Single Six vs. Ruger Mk. II

[ChiefPilot]

I took my first revolver out tonight for the first time - it's a Ruger New Model Single Six with the .22 and .22 magnum cylinders. As this is my first revolver, I was comparing it against the closest other handgun I have, which is a Ruger Mk. II Target. Interestingly, although the Mk II has a 6 7/8" barrel while the Single Six has a 5 1/2" barrel, they both seem to be about the same length. Wierd.

Anyway, the first thing I noticed was that the Single Six just sounds "different" when shooting; it's not really quieter but more "dull" sounding. I think this is because of the gas escaping around the forcing cone, which leads me to my main question: Which design loses more energy - the revolver or the semi-auto? It seems like a lot of gas escapes between the cylinder and the forcing cone on the revolver, while the bolt has to be pushed back with the semi-auto.

Thanks!

Between a blowback-operated semiauto and a revolver? Call it a wash. A single-shot pistol would certainly give more velocity, but this is probably due more to the extra length of barrel than any gas loss.

I'd suspect that the auto

Would be eekingn out a bit more oomph, ammo for ammo, over the revolver. Not only because it's got a bit longer tube, but the fact that bolt stays closed longer than you might think before it cycles.

BTW, you've now got a pair of the funnest .22 handguns known.

The barrel on a semi-automatic is measured from the muzzle to the breech face.
The barrel on a revolver is measured from the muzzle to the rear of the barrel.

If you were to measure your Single-Six from the muzzle to the breech face it would be close to the Mark II length.

You'll get more fps out of the Ruger. Maybe 50 more.

Theoretically with identical barrel lengths the semi-auto should give higher velocities because there is no barrel-cylinder gap. In reality only shooting through a chronograph will give you an exact answer.

hi

there isnt enough to worry about. the revolver and the auto will be to close and then you can shot a .22 mag. in the rev. to MORE than even things out.
