Andy,
I have a stainless Blackhawk, 5.5" barrel, in 45 Colt caliber, and for all around fun shooting it's my absolute favorite revolver!
The 45 Colt has the option of being loaded with any ammo on the market, except that which is specifically loaded for the strong 5 shot custom Rugers. Light plinking loads will bowl over most targets at very low recoil, yet it can also be loaded to safe energy levels exceeding 44 mag standard ammo, should you ever decided to take it big game hunting.
There is very good reason for the 45 Colt cartridge to be so popular over a hundred years after it was first produced! It is simply the best combination of size, weight, and accuracy ever made!
I also enjoy shooting my 357 revolvers, but they get very little use, since the 45 Blackhawk wormed it's way into my affection.
And of course, I had to have a Marlin lever action to go with the Blackhawk.
Bill
