The limitation is not on the revolver or the cartridge. The limitation is the shooter.
A good model 29 Smith is easily capable of killing deer at 100 yards and beyond. The problem is the shooter is not.
You have to make a commitment with a revolver. And that takes practice. And by practice I am talking 1,000's of rounds. It is really a reloaders game, and better yet, you even need to cast your own bullets. I can put a 1,000 rounds down range for about $100. You can't do that if you are relying on factory fodder-or at least I could not afford it
If you are serious about it then set your initial limitations to about 30 yards, and practice at that distance. This is not an easy thing to do. Fifty yards is a bit far too start off with. But the coffee can idea is a good idea. Don't shoot at targets at the range. Go out in the woods and go for a walk, and shoot at stumps or any other targets of opportunity. That is how to get good.
