How Good are they Supposed to Shoot

Apparently, you have made friends with the !

My experience:

Discounting the shooter, a good revolver will hit a 2 inch target most of the time, at 25 yards. ( 4 out of 6 )

It'll hit a 6 inch target at 50 yards... most of the time. ( Again, 3-4 out of 6 )

At 100 yards, figure that with a 12 inch target... at least 2, maybe 3, out of 6.

If you have a great revolver, you can double the number of times you'll hit those same targets at those distances.

Remember, this is just mechanical accuracy.... it has nothing to do with how well the person is or is not holding/pointing the gun.

And for what it's worth, hitting a tall skinny object is usually easier than hitting a low, wide one. Windage is easy... elevation, not so much. At least for me.

P.S. I don't consider that there's any practical difference between BP and cartridge guns, other than load, and consistency with loading. If you're sloppy with loading a BP gun, you are in essence firing a different load every shot. Might be 25 grains, might be closer to 30. And if you cast your own bullets, and are equally as sloppy... well, there goes the whole ball game.

I know a shooter owning and shooting a 1858 remington ( a real one, not replica ! ).
He was able to do 2" groups at 25m ( about 25 yrds ).
