Spinsail-- I feel pretty confident to 100 yards with a 45 Colt. We can get to 100 yards on antelope in southeast Colorado. I'll have a rifle with me as well, but the 45 Colt will be my first choice. Not a long barrel. I prefer a max of 5.5" on my revolvers. Might scope it, but I doubt it.

The 45 Colt is my second favorite caliber. It can be loaded light enough for one handed plinking for a 10 year old, or loaded hot enough that a full grown man better use two hands, and hang on. That 45 Colt SBH you mentioned with a 7.5" barrel is the only "long barrel" I wouldn't mind having. My customs are always done with a 5.5" barrel, but I might just get that 7.5" this year, and leave it stock.
