Unburned powder left in case

[9mmrevolver]

So my buddy is reloading for his 3006. When he shoots, it sometimes give a delayed shot and sometimes a squib. With the squib there is balled up unburned powder left in the case. My guess is that he need a magnum rifle primer with his powder. What are your thoughts. By the way he uses the same powder and primer in his 308 so I don't think he got a bad batch of powder.

Milsurp powder?
Wolf primers?
Case fill volume?

Some powders are harder to ignite and get a complete burn.

He's doing something wrong.

He is doing somthing wrong. What type of powder and weight of bullet is he using. Hang fires can be dirty flash holes or old powder. If he is using to lite of a bullet in the 06 it is not developing enough pressure for a complete burn. Does he have any problems with the 308.

What is he using for case lube?

[Bill Steele]

Like savageman mentioned, could be the case lube (especially if he is using a hydrocarbon based lube, bad idea). Another possibility is if he is using a wet cleaning process on his brass, not drying his cases fully will cause powder to clump and make burn less consistent (or non-existant). Finally, he might look at load density. If you go too light on a charge, depending on the powder you choose, there can be insufficient pressure for complete combustion. Some powders download better than others.

In any case, while magnum primers won't hurt anything, they are not required for a 30-06. If he switches primers, make sure he goes back to start levels and reworks his loads.

Is he double checking to make sure there is no stuck cleaning media in the flash hole?

[9mmrevolver]

It is milsurp powder.winchester primers. He uses frankford armory spray on case lube. He was leaving the cases wet until cartridge was complete but I already told him to tumble before putting powder in the case and that didn't work. I believe he's using 150gr fmj. And yes his 308 works perfect

On the rounds he is having problems with, is he using a wet process (ultrasonic or SS media tumbling) to clean the cases?

What is the mil-surp powder he is loading?

What is the load density in the problem rounds?

[9mmrevolver]

Dry corn Cobb media. I talked to him again and he is cleaning out the flash hole. So the only thing would be he needs to put more powder in it

[Rwnielsen]

I've had that happen with excess spray lube in 45acp. Balled up powder and squibs. I did it when I was first starting to reload

What powder does he think he is using and how much was he using when he had problems?

[9mmrevolver]

I'm pretty sure he was using wc846. Grain weight I'm not sure. Maybe 50-55

If he is running WC846 at 50gr, he doesn't have a load density problem.

A real head scratcher. I do remember someone posting a warning about WC846 in 30-06 and ignition problems from light firing pin strikes. Oddly enough, I think the solution to their problems were magnum primers. Although, I would be surprised if that turned out to fix your friends problem.

If you do decide to try the magnum primers, depending on the brass he is using, I think I would back down a tad from 50grs, say more like 45-46gr, definitely if you are running something like LC cases.

Good luck, if you do get it figured out, come back and tell us what it turned out to be.

Will do. Something to add to the knowledge bank huh
