There is a company that sells a ramped barrel with full chamber support for the cartridge and a 26 lb double spring conversion kit for $200. They claim the 230gr can be loaded to 1200fps with that conversion. I have been thinking about buying a ramped barrel and see what kind of velocity I can safely obtain with 24lb Wolf spring.
What Plainsman is referring to is called the .45 Super. The late Ace Hindman and Gunwirter Dean Grennel came up with tihs cartridge several years ago. There is at least one chapter dedicated to this cartridge in Grennel's "The Book of the .45".
Several years ago (about 1990 or thereabouts) I contacted Ace Hindman (owner / operator of Ace Custom .45's) about the .45 Super. At that time I alaos purchased a Conversion Kit for my S&W Model 645 (which has a ramped barrel from the factory). The .45 Super as originally conceived was to use a stronger cartridge case to make .45 ACP Cases out of (they used cut down .451 Detonics brass) and to use a Ramped Barrel with a special Recoil Spring System to load the .45 close to the pressure levels of the 10mm.
While I did not achieve the velocities reported by Hindman and Grennel (I never pushed it that far) I did enjoy a increase in performance with my handloads that pushed a 185gr. Nosler Jacketed Hollow Point (the bullet recommended by Hindman and Grennel) to almost the same velocities a 100mm Auto can push a 180gr. Bullet.
While I never did get to harvest a Whitetail with this Gun / Load combo, I did manage to shoot several Whitetails that needed dispatching at the scenes of Vehicle / Deer Accidents. Most of these deer were examined to inspect the damage done by these experimental loads. In my opinion the .45 Loads I put together were quite devestating, and in every instance the bullet exited the Deer provided I did not hit a shoulder bone.
Now I have not shot a 100mm very much, but at the time I had my converted S&W 645 a buddy had a S&W Model 1006 in 100mm. We shot both handguns (target shooting) quite a bit side by side. The thing that was apparent to me was that no matter if I was shooting light cast bullet handloads, factory loads or my .45 Super loads the .45 had an edge in accuracy in these two handguns. I would say the shootability (recoil and recovery from that recoil, and muzzle blast) for my .45 Super Handloads was about the same as the 10mm.
What does all of this mean. Well it means that if you are a dedicated handloader and like to experiment the .45 ACP in the form of the .45 Super can do anything a 10mm can do and more. BUT the key is if you are a Handloader and willing to put in the time experimenting with loads.
On a different note I once had a Coonan Arms Model B 1911 Style .357 Magnum Semi Auto Handgun. This too was an interesting Handgun that fired Conventional .357 Magnum Ammo. However due to the closed breach design of the Semi Auto this handgun gained up to 200 FPS over a similar length revolver in .357 Magnum (ie I actually chronographed the same ammo in both types of handguns).
In the end this is kind of like a Ford vs Chevy vs Dodge debate, and each individual user will have his or her own personal preferences. To put it a different way, some men likes Blondes while some like Brunettes while others like Redheads.
