Re: Depriming cases with unfired primers
I can't understand why there would be primed cases in the "brass on the ground" at the range.
I wouldn't toss 'em. Load 'em in the gun, pop the primer, and then treat like "fired brass".
As to the ones with a firing pin strike but not fired - if they haven't gone off now, they aren't going to go off. Pull the bullet, dump the powder (do it in the yard - it is great fertilizer), treat as "fired brass" - deprime and reload.
