Guys, you're still discussing media in the flash holes and the answer was in post #7.

Yep, the first of these loads are already downrange. Even if I get different media, I don't have to check the flash holes one-by-one anymore. Worth $20, and I have about 10 lbs of the current media left to work through.
Since when has that been a reason to end a thread in this joint? Let it run.

Who said anything about ending the thread.
First, this is not a "joint". Have a little more respect for THR.
Second, are you trying to put yourself in as a self appointed mod?

OK, I've got a piece of media stuck in the flash hole in a cartridge case.
Question is what does it do?
After all the 209 shotgun primers are closed, that is covered.
What happens when H110 flows into the flash hole and primer of a case? We all know that H110 will flow better than water if you spill some on the bench/floor.
So what does that piece of media of to the case or load, how does it react when shooting?????

An hour to clear the flash holes? How many rounds are you talking about? I use my Lee trimmer case length gauge to knock it out, it only takes a couple seconds per case, no big deal. But again, how many pieces of brass are you dealing with?
I just tumbled 500 pieces of bottle necks a few days ago in batches of 100, and each batch of 100 only took me about 5 minutes to clear the flash holes.

Well, perhaps I exaggerate a bit and it only seems like an hour.
I do between 100-200 at a time. It is just a very unsatisfying and tedious part of brass prep. I enjoy shooting and playing with my kids on my time off, and anything that I can automate that isn't fun to do gets me excited.
Not trying to be a mod...just making a little joke about how long winded we can be. It's funny how threads here can wander around. I posted elsewhere about a round count, and it moved into spreadsheets.
No need to take offense.

Good question. I don't think anybody knows for sure.
It may do nothing at all and just get blown into the case to no ill effect.
It may prevent ignition of powder causing a hangfire or misfire. I think this is unlikely, but with hunting ammo, match ammo, or anything I might end up using for self defense, that is a risk I don't want to take. Misfires are annoying, but hangfires are dangerous.
Most likely is that it slightly changes the flow of the primer gasses and alter the consistency of ignition, changing velocity and affecting accuracy. It might act like a flash hole burr in this respect.
You would have to compare a batch with blocked holes to one without in an accurate rifle and a controlled setting to figure it out. It's easier for me to just poke them out of the hole with a $20 die than to do the experiment.
Another good question. As long as it isn't stuck in there it just gets blown back into the case. There is probably always some powder in the flash hole.
I did have a batch of 30-06 rounds with some extreme hangfires up to 90 seconds. I pulled the remaining rounds apart and all that I could find in a few of the cases were some 4895 powder granules wedged firmly in the flash hole.
I think this was from vibratory tumbling the loaded rounds to clean off the lube.
My hypothesis is that they caused a misfire, but the stuck grains closest to the primers lit and acted like a fuse. Once the main charge got lit...bang!
No way to prove this, but the powder was dry, primers were reused, and other than that batch, no other issues arose from the rest of the powder or primers from the same bottle/box.

From a mis fire or hang fire stand point, I always clear my flash holes. At present, and after more than 30 yrs. of reloading, I have experienced exactly zero of either, so I'm not going to leave anything to chance in that respect.
As for powder becoming an obstruction, I don't really understand the risk there? I've thought about it, but because powder ignites, I always figured that it can't effectively become an obstruction?
