Advice needed ... bolt opens on firing!

[Peter Laidler]

We're wayyyyyyyyy off the subject now, but I believe that it'a all down to the fact that you can compress steel (and air) and it WILL react as opposed to a liquid that you cannot compress and it won't react. Get a poly bag or baloon of water, empty it of air and tie it up. Drop it onto a surface plate or something similar and see what happens. It'll just deform and lay there like a wet fart.

Get a ball, fill it with air and do the same thing. It'll bounce to a set drop to bounce ratio

Get a ball of steel, like a ball bearing (or even a hammer head, ring spanner, the harder the steel the better......) and do the same. It will bounce. Don't believe me, take a look! Once again, to a set drop to bounce ratio. This is in effect just what you are doing to the bolt when you hit the bolt head, which is attached to the bolt. If I had a 40 minute physics lesson I'd explain it better but that's about it. There is no secret or black magic there.

Forgot to say. You can easily and simply eliminate the striker spring torque theory by taking it out and firing the cocked cocking piece/striker forwards with a catapault (or something similar) contraption. Yep....... the bolt still rotates slightly.

There is a word for this physical property but I forget what it is. JM...., help!

I know Muffer thinks that I'm getting cranky but I don't suffer fools any better or worse that the rest of you. I'm wise enough to answer the questions - just so long as you don't keep changing the questions or even worse.......... I won't go on!
