The round block '02 Webley wont take a 30-40 without troughing out the top of the block. The rim is too big in diameter and in stock form, the block doesn't drop far enough to allow it. It may fit if you don't mind holding the lever down all the way when you load it and then pushing the case home against the extractor while closing the action... I think the 30-40 would be far too powerful for this action anyway.

Interesting, must be close then. The .240 Flanged has a rim diameter of .513 vs .545 for the 30/40 Krag. That is assuming you do not need to hold the lever open on that little H&H rifle. Pretty sure the .240 has a higher operating pressure than the .30/40. Could be wrong though, hard to find much on the .240 online. Will take a look at some of my library and see.

What kind of pressures did your model use? I see the CIP max for a 30/40 is only 47K PSI, not what I call high pressure.

Also I did add a small radius in the vertical corners of the square BB mortise to reduce the problem of stress risers in the corners. To not do this would be dereliction of good engineering and design concepts. In other words, a Ballard, a Sharps, or a Winchester 85?

I dont know if your computation can take into consideration, the shape of the cartridge itself. Assuming, as most Ive read does, that the cartridge is well adhered to the chamber walls at 10,000psi, a straight walled cartridge would inherently have less back thrust than a tapered cartridge thus imparting less force upon the breechblock for the majority of the pressure curve. The OD / ID of the barrel shank and how much meat the action adds may be as important to consider in these smaller actions than the block design. H&H also chambered at least one of these small 02 actions in 22 Savage HiPower. That has 40K + pressure and a very tapered case.
