Concerns 7 year old powder?

I'm pulling a barrel off a rifle and realized I've got about 200 rounds of ammo that equals a lot of Varget (30.06). Any concerns reusing powder this old particular since it's been sitting in a case? Do/can primers change the molecular integrity of the powder?
Thanks in advance.
7 year old powder is like a toyota engine with 2000 miles on it. You've got a lot more years to go on that powder.....As long as it's been kept dry it's GTG.... I'm shooting powders that are 20-25 years old with the same results as when it was new powder.
my .02 cents
 
I have some (2-300) 30-06's loaded with WW760 under 165 JSPBT. Velocity for 5 shot string was 2925 in 1983. They were stored in conditioned space in sealed cans. Checked some last month and powder looked/smelled good. Velocity was 2920 for 5 shot strings. Back in the storage cans the rest go.
-You should be good to go.
 
If primers hurt the molecular integrity of the powder the circa 1970 30-30 ammo my dad and I spent a day shooting a few years ago should have had its powder plenty violated by now haha. As @ButterBean states, "Let her eat!!!"
 
I shot 4831 powder that was bought in 1964 through the 80s and 90s and believe it or not the guy stored the powder in the hole of an old outhouse in glass jars wrapped in brown paper bags. David

That is awesome. I'd sure try pretty **** hard to find a better place than the hole of an old outhouse :) Did the retrieval process start with, "hold my feet...."?

The only consolation was the out house hadn't been used in years it was in a small town so don't know for sure when the sewer systems was built. David
