Interarms Virginian Dragoon
Caliber: .44 magnum
Barrel: 7 1/2 inches
Best Load: 6.4 grains Winchester W231 powder
with a 240 grain Lead Semi-Wadcutter
Lot of shooters who see it think it is a 3 screw ruger and it
shoots point of aim when I take the time to try. Very affordable
well built single action army clone.
Caliber: .454 cap and ball revolver Barrel: 7 1/2 inches Best Load: .454 round ball with 25 grains of Pyrodex P and Thompson Center bore butter to seal cylinders Very faithful Italian reproduction unfortunately this one is used the least as it rarely if ever goes five shots without a misfire or dropping a cap in the action and failing to function at all. (not recommended for competition but fun for just plinking) out to 15 yds it is more accurate than would be expected.
Caliber: .454 cap and ball revolver Barrel: 12 1/2 inch Best load: .454 round ball with 30 grains of Pyrodex P and Thompson Center bore butter to lube bullets A fantasy black powder revolver that hasn't failed to fire since I purchased it (over 500 rounds). Accurate out to 50 yds due to long barrel. A pain in the rear to draw for same reason. Usually worn low crossdraw style on weak side. 
Ruger Old Army (Converted)
Caliber: .457 cap and ball revolver /R & D Guns .45 Colt Conv Cylinder Barrel: 7 1/2 inch Best load: .452 LSWC with 30 gns Pyrodex P in a Remington case. I Finally got tired of the 1860s failure to function when needed and the overlength barrel of the Bison and bought this after trying a freinds. So far I love it (even though I forgot the powder measure for the first match). Since converting to center fire I really do enjoy using this pistol. The only problem I have had so far is that for the first few hundred rounds the firing pins would stick unless well lubed. I highly recommend these new fangled conversion cylinders. 
Ruger Vaquero
Caliber: 44/40 Barrel: 5 1/2 inch Best load: Unknown as of yet. I picked this one up from a non cowboy action shooter who said it couldn't hit the broadside of a barn. This has become my favorite pistol to date. Modifications so far consist of a very excellent spring kit which has had a noticable improvement in speed. For anyone interested these can be obtained from Har Trigger and I highly recommend them due to their price and the improvement of the action once installed.
