like Tom said, i wouldnt fire them...i would dispose of them somehow..but would make sure noone could fire them...
just no telling whats actually in there...could be perfectly fine...could blow you and your rifle to pieces..
just not worth the risk IMO...
as a rule of thumb NEVER fire anyone elses reloads...ever...
only exception might be is if a VERY good friend that knows his stuff loads up some pretty light generic type loads for you...or if he actually works up a load for Y O U R rifle...but, you gotta trust him and his loads...
personally, i will likely never load for anyone..i dont wanna hear it when they get the only bad primer in the brick...and dont want blamed for nothing..
only exception might be dad..i might work up loads for his 2 hunting rifles if he wants me to and load him 50rds for each rifle or something..then he's got an accurate load with good bullets and doesnt have to worry about ammo for a real long time..
i definitely strongly advise against firing those loads or letting anyone else fire them...ever..they need disposed of...
