Pull Trigger--Click no Bang

[HTSmith]

So this is a 6Dasher on Kelbly Panda action. I often fire form a few rounds as foulers before I start a shooting session. I form a false shoulder and still jam bullets quite a bit. This has worked well for me for a bunch of cases with no misfires. This morning I goofed up and seated my bullets toooo long. It was quite a chore to close the bolt. Pull the trigger and click. Wait a bit and pull the round and it looked like a good primer hit. Put that round back in and tried again--click again. Tried another fire forming round and click again.

Then I proceed to shoot my 15 test rounds in multi fired brass with the same primers with no issues. Actually found a humdinger of a load (I think).

Then I go home and pull the bullets on my three fireforming loads and dump the powder. Chambered up the one primed empty with no dent and pull the trigger and bang. Then I put one of the empty cases in my gun with a previously dented primer and bang that primer goes.

Sorry for the long story but I'm buffaloed. So what do you think is going on?

Thanks for any help.

BTW Brand new firing pin spring

So one of three rds meant for fire forming had NO pin strike on primer, 2 had pin strikes on primer? And than primer pop after bullet/ powder pulled. Excessive headspace, bullet held the rd in the chamber off the bolt face, resulting in poor or no pin strike??? Did you have the muzzle up when you tried the primed case at home?

I had three fire forming rounds. I tried two which did not fire and didn’t pull the trigger on the third. Sans powder and bullet they all fired. False shoulder takes care of headspace. Thanks for help

That's puzzling. Tagging in to see if someone knows what's going on.

seated my bullets toooo long.

The rounds chambered on the long bullet. The firing pin strike seated the bullets deeper, shorter COL. When the bullet moves , the pin energy is absorbed. Misfire.

The false shoulder was not making contact.

Hmmm...how is it that when I pulled the bullets from the cases that didn't fire, those same empty primed cases fired just fine?

same empty primed cases fired

The false shoulder made contact. No bullet to be seated deeper & absorb the energy.

Depending on the type of extractor, the case can move forward , till it makes contact with the false shoulder or the extractor stops case movement early.

A Savage extractor will hold the case & fire the primer with no shoulder on the empty case. 223.

The head to datum may get shorter when the pin hits a dead/defective primer, by .006"

Muzzle up empty case stays against bolt face, enough for primer ignition.

Muzzle was down. Thanks for help

I don’t think the primers just mysteriously started working.

I think maybe you had some debris inside the bolt body that was knocked loose in your failed attempts. Disassemble and throughly clean the bolt body and firing pin.

You may not even see it fall out. Doesn’t take much.
