Supposedly a Revolver Looses alot of energy from the chamber barrel gap according to
I read a Forum Post on a Google Result page a couple of weeks ago about a guy claiming you loose a lot propellant gases/energy. On a Revolver through the gap between the Chamber and the Barrel. He claims that therefore a Bullet fired from any revolver would be a really week round fired. WHAT HOW STUPID IS THIS GUY TO EVEN MAKE SUCH A OUTRAGEOUS CLAIM.
I just wanted to get your take on this?????
I mean the amount of escaping propellant gasses/energy from the gap between the chamber and barrel is so microscopic. That it is not gonna make a difference in the power behind the bullet.
Then again you have people who don't believe that the trip to the moon really happened.

The fact is, it is correct. You lose pressure through the gap. Just not enough to matter a hell of a lot.
The Nagant pistol addressed just that issue. The cylinder moved forward and the brass projected into the forcing cone to make a "gas seal" revolver. The pistol was not copied because it was a non-issue.

Yes, there is a loss of gas at the cylinder gap.
See the flash?
That's why you don't want your hand THERE. But as said, the revolver was designed around that. Two identical .38 Specials- one fired in a revolver, one fired in single shot pistol, such as a Contender, the single WILL get more energy.
The comment is rather boneheaded, since I fail to see .460s, 500 S&Ws as a "weak" cartridge.
BTW, I notice there is a measurable space between the cylinder rings and cylinder walls in the engine of my truck. Using his logic, that will run only poorly and weakly.

Yeah, you lose a little because of the gap---but not much---I wouldn't worry about it---revolvers have been laying people and animals low since about 1873---it's not perfect, but it works!

I'd rather my own son see me die on my feet as a free man, than watch him go, broken, into slavery.

Yeah the energy loss is minuscule. I think something like 10 or 15 fps of MV, if it's even that much. Run towards the target while firing to make up for that.

And C3 knows about Sam Colt's patent because he was in the reviewing office at the time.

Thats why when you see some velocities listed "from a vented barrel" it is supposed to mimic a revolver velocity.

I have a load for my .44 mag that is 265 grains coming out at about 1400 fps. I know this because I used my chronograph to test it. That is enough velocity for me. There has to be some pressure loss between the cylinder and barrel but as said above, not enough to be overly concerned about.
