Extractor Dirt

I have heard that dirt undernear the extractor star can cause
a revolver to bind. Is that an issue? Why is this the case?
 
Yes. Usually it is unburned powder and other residue from firing. Most often caused by improper ejection of the spent cases. If the muzzle is elevated and the extractor is actuated right smartly, the cases will clear and take the crud with them. If it is done with muzzle level or pointed down, easy to get stuff trapped under the star.

Very much an issue; especially for handloader's who use
the slower burning powder's, such as 2400 and H-110.
The problem arise's when unburned powder accumulate's
underneath the star. If it is not cleaned out, it can build
up enough to stop a revolver from functioning properly.
I always carry an old toothbrush in my range bag, just
for cleaning the dirt and debris away from the star.

Thanks for the replies.

How does ejecting the brass with the muzzle "up" clear
dirt under the star.

It mostly stays in the cases as they come out. Bouncin em out with the muzzle down allows the unburned crud to fall into the action.

In my experience the problem is worst with .22 revolvers. However, regardless of caliber, it's important to keep the area under the extractor oil-free. Any oil under there will catch and trap firing residue and cause it to accumulate significantly faster than if the area were dry.
