You have to watch these real close especially in the area of the sight, but the only one I can see that didn't rupture was the Blaser.

Now hasn't Blaser been taking a bunch of heat for doing just this---Rupturing? You can see it's fore end bounce but doesn't appear to rupture..

I'm a bit skeptical about these tests anybody know the source. What lab would hang a sheet of white paper up behind a work bench then clamp the barrel in a bench vise to do scientific test of a barrel.

Still very interesting

You must not have watched the VERY CLOSELY, because the Blazer ruptured as well!

They all ruptured, but the ones who made the least amount of shrapnel were all rifles which are fitted with cold hammer forged barrels. The steel in the American are mostly soft chromoly, and button rifled. The hammering of the cold hammer forged barrels makes them extremely strong! However they burst as well, but were simply not as dangerous as the button rifled soft steel of the Remington and Browing. The Browning is not an American made rifle if I'm not mistaken, but are contracted from Japan like most of the Weatherbys

Blazer's problem was not the barrels bursting, but the straight pull bolt letting go!

Nobody is trying to piss down your back just because they are American rifles or even Jap made american rifles. I thought it was informative as I have never seen tests like those although we often speak of pressure and bore obstruction dangers.

I never thought you did piss down anyone's back, American or other wise!

All I was saying was the only difference, I can see, that is common to all those with the least damage were COLD HAMMER FORGED barrels, and the ones that burst very badly were chormoly, and button rifled.

My point is the hammering process over a positive mandrel aligns the stress together making the steel very strong,and stiff,compressing the steel into a very tight mass, while the mild steel unduely miss-aligns the stress by the button being dragged thourgh the bore,and if not stress relieved,in some way, is more prone to ill effects by sudden high pressure changes, because it leaves weak spots. This test is a fine example of that fact, no matter who did the test, or where the rifles were made!

Personally I think it was a great test, and simply agrees with the opinion I've had for many years!
