Verdigris and storage query
About 10 years ago I thought I was coming into an Enfield. I was so sure of it that I went ahead and loaded some ammo for it fully expecting to shoot it all within a year. Well, it fell through, so I simply stored the .303 on the shelf. I have since come into an Enfield and planned to shoot it this upcoming weekend, so I went to load some onto clips for the trek. I noticed verdigris where the bullet meets the case...BUT only on one particular load. I had used two different powders ten years ago in hopes of proving one load better than the other. I inspected all of the ammo and found that the IMR 4895 ammo had no verdigris. Whereas, the VV N140 loaded ammo had the verdigris on about 25% of the loaded ammo. All my powders came from Powder Valley, so I doubt one was much older than the other (but not sure). NOTE: the two different loads were loaded within a couple weeks of each other in 2011. They used the same cases, primers and bullets. The only varying factor was the powder choice. They were even stored in the same MTM Case Gard ammo box the entire time together. Has someone come across this? And should I reevaluate using Vihtavuori powders?
