Let's play a game (from 1963) #2 w/answer

[Catt57]

The rules are simple.

There are 5 scenarios. I'll post 1 scenario each day in it's own thread. Some time between 24-48 hours later I will post the answer as provided by the article.

Read the scenario and then explain how it would be possible for this to happen.

This might be a little harder then the first one.

Edit:
For anyone that may find these posts in the future, here are links to all 5 question and answer threads.

The bolt face wasn't cut deep enough, and bolt acted like a firing pin around the outer edge of the casing.

Passing over the ejector when the bolt slammed shut. Always load from the magazine.

I can see where both of the previous posts could cause the gun to fire.
I'm thinking chamber still has oil and not allowing cartridge to fully seat allowing the bolt face to hammer the rim of the cartridge.

I think I'm guessing something similar to this.
As the bolt moved forward, the edge of the extractor didn't pass over the rim of the Rimfire cartridge as it was intended to do.
The front of the extractor happened to be angled *just so* and acted like a firing pin, igniting the priming compound in the rim.
"There was absolutely no firing pin mark on [the cartridge case]," the guy wrote. Wonder if there was some kind of mark from the extractor?

Since the article stated there was no firing pin mark and doesn't say if there was any mark , it makes one assume there was no visible mark. We all know what assume means.

The correct answer is probably the ejector acted like a firing pin since it wasn't loaded from a magazine.

But it makes me wonder about the old bolt single shots that didn't have a magazine to draw a cartridge from.
Would the same thing happened if bolt was slammed shut ?

I will give you the hint that, based on the answer provided in the article, there was no mark resembling a firing pin or extractor strike.

Did the bullet go out the barrel?

Assume that the round itself fired normally once detonated. (So yes)


I'm also not validating any previous answer as wrong or right.

Ok, how about new chamber, tight tolerance, rapid force enough to detonate primer compound in a rimfire.
