Sure, It's the size of a truck muffler though. And, no help for the
"crack".

ah...actually..its no bigger than about 1.75 in diameter and about 12"
long. All a silencer does is slow down the noise as the powder
pressure wave exits the barrel. A 223 for example..doesnt have a real
big bubble of gas when it exits the barrel. Just a high pressure one

And at 50 yrds..there isnt much of a crack. However there is
significant noise as the targets melon explodes. Like dropping a
watermellon from a 3rd story window. But oddly enough...it doesnt
echo much.

science is often wierd.

Go on YouTube and watch the size of the bubble as they shoot guns
underwater. The bubble of gas is surprisingly small.

Groovy, mon. Wow, the bypass from a wheel gun v. auto is amazing.
Half the velocity is lost, isn't it?

Not half..perhaps 5% at most. Vortex physics are beyond
me...but...thats the estimate.

In that case, it must be the losses in activating the slide which make
up the difference. The gas bubble at the barrel/cylinder was equal to
that at the muzzle on the revolver.

No..thats "recoil" operated , with very few self loading pistols being
gas operated.

We agree, then. I never said I thought the autoloader was gas
operated, as some rifles are.


On the Dan Wesson revolvers..where you could adjust the barrel gap..it
didnt make a big deal of difference...neasured in FPS..its
surprisingly small.

I don't have any experience with reloading handgun ammo, but do
reloaders use faster-burning and/or more powerful powder for wheel
ammo than that which is made for autos?

Nope. G

Well..thats not completely true, but largely similar or the same
powders are used in both revolvers and self loaders.

OK, so the mechanical losses of operating the slide roughly equal the
loss of gases in the revolver, giving them very similar bullet
velocities.

Actually...there are few "mechanical losses" in a self loader, recoil
operated weapon. Recoil is simply used in a more complex fashion in a
self loader. Self loaders can be considered more complex (they are)
and are more along the lines of Rube Goldberg devices in operation,
compared to revolvers.
