kind of powder charge :-O as well as the Savage has a blast ring just in case something stupid happens. Honestly since I started messing with the Savage actions I really don't miss the extra work I'd perform on the Remington actions but I did ask for opinions so thank you sir.
