One of my .308 cases keeps over flowing with powder???

[Chiquita]

I was filling powder in my 17 times fired Starline cases and things were going great. Except, one of the cases kept over flowing with powder.

WTH??? I tried it again, over flowed. Put it aside for the last case, tried it again, it over flowed. Seriously???

I have been known to make mistakes, maybe a 6 mm case got mixed. Nope that is not the issue. Left over powder from the last firing session?

Due to the head scratcher, my head started to bleed. I brought out the borescope hoping to see what it looks like on the inside.

Looks like a bug of some type, maybe June bug.

So far I haven’t had a bug/ beetle in a cartridge case that I know of,but I have had a tiny spider in the drop tube of my powder thrower,which didn’t help.

This is why one piece of Lapua 6br brass was so heavy.

Had my share of overflowing cases thru the years. The usual cause is an insect called a "mud dobber." Seems they'll find something with a hole in it about the diameter of a pen to build in.

Empty shell cases left in the shop fills the bill, but so doesn't string trimmer exhausts, oxy-acetylene regulator vent holes, chainsaw exhausts, etc. The mud is very hard and difficult to remove, so you really have to really get after it to clean it out. The oxygen regulator was ruined and had to be rebuilt. Grrrr!

Years ago, I had a bug who decided to take up residence in the drop tube of my powder measure.

After investigating, I found the critter and cleared the tube. Since then, I place a cap on the end of the drop tube when the measure is idle to prevent recurrence. If you reload long enough you see just about every crazy thing that can go wrong. However, a bug in the case is a new one for me. Probably another thing to add to the check list.

I had a friend who after years of leaving his rifle in storage, found a spider who had built a nest inside the barrel. Fortunately, he ran a cleaning rod down the bore before shooting it. It's probably good to get into the habit of visually checking the bore for obstructions before shooting it each time.

Wasn't what I thought when told that someone caught the "reloading bug"...

Why did you think everyone is always yammering about 'bug holes'?

 

[TAJ45]

^^^^^ Luv it.

Why mud daubers are on spider patrol | UC Agriculture and Natural Resources

UC Cooperative Extension advisors are on the front line and get the most interesting questions from our community. Someone brought some wasps into our office, and was worried they were invading her home, and wondered how to get rid of them.

We have a few varieties here in KY, and if brass is left very long on the peripheries of our ranges, they soon get plugged up with mud and I know a Spider met it’s doom to feed the next generation of these creatures. Seems they like Black Widows as well; all the better.

Except, one of the cases kept over flowing with powder.

Head scratcher for me was that you didn't inspect the case before you started or at least after the first overload.
You should thoroughly inspect your cases before you seat your primers and again before you drop the powder. Hopefully, this will never happen again but, it's a good habit to get into.
Don't forget, your goal is always to make the best cartridge there is available.

new one on me. i had a bullet blow up in a 22-250 barrel. dont know why — mabie a bug was in there!!

 

[Albany Mountain]

Yep, had flies in mine before.

We have a bug here everyone calls a stink bug. They are horrible and can get everywhere.
Front loading washing machine. Glass double pane front door. Stink bug between the two layers! Couldn’t stand seeing this bug and paid to have a repairman come and the bug out. They can get anywhere. People here say they come from China inside the cardboard boxes. I’ll go with that. Plus they are alive (though very few) through the winter regardless of temperature. Don’t crush them with your fingers no matter how enjoyable, that stink will be on your hand for two days!

Mud Dauber wasp… Oh yes!!
Spent 10 frustrating minutes trying to get a wipper snipper going only to find on more careful inspection that the exhaust pipe was plugged ….
Cleaned it all out with a bottle brush, then a shot of “Start Ya Bastard” {Yes, that is a legitimate name of a starting spray} and presto! Ran like it should.
I wrap a plastic bag around the motors of any equipment that gets stored in the garage and that has solved the problem… Never have a problem with the brass as it is always in the house.
