IMR 4007 SSC Loads
- Thread starter 222remx4
- Start date
IMR 4007 was recalled and not in production now. I believe the warming was that the powder degraded and was corrosive. I checked the Hodgdon website re: the warning but could not find it. That said it is definitely not a part of the IMR product line.
I have attached some Barnes data for it. Any previous gen manuals ah of KD have data for it.

Thank you . Murray
I still have a few lbs of this powder that I am using. If your powder is still good then store it in the freezer. As an experiment I stored a part can in the garage a few years ago during the summer and it went bad. The stuff in the freezer is still as fresh as new. I also keep any ammo that is loaded with 4007 in the freezer too just to be on the safe side. It's great powder provided it doesn't go bad and I'll miss it when it's all gone.
There never was a lot of data for this powder but the 2009 Hodgdon guide has some data....

There were some claims made that IMR4007SSC powder was “heating up” in the container as a byproduct of an unstable chemical reaction…possibly part of the same reaction as the “degradation and corrosion” others talked about.
4007 SSC has been my go-to powder for my Cooper JG 7mm-08. I have a very accurate and reasonably fast deer load (using 140gr Nolser BT or AB’s) around 2800’/sec. Been using it for years.
I had 4 lbs to begin with but am now down to only 1-1/4 lbs remaining. Just to be clear, I’ve never had any issues with the powder, myself. My remaining powder seems fine to me…no heating or acrid smells from the can. Out of an abundance of caution, I’ve been storing in a separate steel ammo can in an unheated garden shed. Storage in a deep freeze seems like a solid idea…maybe come spring.
That said, I intend to use it up very soon and be done with it.

Hello. I have mine stored in an outside fo the better part of 10 years with no issues. I started using it in a 1-8 twist 22-250 with 80.5 gr Bergers . I had to pressure issues and backed the load down . I switched to H-5831 sc . Does well. Sweet rifle made up by Sean Desbean when he was gun smithing. Might give this powder a go again. Working on a plicking load 126.5 gr bullet in 303 British. Tried it out and I'm settled on a load to play with. Be well thanks for your reply to my post .
I had 4lbs and then many years later, found out about the recall. It appears to have degraded a lot over time, and isn’t providing the velocity it should. So it’s definitely changing.
I contacted Hodgdon and they sent me a waiver to sign and with photos of the powder, and a promise to destroy it, they sent me a cheque for what I had.
Reach out to them.
