It's always a good practice to remove the boresight ......before firing ......Bang! :p

I hope they did a really good job on the bore siting... I hope they were atleast on the paper. :)

bore siting is where you aline the scope with the barrel.( IE if you imagine a strait line coming out of the barrel, that is what you aline the scope.) From there you can find tune.

didnt anyone here watch that episode of mythbusters?
they proved this as a complete myth. Gun Barrels just dont 'bannana peel' like that...
--------------------------------------------------------
Finger in a Barrel
Cartoon Myth: If you stick your finger in the barrel of a gun, the gun will explode. The shooter will be injured but you will be fine.
There was a great cartoon done for this myth that featured reinterpretations of Adam's "Am I missing an eyebrow?" quote and Jamie's "Quack, damn you" quote.
Setup
Shotgun with remote control trigger
Ballistics gel hand with a skeleton cast inside of it for rigidity. The hand was attached to Buster.
Balllistics gel bust for the shooter The bust was made from a cast of Grant.
Tory: "Coming up on MythBusters"
Kari: "Can we get Grant out of this mold?"
The Tests
Test 1 (gel hand): Buster's gel finger was stuck inside the shotgun barrel. The entire hand was blown apart with no damage to the shotgun.
Test 2 (wax hand): They used a stronger ballistic hand made of wax to plug the barrel. The wax hand was blown apart but the shotgun barrel was ballooned slightly.
At this point they declared the myth busted and moved on to trying to replicate the myth. They wanted to get a 'banana peel' result by firing the shotgun.
Test 3 (dirt): Tory stuffed the barrel of a shotgun with dirt. The end of the barrel peeled back slightly, but the shooter was fine.
Test 4 (Steel spike): They welded a steel spike into the barrel. The gun shot the spike out with only minor damage to the end of the barrel.
Test 5 (squib load): A squib load is a bullet that doesn't have enough gunpowder to exit the barrel. Jamie hammered a bullet into the end of the barrel. The end of the barrel bulged, but it didn't banana peel.
Not only was this myth busted, but MythBusters failed at even replicating the result of this myth.
mythbusted While it was cool that they ballooned the end of the barrel, it didn't explode, the hand was blown apart, and the shooter was safe.

1st myth busters are a joke.
2nd there is a huge diffrance betweena shot gun and a high powered rifle.
you really think its safe to shoot a gun with a pluged barrel. go buy a cheap used .30- 06 then got stick the barrel in the mud 6" then go fire it. report back to us.

Here's you the main difference:
I've handloaded for 20+ years, shotgun, various handgun rounds, and .308Winchester (7.62mm NATO ) rifle.
A shotgun, regardless of caliber has a maximum working pressure of 11,100 PSI.
Handguns and rifles vary, depending on when and how they were designed, examples below from my Accurate Smokeless Powder loading manual (1994):
9mm Luger (parabellum) - 33,000 PSI
.38 special ------------- 17,000 PSI
.357 Magnum ----------- 35,000 PSI
.44 Remington Magnum -- 40,000 PSI
.45ACP ----------------- 21,000 PSI
.45 Colt ---------------- 14,000 PSI (much higher in a Ruger or Thompson Center as the guns will take more than a Colt or clone)
.220 swift Rifle ---------- 54,000 PSI
.223 Remington (5.56nato)-52,000 PSI
.270 Winchester ---------52,000 PSI
.270 WEATHERBY magnum - 71,000 PSI
7mm Remington Magnum - 61,000 PSI
.30-30 Winchester ------- 42,000 PSI
.308 Winchester --------- 52,000 PSI
.30-06 Springfield -------- 60,000 PSI
.45-70 Government ------- 28,000 PSI
Most gun barrels are designed (Browning actually Proof Tests theirs) to sustain a double-pressure load without catastrophic failure.
That said, their tests ( I watched that mythbusters) was with a Manlicher Caracano rifle, 6.5mm Italian (Carcano). Only my Lyman book shows data for it, but shows no SAAMI max pressure. The loads are identical to the 6.5mm Arisaka (Japanese) in bullet weight, powder charge, and velocity, so it's pressures must be the same (or very similar), 40,000 PSI.
Perhaps on Mythbusters, the 40,000 PSI with a blockage wasn't enough in the rifle they had (it did have a "sporter" (non-"bull") barrel), but I believe the 55,000 and 60,000 PSI class rounds have much greater potential.
The photo is entirely likely genuine. Hope the shooter wasn't hurt, and is now smarter.

A shotgun barrel at about 800 FPS with a pretty large bore. That rifle was likely around 3000 FPS and prolly around a .243? Big difference there my friends... :)

Before you believe internet or television "facts" you are well advised to do your own research.

I'm sure smokin's figures are relitive to bullet weight and powder/primer combinations.
I believe Ruger is also proof tested for pressure loads also.
I have a Super Blackhawk .44 Mag ( One of the beefiest .44mags on the market) that I have loaded far beyond what Speer recomends as maximum load. as well as my Colt Python has gone far beyond max suggested load. there is a tendancy to loose accuracy with the heavier loads though, but goddamn the muzzle blast energy alone is enough to kill a bear at close range. :D
as far as the Pic goes.. how drunk does one have to be to chamber a round with the bore sight still in ? :idea: I hope the bolt stayed in and didn't shear the lock and tear the guy's face off.. geeez thats scary :eek:

Man, that shit scares me every time people do it. I sincerely hope one never opens up on you. How's the cylinder end play? Is it getting loose yet?
A friend of mine used to overload a .44 mag Ruger Redhawk, shooting silhouette steel. After a cylinder full, he couldn't eject them untill the gun cooled for a few minuites. After a few years, he re-thought this, and decided it really wasn't a bright idea, and disassembled the remaining ones and worked up a new, more sane, loading.
Yes, just about all firearms today are proof-tested to survive excess loads ONCE, they are not designed to digest that regularly. .45 ACP is one of the exceptions. The way the chamber ramp is cut from the chamber itself exposes the brass directly, and any heavy overpressure will blow the brass out, right at the top of the magazine, right down the center of the frame stocks, that you are holding on to at the moment.

The pressures I listed above are the published SAAMI maximum designed pressure for the given cartridge, regardless of parts combination. Often given loads are lower, but are not supposed to go higher as this is the maximum pressure the firearm is designed to expect to deal with in use and not suffer excess wear or damage.

I don't think I would over pressure an Italian Mannlicher-Carcano rifle or carbine. The lugs on the bolt are at the rear of the receiver instead of right behind the chamber.
