Did I Load Wrong or is the Gun Broken

[Smitty79]

In the, almost, 6 years I've been reloading, I've loaded and shot around 70k rounds.   I had a squib at the 3 month point and none since.   Yesterday, I was practicing with a Shadow.   I had what I thought was a double feed.   I didn't notice a "squib" sound but had what looked like a double feed.   I have never seen a slide cycle and feed anything when I have observed squibs in others.    That batch of ammo was running fine in my P10C.   I found a bullet about a half inch into the rifling.   It required a hammer and my squib rod to get the bullet out.   This ammo was a batch I loaded last weekend.

Today, I used a different batch of ammo.    It was some I'd loaded 6 months ago.   Same brand and size of bullet.   It ran fine for 50 rounds then double feed again.   Bullet stuck in the barrel.   I finished the match with 100 rounds through my P10C (I was the only guy there shooting their carry gun).

I suspect the barrel has a problem.   But after pulling out the barrel, I don't see anything wrong.

Was this likely 2 squibs?   Boggles my mind that I could have this many in such a short time.   I'm loading on a 650.   I don't have a bullet feeder.   I think I look in every case.   I'm probably going to put in a different barrel and go slow fire 300 rounds before I trust my own ammo again.

Differently the ammo not the barrel. Sounds like a round with little to no powder both times

Absolutely more info needed. What powder and what bullets ?

[Smitty79]

Acme 147s over 3.2 gn of Titegroup.

Of the 70k you have reloaded and shot were all of them loaded on the 650?

[Wobbly]

I'm wondering if 3.2gr of TG could be position dependent. TG is fairly dense. Volume wise... that's not a lot of powder.

What's the bullet length and OAL ?
Which dies ?

50k on a 550

Wobbly,  Acme 147s at 1.13. Dillon dies.

I reload on a 550 and a T7 Redding with a Harrell's measure. I have never had a squib but have had a few that just didn't sound right when fired (9mm/45acp).

I reload in my garage and figured out it was the powder sticking due to the sweating of my measures going from warm to cold in the garage in the winter.

There's nothing wrong with the barrel (if you haven't fired another round behind a stuck bullet).  The problem is either a very light load of powder, or no powder at all.  A primer has enough power to push a bullet into the barrel, and that's what it sounds like happened. 

And yes, it's possible that you had two squibs in two different batches of ammunition.  I loaded over 750,000 rounds before I had my first squib load, and it was in the world championships, and I lost nine rounds because of it.  It can happen to anyone, but in my case it was from a sticking powder measure that didn't return completely to the start position due to a buildup of accumulated debris.  I took it apart and thoroughly cleaned it when I got back home, and then added an RCBS Lock Out Die to my press:

Hope this helps.

I don't see any places for error, unless your reloading room is in an out building where you can't control the humidity. So I have to side with Fred and maybe leave it at "Poop Happens".

You might look into doing these things to add some insurance...
? If you insist on using TG, then order the optional mini-powder bar Dillon developed for 25Auto. Talk to Dillon and see if this might help.
? Fit a spring or rubber band around the powder bar to make it snap-back on return. A consistent snap will work to defeat bridging and clumping.
? Lubricate the powder bar with powdered graphite.

Snap-back helper...



There have been several versions of the Dillon Powder Bars. If you'll notice, the photo shows the older black ones, which I believe is an aircraft anti-friction coating for engine parts. I'm not loading near the volume that you are, but still even with this coating I regularly squirt graphite into the hopper.

I'm giving up on Titegroup.   I'd bought a bunch from a guy who was moving.   Shifting to my last bottle of 7625.   Keeping it for nostalgia isn't worth it.   Will go slow and watch close.

1) ALWAYS look at the powder charge in the case before placing a bullet on the case.
2) If possible, ALWAYS run an RCBS Lock-Out die.
Never assume there is powder in the case, or even the right amount without at least one of the above checks.

Read this. Lots of load info...

Could be that you seated the bullet but did not get a good firm necking back down (taper crimp if you will) of the casing. Belled too wide or a accidental short stroke. When the particular round cycled it could have "popped" the bullet out of the casing and stuck it into the rifling. I have seen this happed
a few times the primer then makes the bullet stick.

I don't know for sure but that's my guess on this one.
