Having Failure to Extract issues with a Sig P250, want to see if anyone has any input.

Load1 (Straight from the Hornady manual)
Hornady 115 Gr XTP 5.0 Gr W231 @ 1.050
Failure rate approx 1 in 20

Load 2 115 Gr plated 4.6 Gr W231 @ 1.110
Failure rate approx 1 in 4

Load 3 115 Gr LRN 4.6 Gr w231 @ 1.110
No failures, functions 100%

What am I doing wrong here

Thanks,
JIM

Fail to extract, or fail to cycle the slide and load the next round??

1. Hornady #6 manual says 4.7 MAX seated 1.075".
Lyman #49 manual says 4.9 MAX seated 1.090".

2. You got me? Bullet shape?
It might be a tad too healthy with a Truncated Cone plated bullet which will take up more case room then your LRN load.

3. Works, What can I say!

Fail to extract. The new round is pushed up against the old, fired case

RCMODEL.

So, data discepencies aside, you think they are just too hot?
I chronoed the LRN and XTP's at 1115-1120 FPS. Didnt check the plated yet

Failure to extract can be extractor issues.

But whenever I have a gun choking on reloaded ammo, I run some factory ammo thru it. If problem disappears, then it's the ammo. If not, then it's the gun.

Actually, when I first bought it ( used ), We shot several various brands of factory ammo through it, and had issues with some of it also, the 115 LRN reloads are the only thing that function 100% in it

Is the brass you are using all the same headstamp?
If mixed brass, are the ones failing to extract a different brand then the others?

Any chance the extractor is binding up in the slide and not getting a good hook on the case rim?
Also check the hook for a chipped edge or other damage.

The 9mm is a tapered case, and should extract if it moves so much as a few thousandths to get it started out.

Well, the first problem is see is that you have a SIG P250... :)


Just kidding.

Check the brass you are using. Is it range brass or new brass? Check for non square cut extractor grooves on the bras... Winchester, I'm looking at you... Also, check the rims for nicks and burrs.

If it was the load, you would probably be seeing more failures than 1 in 20. I suspect it's either your brass or your extractor.

Do you think 4.6 Gr W231 is too hot for this bullet

"Well, the first problem is see is that you have a SIG P250"

You may be right, it is starting to remind me of a S&W Sigma 40 i once had...which I traded for a XD 40.
The XD has fired thousands of rounds without a single failure
I bought the Sig for my wife, she is ready to get rid of it, horrible trigger, and unreliable

I'd bet that the Sig works just fine with factory ammo.

"I'd bet that the Sig works just fine with factory ammo. "

Negative. When I first bought it, it choked on several different factory loads.
Only thing it has reliable run is my 115 Gr LRN reloads.

In that case, you should have returned it to SIG or was it bought used?

OK then, contact SIG, have (your serial # handy) and they'll send you a call tag.
They will service the pistol and return it to you for a total price of $110 which includes shipping both ways.

(603) 772-2302 (press #3 for Customer Service)


Or you could attempt to repair it yourself...an extractor cost $40 plus shipping.

Then you can only shoot that round thru the gun.....or fix the problem.

It's likely extractor related (hook, tension) or a magazine or mag catch issue. (top round high enough that the extracted case hits the case mouth, dislodging the spent case)

Anybody have trouble priming 9mm cases marked WCC 94. They look like they have a sleave around the primer pocket and every one of the primers go in cocked with an RCBS hand primer.

"Anybody have trouble priming 9mm cases marked WCC 94. They look like they have a sleave around the primer pocket and every one of the primers go in cocked with an RCBS hand primer."

Yes. I have had to throw a bunch of that out, different headstamps

WWC 94 is GI or NATO brass and will have crimped-in primers.

You have to ream or swage the crimps out before you can reload it as with any other GI brass.

I'd stop trying to prime it with the crimp intact.

You might have a primer go off and shoot your eye out.

I have one 9mm that dislikes 115 gr bullets of any kind.
No rhyme or reason.

Same gun will shoot 124 gr FMJs, HPs, LSWCs all day with nary a hiccup.

Does it make sense?
Not to me, but as Walter Cronkite used to say "And that's the way it is".

(ya, I know, I'm dating myself)

since you bought it used, you may want to give it a good scrubbing before you send it in for service. just a thought.

Pull the extractor and carefully check it.
Polish the back side and friction points if it's not chipped.
If it's damaged, get a new one + the spring.
I don't know how many rds are through it, but a new spring might be a good idea either way.
