I don't really see how you can say the same designed guns that fire 10MM
are underdesigned when used with .45 Super.
Colt, Glock, etc. use the same basic guns for 10MM as they do for .45 ACP, with spring changes, and maybe slightly stronger materials, and I'm not really sure if this is true.
The advantage of the .45 super is in bullets ranging from 230-260 grains, bullets the 10MM can't fire, or aren't common. Don't have any 10MM loads for 220 grain bullets.
However, a 200 grain Truncated cone, @1200 fps in 10mm, or .45 Super would, it seems to me, penetrate hog or bear well. Not ideal, but better then a sharp stick.
Looking at the recoil figures, I do wonder that if for longevity wise, 200 grains at 1200 fps might not be the ideal combination for a 1911 style firearm.
John Moses Browning originally started the .45 ACP with a 200 grain bullet.
His main concern was horse penetration. Detonics suggested 200 grain bullets at 1200 fps, and I shot those every other day, for 2-3 hours a day, at 1200 fps, for 5 years, with no harm to my Detonics Mark VI.
Dane: like to hear your pig hunting stories.
Odd part is the 255's at 1010 fps run Recoil Energy of 12 foot pounds, and Recoil Velocity of 19 fps. The case capacity limits potential recoil.
And as for running the guns too hard:
This isn't 1900. Metals are WAY stronger. The high end of .45 ACP is a 230 grain @ 940 fps 800-x. Recoil Energy of 8 foot pounds, and Recoil Velocity of 16 fps. So, do the math.
Between recoil energy you have 20% between .45 Super and max 45 ACP, and, this isn't even plus p.
For Recoil velocity you have an even smaller amount. 16 fps vs. 18 or 19 fps.
I'm not buying that a modern 1911 design, or Glock, can't handle that minimal increase in recoil energy with either springs, special guide rods, or retiming the gun.
If we start barking around the .460 Rowland, we have a whole different kettle of fish.
How about links for reasonable 10mm ammo? The only time I see it is looking at Buffalobore, and Double tap.
Just looked at Double tap, and they do load 1120 fps 230 grain LFN's in 10MM, for about 1 dollar a round. I'd think that's pretty close to the .45 Super, enough so a pig wouldn't know the difference.
