* Not my gun, Forcefed had it with him on one of our range trips

[Spike]

Oh hell yea!

[VikesFan1]

Nice. Reminds me of my old AMT .30. The thirty probably wasn't that dirty though.

[forcefed]

Theres my pistol

[Pat Cannon]

Cool. I was just reading up on muzzle flashes. Apparently only about 30% of the chemical energy of the cartridge gets converted to kinetic energy in the bullet. The rest is waste, or as we call it, fun. And maybe a touch of permanent hearing loss.

Interesting in the top frame how the gap behind the cylinder lights up. I guess the brass doesn't seal the chamber completely enough (or fast enough?) to stop all the flame.

Also,

Oh hell yea!

What he said!

And hi to Mr. Forcefed from a fellow Ruger fan.

I thought nearly all revolvers had a gap between the cylinder and barrel? (except for the Russian Nagant)

I will post some of these from a 460 S&W...the flames that come out of that are insane, and a lot of them come out between the cylinder & barrel.

I was kinda surprised how dirty the frame behind the cylinder gets on my j frame. This would explain that.

Cool pics.

Well yeah, of course there's a gap at the front, I just never noticed flame back at the recoil shield before.

Speaking of Nagants....


Don't think this was their intent but it does actually seal the gap nicely.

Actually, I think the glow surrounding the cylinder in the first picture is blowback from the cylinder gap. If the cartridge doesn't seal the chamber, they you get dirty, sooty cases, but with hot loads like that they normally come out nearly untarnished and shiny, which proves there was no break in the case/cylinder seal. If the cases WERE leaking, then they would look like the frame surrounding the firing pin.

well sinse this turned into a fireball picture thread





Yes I'm aware that is the smallest one posted yet (but if you look close you can see the bullet!)

I am also aware that the wife is displaying an awful grip

[ComradeBurg]

If the bullet doesn't stop them the giant fireball giving second degree burns will!

Hence why you have to put grease over the ball in cap & ball revolvers to prevent chain fires.
