RedRyder21 - No, you're not crazy, at least not according to your post. Oh yeah, most folks would want to reload for that caliber becuase they like to shoot them a lot. You can improve on most any of the older calibers just by reloading semi-wadcutter bullets rather than the older round nose style. With the big heavy 45 slugs you don't need magnum velocities, the standard velocities will do nicely for the purposes you mentioned.
If at first you don't reload, just wait (lol), it will happen to you and you will wonder why you didn't do it before.
As for that particular revolver you mentioned - the 45 LC/45 ACP Rugers are fine revolvers - the Ruger is a strong son-of-a-gun that will take heavy hunting loads. And the 45 ACP cylinder is a plus when it comes to shooting mil-surp ammo. However, Ray Ordinica just compelted an article for Gun Tests magazine comparing some of the 'convertable' revolvers and found them to be more accuarate with the 45 LC than with the ACP cartridge, so shooting the ACP cylinder may not be as satisfying as shooting the 45 Colt cartrige.
Also, he found the offerings from Cimarron Arms and some of the other makers of old west reproduction firearms to be absolutely excellent and some of these can probably be had new, for less than even a used Ruger convertable.
I have toyed with the idea of a nice 4-5/8s" or 5.5" Model of the 1873 Colt as a field carry piece in 45 Colt, but only with factory level loads. It served well enough on small to medium sized game and predators a century ago, it will do the same today. JMHO. Mikey.
