Guys

So I loaded some .223 with 24 grains of W-748, 69 Sierra Matchkings, and PMC primers.  My AR is at the shop so I took out a H & R break action I just bought and tried to get it sighted in.  Needless to say it was one of those days on the range you would like to forget.  

I started off with some Hornandy factory ammo to get it on paper.  After I got it on paper, I tried my reloads and it seemed like there was a slight pause between the time the hammer fell and the shot fired.  I am new to reloading so I try to pay very close attention to anything that may be "off" when I am shooting my reloads

After loading the rounds I ran them into a Lee Factory Crimp die.  I was wondering if it is possible to crimp the rounds too tight to cause this pause.  Or am I just imagining things and there was no pause.  Granted this was a new rifle and I am not used to shooting it.  Something just sounded different between the factory ammo and my reloads.  Any thoughts???  Thanks everyone.

Any suggestions fellas.  I did some reading on the Lee Factory Crimp and they claim you can't crimp them too tight.  I hope I am just imaging things because I was told this die was the "cats meow"

Are the PMC primers "magnum" small rifle?
How is the headspace on the H&R ,are you over "re-sizing"?

Something is not lighting the fire properly.

Is the appearance of the firing pin dimple in the fired PMCs any different than the Hornady factory stuff (width, depth, etc.)?  My first guess is you are imagining the "delay".

Crimp won't affect delay

Are your primers seated slightly below flush?

Could it be weak primers? After all Win 748 does need a stronger, hotter primer.

Get someone else to observe while you shoot these loads again.

Also load a few rounds with a different primer to determine whether the loads act different.

I'll bet on perception, but you never know.  

The only hang fire I've ever had with a muzzle loader went well over a minute and the gun fired just about the time I got bored with waiting.  That won't ever happen again.  I was surprised by both events, the hang fire and the long delay.  The cause was a change in patch lube from spit to a commercial product.

get yer reloads and the factory ammo....mix them all together, grab a few, preferebly without looking and start loading a mag.  Start shooting until you think it was delayed, then examine which round it was....this should prove if it is just in your head or actually happening.

If it is a true hang fire, I'd put my money on a bit of tumbling media in the flash hole.

You've got some good advice regarding testing for hangfire's already.  

I will say, hang-fires really can happen.  Back in the early 90's I recieved about 2k casings from a friend of a friend.  Most of it was de-primed, but around 200 of them still had unfired primers in them.  Woohoo!!  They were just primers - what could go wrong?  .....



So I loaded them up.  And almost every one of them had a 2 second hangfire!  I always assumed it was some kind of oil or whatever that got in there.  But the post above that it's tumbling media is an interesting one - hadn't thought of that!  

I will say one thing, they were great practice rounds for follow-through!  [Shudder], today I'd probably just pull them all.

I guess my point on that is I never experienced a short duration hang fire.  In my limited experience, they were all at least a second or so.
