I am not an engineer and I will not give specific advice on the 414 or anything else. My "rule of thumb" is the factory. What did the factory see fit to chamber the gun in. De Haas in Bolt actions warned against rebarrelling WW I Mauser 98's to .243... you can get bolt set back at these slightly higher pressures and exesssive headspace--45K CUP old, vs. 55K CUP for .308 family. The original Stevens was called a "boys rifle" for a reason. A boy who was "anyone" had one to play with. Just like the computer games today... They were not strong or particularly well made. Cheap. And there were cheap imports copys less well made!!! Today, rimfire works at approx. 25% more pressure. Today's guns should take that. The other consideration, physics, the larger diameter case spreads the pressure over a larger area. Most obvious, T/C Contender works fine with .223 at 55K CUP, but cannot handle .250 Savage at 45K CUP. Case is larger in diameter. I would guess that a modern remake would handle the rimfire .17s, Mach ?? in guns factory chambered for long rifle, HRM in guns chambered in .22 Rimfire magnum... Hornet is a bad gamble, considering the cost, for my money. (I am CHEAP.) Now if the reference to the 414 and the Stevens 44 I saw is correct, then you should be able to handle the .30/30 family which works at 40K CUP and includes the Hornet which is less load being smaller in diameter... luck
