Taking out a squib, the explosive way.

I am thinking of new way to get a squib out. Well, at least I have not heard of anyone doing this yet.

Why not charge a case, without a projectile. Then, carefully load and fire it through the squibbed barrel to get the projectile out?

I figure, it will be lower pressure than expected, since you've got the equivalent of a very long COAL, so use a decent powder charge. Of course, you need to be a reloader to do this.

I must be missing something obvious here...
 
Yes I think you're right. I'm my case, I'm talking about a squib that is just past the case mouth. Probably about 1" from the case mouth.
 
Oh god, this is not turning out too well lol.

Alright, bad idea, just wanted to know exactly how bad it was....

Likewise, in a muzzle loader, they say to ensure the projectile is seated firmly onto the powder charge, with no air gaps...

How much is liability warning, and how much is real... who knows.
 
I'd be interested in hearing how Ganderite does it but one concern would be slumping of the powder and flash ignition of across too large a surface area. This could cause a pressure spike but would be easily avoided by using some kind of wad material.
 
When it happens, I just pull the bullet from the next round and dump out about half the powder. Then I chamber the case, keeping muzzle up, so as not to spill the powder. When I pull the trigger, I hear either a small bang (bullet gone)or a phffft - bullet still stck. Then I repeat, with more powder. Have never damaged anything.
 
In total ignorance of the real downside I would be concerned that:

- Some powders show strange characteristics at charges below a certain minimum.
- Pressure waves moving up and down the barrel could meet in a way that they reinforce one another and cause a local bulge.
- The ramping up of pressure from the burning powder and the onset of bullet motion are critical in determining maximum pressure since starting friction is greater than that of a body in motion. Sufficiently displaced in time and space the pressure could peak too high.

My question is why? when safer ways are so readily available?
 
I don't get it. Just dont put full powder load in... It takes a lot less pressure to just move the bullet out of the barrel then to propel it at 3000 fps like usual......
