I'd rather have a SRH in 454 or 480, but something about it in 10mm seems sweet. Even though a Glock 40 will do the same thing for hundreds less. Hell for that matter a 6" barrel in my G29 will do the same thing.
But am I right to assume, the Ruger, you could load 220-230 grain Hardcast to longer OAL and get mo-powa from the 6.5" barrel?
Assuming the cylinder is the same length as the other SRH guns, you could load long, or ream for 10mm magnum.
Or both. It uses moon clips, so you could ream to 10mm magnum, and shoot 10mm-mag, long 10mm, standard 10mm and 40 S&W just fine.
Accuracy would nominally decrease the longer the bullet had to "jump"
Of course you will lose some pressure because of the barrel/cylinder gap so unlikely you would get the same velocity as you would with a semi-auto with the same barrel length.

Don't piss on a man's oatmeal. What's wrong witcha?
Whew! Almost $900!
Sweet though.

A revolver barrel is measured from the end of the cylinder to the muzzle. A pistol barrel is measured from the breach-face to the muzzle.
A 6" revolver barrel would have about 6.25" of bullet travel while a 6" Glock barrel would have about 5.35" of bullet travel. The difference is almost an inch. That would probably make up for any loss from the cylinder gap.

Some folks don't know this about the semi-auto barrel, when given the length of the barrel the cartridge occupy some of that length so the speaking length is shorter actually.
However, the speaking length is measured from the back of the bullet to the end of the muzzle.

By bullet to you actually mean cartridge base? Cause the back of the bullet would vary from load to load, depending on the bullet weight, style, composition and seating depth.
I meant the base of the bullet.
In that case I gotta disagree. There are a number of issues with that.
Speaking as an engineer your datum cannot be a variable. The base of the bullet would vary all over the place depending on a wide variety of factors.
Speaking from experience, the barrel length in a firearm where the barrel and chamber are contained in the same part, is measured, with the action closed, from the breech face to the end of the muzzle.
As an engineer you should know what I'm talking about. The speaking length is the amount of distance the bullet travel in the barrel. When you compare barrel length between semi-autos and revolvers they will be different.
Let's say you have a semi-auto and a revolver, both with 4.5" barrels. The speaking length on the revolver will be longer than the semi-auto because the cartridge will be in the cylinder, not the barrel like the semi-auto.
As a non-engineer retired goof, if you compare the distance from where the bullet exits the case to where it exits the muzzle. A bullet fired from a revolver gains the throat area of the cylinder and the length of the cartridge chamber over an identical specified barrel length semi-auto or single shot. Basically the length of the cylinder added to barrel length given identical chamber dimensions. Gas pushes for a longer period with a deduction for the cylinder gap in the revolver.
In the real world it's all angels dancing on the head of a pin. I had a 4" Security Six that would shoot the same loads almost a hundred fps faster than my 6" Security Six and the 6" had the tighter cylinder gap. The guys at Douglas Barrels (one of my hangouts) will tell you that they can make two barrels side by side from the same bar cut with the same tooling and the barrels will shoot differently.
In shooting it's all a SWAG until you pull the trigger.
I am not disagreeing that there is a discrepancy in the working length of revolver barrels vs semi-auto barrels.
I do now get that you are applying the music term "speaking length" to mean the distance traveled by the bullet, base to muzzle. The way I read it you were saying that the nominal length of the barrel was measured bullet base to muzzle, when in fact it is measure breech face to muzzle.
But, that cannot be defined as a spec, because it will be different for a 135 grain 10mm vs a 220 grain 10mm cartridge. The 135 will travel less distance before it exits the same barrel. Doesn't make the barrel any shorter.
A better reference length for comparing revolver to semi-auto would be to use the nominal length for semi-auto, and for revolver the nominal length + gap + cylinder length. Or just use breech face to muzzle for both.
That's not what I was talking about though but you got my point. Yes, the speaking length is a musical term but it make sense and I'm a musician. :D
I didn't say that was the barrel measurement but what the bullet traveled in comparison between the similar barrel lengths of the semi-auto and the revolver.
Rick got exactly what I meant and he also added that the cylinder added to the speaking length of the bullet.
