How to blowup your rifle

[Pdvdh]

That's what I understood also. But I don't claim to be an expert on gilding. Google hold's the answer...
no doubt.

I think gilding CAN be a coatiing but in the case off bullet jackets it is a mixture.

Rich, I think it's just a terminology issue, every resource I can find gilding is a plating process where there is two distinct alloy layers. Even Nosler calls their copper an alloy not gilded?

See above post.

After making my own bullets for several years and using various jackets, I can say that there definitely is a difference in amount of alloy used in the copper! Swift uses pure copper and I suspect Nosler is heavy on the alloy side. The AB also puts some alloy in their lead core to slow expansion. I suspect it is so they can use a thinner jacket (at least at the nose)

Outside of charge weight and other stated variables and At the risk of sounding like a moron, is it possible there was some ice buildup in the bbl? I don't see temps below freezing but maybe once or twice a year and am no expert on cold issues at all but if it sat on the bench for a while between strings and snow or damp weather was involved could bore obstruction be at play for your pressure spike?

You could build up some condensation in the right conditions, you should see it build on the outside of the barrel at the same time. But it is possible, wet bore and chamber might cause some issues.

Here are a couple more pictures for you all.

This mark on the bolt has been on there since day one

Not the one in the bottom pic I hope?

I shoot in weather ranging from +30C down to -20C and have never seen condensation outside the barrel. I am doubtful that there was some ice in there unless it was jammed into a snowbank.

The gouge / scratch in the bolt that is in the bottom picture in post #78 has been on the bolt since I picked up the rifle.

True. The air is very very dry at -10. the moisture is actually frozen out of the air. Now, if the OP breathed on the bolt or cartridge or something. the moisture in his warm breath probably would have condensed and frozen on the cold metal in a heartbeat.

We get into adversarial threads at times, that stem from one group having catastrophic results, and another group routinely having no problems

Darn. You mean I shouldn't take a poke at Fed 215 primers?

Only time I ever heard of a bolt hitting the shooter's skull. The guy survived, without too much permanent damage.

Nope. There is photo documentation of a bolt stocking out the back of a dead guys head.
