Now I’m no engineer (just a draftsman by degree) but I do play one at my day job  ;)

The pressures of the two rounds are within spitting distance of each other so we can check that off the list.

The next issue would be bolt thrust.  Since bolt thrust can be calculated by multiplying internal area of a cartridge by its pressure, well, I don’t have to work that math to see the Hornet will have much less bolt thrust. 

Pressure looks good, bolt thrust looks good.  I think that’s about all there is.  Am I missing something else?  I’d feel pretty safe firing one.
