Today I fired reloads of unknown origin.  Yes, not the most brilliant of moves, but they were free inherited from a friend who inherited...   They shot OK, with no obvious pressure signs.  But on two rounds, something odd happened.  They cycled into the chamber fine, but when I pulled the trigger, it went "click".  So I extracted the unfired rounds- which took a bit of force.  Upon inspection, there was no strike upon the primer.  So I re-chambered them, and they fired fine.  

What would cause this?  The gun went "click", so how come the firing pin didn't strike the primers on the first go-around?

The cases may have been a smidge oversize and not allowed the gun to return completely into battery.   On many guns, if you are out of battery by 1/16" or so, the hammer (or striker) will trip, and will go CLICK, but the energy is spent nudging the slide home (may not get there) instead of transfered to the primer.

With the hard extraction,, shoulder not bumped back far enough.
The second time the rifle had sized the case back far enough to properly fire them.

Thanks for the quick replies.  So now I'm nervous, is there risk of out of battery discharge here?

If the locking lugs don't engage all the way, it won't fire.

Keep in mind when shooting "handloads of unknown origin"––they may have become available because the guy who loaded them killed himself shooting his handloads in a gun that blew up.

I almost spit out my dip laughing at that.  True is the best kind of funny.  I once went to a garage sale and a lady was trying to sell her dead husband's hand loads.  She told me how much time he spent reloading and how great and accurate they would be.  I bought the entire lot at a cheap price and never told her she was probably breaking a law and opening up herself to huge liability issues.  I just took them, thanked her for the deal and slowly worked at pulling every bullet to recycle the brass for my loads. She was a nice old woman whose husband just passed away.  No need to worry her about everything else or leave them for someone else to make a problem for her.

If you didn't load them yourself, don't fire them.

You were lucky sir.

I wouldn't shoot them, I would pull them and use the components.  But, if you want to, I'd put them all in a case gauge as it sounds like they were not sized correctly.
