I've had some since around 2012, sored in a cool dry basement. Anyone have issues with it getting old/stale?

TTT.

I have several cans that are 4yrs or so old and they are fine.

Same here as Bearcat74.

I bought 8 cans when it first came out and still have 6 left. I put up 100 charges in plastic vials at least 5 years ago and am still using them. They work fine, shoot to POA and kill deer.

I don't believe BH209 is hygroscopic like T-7 is. It should have the same shelf life as smokeless from what I understand...and I am still loading .270's with H4831 from WW II.

Thanks. I have some I measured out in 2012, I shot them last night and they put the holes in the paper where I wanted 'em.
