Hi all, when I was young my dad bought a reloading press and we dabbled in reloading casually together. That was about 20 years ago and I just recently got the itch to pull everything back out again and blow the dust off. He had a few pounds of H335 and a couple thousand cci 450 primers from way back then. I have read how people say powder and primers will last about forever if stored correctly. Maybe my dads was not. I loaded 10 rounds with 22 grains of H335 this afternoon and went outside to see if they shot. I got 2 duds (both with good primer strikes) and my velocities were all over the place every shot from 2300-2700. The last round did not lock the bolt open. I am aware that I am at about a 0 in terms of experience so feel free to nock me if I am doing something wrong but could it be that the powder or primers are bad and I should just dispose of them and buy new components? Thank you for your advice
