Thread: Another Trip to the Range

There are two tins of IMR4831 in the garage that were given to me. Packed in 1987 and unused there was rust on the outside and inside of the cans and the powder had clumped. It will be spread under the trees. Also in my powder cabinet there is a part tin of IMR4064 packed 10 years earlier which is fine. Recent chronographing shows velocity right on the button. The 4831 was likely stored in a tin shed sitting on a dwang (nog for SI I believe) hard against the tin cladding.
GPM.

Smokey Jason also gave me a small amount of IMR4831.
Must be at least 35 years old. Tested that in the 30.06 too. It's fine. I'll finish off the tin by loading the 70 or so 150gr bullets that came in the package.

If it looks OK, smells OK, little or no rust, it'll generally be ok.
