Talking about OLD powder!
I know we have had discussions in the past about storing powder and using old powder. Well I've been working on loads for my wife's elk rifle lately and it's been giving me fits. Best it was doing was in the 4 to 5 moa area no matter what. Was driving me nuts. BTW it's a Ruger 77 Mark II in 7mm WSM. Well was loading using both IMR 4350 and H4895 that were probably no more than 2 years old and it wasn't working. So I dug down in my reloading bench and pulled out the very old cans of IMR 4064 and 4320
These are at least 30+ years old if not 40. Well needless to say they helped solve some of my problems. The 4064 did the best and the groups were down to 1.75 moa or there abouts
So I guess it goes to show that powder properly stored will last for years and can even out perform newer powders.
