You'll also find with barrel breaks you can shoot through it with 10-15 rounds, 95% of the time. A true break in the breach and you'll be flinging paint every which way possible until you really clean everything out.
Sort of. The ball gets clipped and weakens but otherwise rolls down and loads just fine. Then when fired as the shell begins to expand from the pressure, that shell now collapses at some point down the barrel. Depending on how bad the fracture was. This isn't always the case........some paint is just so brittle the mere expansion from the air blast IS enough to burst a ball which is why you should always use a decent overbore on cold brittle paint(it gives the ball more room for expansion). If you're breaking paint even when you one ball....then it's probably the air blast causing the barrel breaks. If it happens only when your shooting strings, it's probably clipping.
Either way lowering your operating pressure and LPR is the same cure for both problems. Regardless of your gun type.
Now if your paint is so brittle even an air blast at your lowest pressure will break the balls....then you need to leave it open to soften up, or warm it up. Those are your only two choices at that point.
