This is good advice. Put enough Kroil or PBblaster down the barrel to submerge the fired case, let it sit over night, then try again to extract the casing, either pogo or cleaning rod.
This. This works great.
I believe I bought mine from Brownell’s.
This. Throw in a freezer for a few hours then try again. While it works best with brass cases (brass and steel gain retain cold differently) we've unstuck many pew pew this way.. Good luck
Well score one for PSA for going above and beyond.
Part of the reason they're so successful even with a reputation for shipping the odd lemon is that they've been excellent at fixing issues that some companies would write off as your problem. They're not quite Hi Point yet for warranty work, but they're bloody close.
Chamber tolerance is dictated by the finish reamer. If the chamber tolerance is loose, the blowby should be worse.
I've never understood why blowing crud directly into the receiver seemed like a good idea lol. Seems to work though.
It actually doesn't. It get routed inside the bolt carrier to push against the gas rings and then is vented to atmosphere once the bolt/gas rings have traveled back enough to clear the vents in the side of the BC. Some fouling occurs when the gas key seperates from the gas tube but the internal pressure of the BC has diminished rapidly at that point.
Don't ruin a good gripe with your technical exactitude sir! It's a flimsy Mattel gun made out of beer cans and recycled soda bottles and it will never catch on.
Chamber gaging would reveal this to be true or not. I am of the opinion that a loose chamber would operate even dirtier and it would allow pressure to bleed back instead of pushing the bullet out. Muzzle velocity would drop. Pressure drop in the chamber would also lessen the "push" of the case against the chamber wall.
