I had a mishap at the range today. I had loaded some 7 mag. Out of a 3/4 empty 8 lb of IMR 4831. And now have a gun locked up bolt will not even open. I am not new to this and very careful with my powder. I finished shooting my other guns and headed for home. I took a couple of the other rounds apart and found a 2nd type of powder. A fraction of the size of 4831 and tube shaped with a hole thru it. First thing I did was compare all my other powder and no such luck. I emptied the rest of the 8 lb and found about 15 percent of the powder is the smaller. My powder thrower is not clear so I didn’t pay any attention. I have sent an email off to IMR with the lot number and discrption of the problem. I know they wouldn’t do anything I would just like the powder identified. This one is going to be costly. Can anyone help me with identifying the powder. I have done internet searches to no avail.

Do you have any opened cans of powder that look like that?
The powder measure got dumped back into the wrong can?

It doesn't really matter what powder it is - dispose of that jug of 4831.

Avoid brute force on the bolt handle trying to open it. To get the rifle open, it might be easier to remove the barrel first, as long as the action doesn't have an extractor that engages a cut in the breechface. Remington, Savage, some Winchester, the barrel can turn off with the bolt closed. Have to use an external action wrench, of course.
 
Problem is I am very careful and have never had this type of powder in my shop. I compared all of my powder on hand and nothing even remotely close to this.
 
Might be a problem with IMR lot, I would guess he want to know what powder it's to be able to prove he doesn't have some and get IMR to foot the bill for their mistake.

Is this from Higginson powder? They repackage their 8lb box from drums so might not be from IMR directly.

The H4350 I bought was from a jug and the H1000 was a repackaged.

Looks like they didnt clean equipment properly between running two different powders on a packaging line.

this could be the culprit. Visually the small powder kernels resemble SR 4759 (been "discontinued" for a # of yrs. but you state it is an "old container) which would "pressure-up" a large volume rifle charge considerably I think.
 
Did you buy the jug of powder new? I picked up a used 8lbs jug of longshot this year and when I got it home it clearly had 700x mixed in it. I was lucky and the guy took it back. I will never buy open powder again. I was also lucky I didn’t run it through anything.

If you look on AOO there is more to this thread.
I would assume the OP was tired of people be littleing him on here. Which seems to happen lots. Thats the main reason I post very little.
It's great to know that you have never made a mistake or your way smarter than everyone else. And in reality the OP never made a mistake, he did things the way most of us would have.

The fact of ths is if people would read before they typed. OP does not have powder like this on his bench and never has had.
It was from a new 8 pound jug he purchased. When he opened it he gave half to his buddy. And its easy to see why the smaller kernels were at the bottom.

He has also contacted the manufacturer, who is very concerned about this, is sending labels to have it returned, and is not the only case of this out there, and could be 500 pounds of powder affected.

So this was a great post for information and am very glad the OP put this on here.
I am also very careful on powders I have on my bench, I have several scales as I load lots of different powders. All of my powder containers are beside the scales till they are cleaned up.
I have always used auto scales, and I am not sure you would have been able to see the powder that was mixed. I don't usually examine the powder every time I put it into the funnel. I am more concerned with it being charged to the exact kernel.

Thank you 50 calcrazy for posting this information for us. It is great information, and I hope the powder company takes care of you.
 
The national forensic centre is a good place to try to ID the powder(definitely faster burning, maybe 4198?). A friend of mine locked up a savage .270. We tapped a brass rod from the muzzle, simultaneously lifting bolt with 15" piece of aluminum tube. No damage whatsoever.
