I am going to purchase the 9mm/.357 blackhawk convertible, and i was wondering with a 6.5inch barrel, at 15yrds how accurate will the gun be shooting the 9mm cylinder be, than at 15yrds with the .357 cylinder?
I have a .22lr single six convertible, so i know the difference in accuracy between the .22mag and the .22lr for the single-six.
I have had mixed opinions on accuracy, so i was wondering what you guys thought.
Any feedback will be nice.

At 15 yards I bet you won't be able to tell the difference.

My 4 5/8th" barrel shows little difference. My 6 1/2" barrel shoots 9mm very low. I have no clue as to why. Byron

I find the 6.5" barrel balances funny.
I wish I'd have bought the 4 5/8" barrel instead.

Accuracy aside, the 9 mm usually has a lighter bullet than a 38 or 357 and would therefor be expected to shoot lower at short ranges. If you had a 124 grain bullet in the 9 mm and a 125 grain bullet in the 38 or 357 I would then expect them to shoot closer together.

I will be trading for a 4 5/8" Blackhawk 357/9mm convertable myself this Monday. So I will eventually compare the 2 cylinders and try to post some results.
The 9mm will obviously have a lot longer "jump" to the barrel and the bullet being slightly smaller in diameter , usually .355".
I think there was a thread on the 357/9mm convertable on the Ruger forum and most seemed to indicate the 357 being more accurate. The 9mm certainly being good enough for plinking.
I have a 6 1/2" 357 Blackhawk that has really surpised me with it's accuracy. If my 4 5/8" is anywhere close with 357 loads I'll be pleased. It will be intresting to see how well the 9mm compares in accuracy.

I had a 4-5/8" convertable a few years back. At 15 yards no real accuracy difference.
Single action revolvers of any brand are prone to shooting light/fast bullets lower than heavy/slow ones (out to 25 yards or so) because of the high bore axis and rounded grip shape.
The gun starts recoiling up before the bullet leaves the barrel. A heavy/slow bullet generates more recoil and spends more time in the bore, lifting the muzzle. A .38 spl 158 LRN will hit much higher at 25 yards than a 9mm 115 or even a .357 110 jhp.
By the time you get to 50 yards or so, the faster, flatter shooting bullet will start to hit higher than the slow, rainbow trajectory of the heavy bullet.
Longer barrels make for more 'bore time', increasing the effect.
Grip strength also effects how high the bullet strikes. The firmer the grip, the lower the bullet will strike.
Elmer Kieths' book 'Sixguns' is an exelent read for anyone who likes revolvers.
