I decapped hundreds of cases with live primers.
Usually when I've bought brass which was primed, but not properly stored or properly processed...once a batch of brass had different color primers...I want primers from the same batch in my ammo.
I only use salvaged/pulled primers for non-critical applications, like forming cases, or another one is, when I'm loading a large batch of pistol ammo, I always load in batches with matching HS cases, but when I get near the end of a large batch, there is always some mixed HS cases...I will use pulled primers for those and label them blasting ammo...I don't even call it plinking ammo...blasting ammo is used for testing, whether testing a gun or a new type of target or something else wear accuracy and 100% reliability isn't needed, I am much more aware of squibs and things when shooting blasting ammo as well. Lastly, I will say I have never had a Dud primer that was pulled and reused...but I expect to someday.
