I'm sure he doez-Just don't want to assume. BTDT.

The fact this issue only happens in the HG's is curious.

Truly, that is a squib-TY. ;)

Was this a new lot, or can of powder?

Thinking you will need to 'up' the charge a bit.

Could/would you PM me the exact load info?

I was right behind you at Gibsonburg when the "pfitt's" happened and with you at the unloading table. I was surprised the force it took to push the bullets out.

I was just there today and ran 30 rounds thru my new Uberti, came home and decided to measure the gap between the cyl and barrel, 4 thou. Measured the other Uberti I have and same thing, 4 thou.

I am just learning from all of this. I can't remember which stage you were at and if you had fired the pistols/rounds before. Here are some things I thought of.  I am pretty sure you have probably covered these bases, but what about soft lead bullets that leaded up the barrel more than usual.

Sure hope you get a sure cause of this.

I did learn that there is a tool I need to make for my own and hope I never have to use it.

Good Luck CC, WW

If you do not load below the minimum powder charge weights. You'll be fine.

I'll bet if CC ups his charge weight .03-.04gn and uses a roll crimp. His 'pfitts' will be a thing of the past.

I use a strong roll crimp,,, I've loaded at least 4 lbs of red dot with my recipe so far, most likely 12lbs so far,, been using red dot when I cudn't get clays anymore ,, never had an issue..  I will do some testing tomorrow or sunday to see what's up

PLZ post up your findings.

All loaded with the same brand/lot of primers??

The bullets you use-If a wax type lube. Are you SURE there's no lube left on the base of the bullet???

all were winnies out of the same lot,,,  bullets had no lube,,  they were ones I had torn down before,, because of squibs years ago,, I knew the problem then,,  my thot is that maybe those bullets had residue on them that caused the contamination..

Since this happened before and knowing the load you PM'd me. I will stand by my statement to 'up' the charge .03-.04gn.

the before had nothing to do with this,,, I had tried a cleaner in my media that contaminated the powder,   the only link is these were the bullets that I had pulled,,,    the powder contamination before turned the powder, clays at the time, from flakes to granules in about 10% of the cartridges..

Did you leave your powder in the hopper? Powder makers say that when you are finished you should put the powder back in the can. powder is affected by  moisture in the air and dry air. V.D.

If you are using that posted 148 grain load-and still squib'n. I would up it .02-.03gn. to compensate for the lighter bullet.

Howdy CC, I know several other shooters that use the same. IMHO it ain't the powder. Good Luck:)

Till proven otherwise-I'll say the load was to 'lite'.

The B/C gap let the psi escape.

Where did the bullet lodge in the HG?

Maybe warmed up the wrong thing. When you do some test firing stick the gun in the freezer. Get it down to that 19 degrees.

Re; thermal expansion, thermal contraction. Bullet expanded, barrel contracted. You know how hard it is to start a car engine in cold weather...  

Just an idea. Just trying to help.

I wouldn't be chiming in if I hadn't been RIGHT there when it happened.

Whew, definitely something on the old bullets.   They weren't lubed with Gorilla Glue, were they?

 

Nobody has hang fires anymore!  Didn't I say that last week?   Wow, now I gotta make a retraction.     :o:ph34r::blush:

 

Good luck, and toss them old bullets out!   They're makin a liar outta me!   GJ
