Winchester WSP Small Pistol Primers

Anyone have any problems with these?

I bought a 100 pack of primers to test them with some loads I worked up for my .40S&W and didn't have any problems. After I approved their performance, I bought the 1000 pack so I could use them in both the .40 and my wife's 9mm.

Today, while doing some test load firing, my .40 had 2 failure to fires. After carefully clearing the gun, and reloading the rounds into the magazine; they fired fine.

I don't load my own self-defense rounds, but it is kind of an irritant while shooting.

Any ideas on something I could have done wrong, or is this normal?

Sounds like some primers were not fully seated. First strike pushed them further into case, while second strike caused ignition; however, the firing pin strike can be dissipated if there is to much "gunk" in the firearm.

Any time a primer fires on the second strike, I have always found it to be a seating issue. As mentioned, could be carbon build up, primer just not fully seated, etc.

Did you notice the depth of the pin indentation after the first strike? What primers were you using prior to switching to the Winchesters?

They were all from new, never fired, Winchester brass.

Winchester WSP primers are all I've used... I started reloading the beginning of the month.

The primer was barely dinged the first attempt to fire. 2nd time they were (I'm going to coin a phrase here lol) well-dinged.

I doubt that it is the weapon. It was about the 15th round from a totally clean firearm. I don't know if you've ever stood a USMC weapons inspection, but I've stood many. Many gunsmiths cringe over how anal I am at cleaning my weapons. It's just 2nd nature to me after almost 10 years active duty.

I did notice that it didn't take long for the residue to start building in the barrel. After the ftf, I tore down the weapon to inspect. I'm using Power Pistol powder... is this a notoriously dirty powder?

The loads I was firing prior to the ftf...

10 rds of: Hornady 155gr XTP HP bullets, 7.6gr of Power Pistol, New Winchester Brass, Winchester WSP SP Primer

Approx 5 rds of: Winchester 180gr FP-FMJ bullets, 5.6gr of Power Pistol, New Winchester Brass, Winchester WSP SP Primer

Then, ftf... another 3 or 4 rounds... and another ftf...

Previous posters are right, people think if it didn't fire the primer was seated too deep but in fact it is just the opposite.
Two easy ways to check, just set the round on a flat surface. If the primer is too high the shell will rock a little, also
hold two shells base to base and there should be no wobble if properly seated.
There are a few makes of brass that do not have a flat base but most do.

Yeah, I think I'm going to chalk this one up to not seated properly. Rookie mistake I guess. I'd rather do that than overcharge! Thanks for the input guys... I appreciate it

Add my name to the list. Very likely they aren't fully seated.
Some worry about carefully seating them to a certain clearance below the case head. Seat them as far as they will go firmly and they'll fire 100%.

With regards to Winchester primers I have had 1 dud out of 19,000 + rounds.
