Half the servicos aventuras primers I have used fail

:uhoh:
I went through the Tula learning curve pre-internet.

I confirmed today that a weak hammer spring compounds any issues with these primers. But I already knew my guns with weak ignition need thin primers. The SyA are now in the same process position as Fiocchi and Tula. I am out of WSP and wonā€™t replenish them.
 
Some of us went thru this with Wolf primers back in 2012.
There were even some who swore their seating was NOT the issue, it was the primers.
All the Similar Theads at the bottom of this thread are proof of that.

I remember putting a shim on my press where the priming pin hit and adjusting the stop screw on the opposite side shorter to allow the shell plate more downward travel.
Even that was not enough and still got some primers that needed a second hit to ignite.

Later I found that the spring on the priming pin was coil binding, limiting its travel.
I cut a coil off the spring and got 100% primer ignition!
That shim is still there today and I still push on the lever with crushing force.

Looking at the SAMMI min/max primer thickness posted here reveals that seating primers 0.003" below flush is not enough in all cases.
I have waited for others to make this point, but no one has, so...
jmo,
.
I went through the Wolf primers back then. Really had to lean in to them to make sure they were bottomed out.

0.003" seating depth is only valid if you have measured the primer pockets and primer seat height and that is what you get. I really think 0.003" is the min suggested, where the range is actually 0.003"-0.005". But like pointed out if every thing is dead perfect in center spec it works, not in real world conditions. The reason I say seat to bottom and don't worry about measuring. I'm not going to measure every primer pocket and/or uniform 10k+ pieces of pistol brass.
 
Excellent! Thanks.

I suspect these are thick enough for use in SR as well. Maybe not where the possibility of a slamfire exists but anywhere you would use a WSR primer.

I will try them out in .357Mag and Max with W296 and No.11FS next.
I have had no issues with them igniting W296/H110 and today I tried them with Ramshot Enforcer same results no unburned powder, complete burn and accurate. They can handle these powders with ease which I like as I donā€™t have to buy magnum primers then for one caliber. I think you will get the same results. I just may have to try a few in 454 Casull as it uses SRP just to see how they react.

Iā€™ve already burned through 200/1000. If I designated the remaining 800 as single action and single shot magnum only it would take me (probably) a year and a few months to burn through them all. That way I donā€™t need to worry about weak springs or seating problems. I currently use small rifle for those things and I have plenty but why not save the good stuff if I can? šŸ˜‰šŸ‘

The issue with Wolf primer not igniting 100% turned out to be harder primer cups and Wolf ended up offering refunds to customers of affected lot # of primers.

It was same with Tula SP primers with particular lot # that had harder primer cups (I found out these primers were 100% reliable when used in .45 ACP cases with SP primers)

With all the discussion taken place on several threads up to now, issue with Servicios & Aventuras primers seems to be primer seating depth to set the tip of anvil against the priming compound as expressed by @9mmepiphany below with 100% reliability with 3000+ rounds:
You're likely correct given your reloading process/equipment ... At a match this weekend, I ran into a buddy who mentioned that he used these primers because of their price. He was loading them in 9mm for use in everything from his SIG 320 and 365 to his PCCs(Ruger, SIG, and Leadstar). He's up to 3000+ rounds so far of the 5k he loaded and hasn't had any failures to ignite since the first hundred. He said it was simply a matter of increasing primer seating depth on his press

I have noticed (and this may have been presented before by someone?) that the SyA's already have the anvil legs "preloaded"...

SyA - on the left ... WSP - in the center ... CCI - on the right
Well Iā€™ll be! I hadnā€™t noticed that before.
Yes, it was me who previously posted that different brand primers have different anvil height and tip shape and are shipped with differing amount of "pre-load" of anvil feet sticking below the primer cup. But anvil tip is not in full contact with priming compound for safety reasons during often harsh shipping/handling process to prevent primer ignition. So to ensure reliable primer ignition, when we seat primers, seating depth must be deep enough (Around .004" below flush) to push anvil tip against the priming compound that requires 2-step primer seating - https://www.thehighroad.org/index.p...-and-discussions.778197/page-10#post-11386382

Step 1 - The initial resistance you feel when seating primer is primer cup being pushed down the primer pocket. Depending on the primer pocket depth, seating primer cup flush may not set the anvil tip against the priming compound.​

Step 2 - The secondary resistance you feel is primer anvil feet bottoming with primer pocket and sliding up inside the cup to pre-load/set against the priming compound (.004" below flush) and face of cup deforming (.008" below flush).​

Take a look at different brand primers pulled apart and you will see different anvils with varying heights and tip shapes used.

Due to different anvil height/tip shape, you will notice shorter Tula/PMC anvil with less pointed tip will be "pre-loaded" deeper with less anvil feet sticking below the cup compared to Winchester/Magtech.

Gee, I don't recall any of that "harder primer cups and Wolf offering refunds" discussion here on THR.
It could just be I'm senile, could you post links to those 2012 Wolf primer discussions?
thanks,

Yes you posted about different primers, but I don't see anything about the SyA specifically in your findings.
As seen in my pic, you can't see any of the anvil legs(feet) on the SyA's...................................that's what I was getting at specifically with my picture..................... :)

Yes, with very little anvil feet sticking below the cup, there's less opportunity for reloaders to add any more "pre-load" to the anvil tip against the priming compound.

So you better seat these primers far below flush (.004"-.005"+) as seating them just to flush may not ignite them as anvil tip may not be set against the priming compound when the firing pin/striker indent the cup.

Don't be afraid to seat primers hard - https://www.thehighroad.org/index.p...-and-discussions.778197/page-10#post-11386382

BTW, properly seated primers should look like these. Notice some flattening of primer cup face at .004" below flush and additional flattening of primer cup face at .008" below flush (You can see variation in primer cup hardness by amount of primer cup flattening). My QC check is to load finished rounds in bullet tray and run my finger tip over the primers to feel below flush seated primers. Any high primer I detect gets seated deeper​

I am still one to believe that you seat them to the bottom of the pocket, as that sets the ā€œdepthā€ā€¦.
I also donā€™t see any need to seat them sooooo hard that they get flattenedā€¦.
But, whatever works me doesnā€™t have to work for othersā€¦
Hope everyoneā€™s primers go bang when they supposed toā€¦..

I like to see a full circle impression of the seating stems face. But I donā€™t like to flatten the whole primer.

But if primer won't ignite because anvil tip is not pre-loaded against the priming compound/cup, then you have no choice but to flatten primer cup. ;)


I can tell, you are strongly resisting the possibility the primers are not seated deeply enough.
Sometimes, it is what it is.

Walkalong's linked post reaffirms why primers must be seated deep enough to pre-load the anvil tip against the priming compound or the firing pin/striker indent won't ignite the primer - https://www.thehighroad.org/index.p...primers-before-shooting.832434/#post-10757047

"Primers need to be seated until the anvil legs touch the bottom of the primer pocket (Minimum), and then a little more so the cup pushes down around the legs, up until it hits the bottom of the primer pocket (Maximum).​
If seated to little (Anvil legs not touching the bottom of the primer pocket), the firing pin has to seat it fully and then have enough energy left over to crush the priming compound between the cup and the anvil. Sometimes it does not, these are the ones that so often fire on the second try. The first try seats them fully, the second try fires them.​
[Live life] has some great primer pics here somewhere that shows the cup and anvil and how they are positioned with each other prior to seating [See post #155]. The anvil legs are sticking out of the cup just a little bit.​
After fully seating the anvil's legs and the primer cup is hard against the bottom of the pocket, it takes a great deal of pressure at this point to damage the primer so much it fails.​
It is fairly easy to seat a primer too soft, not fully seating it, so that it misfires, but difficult to seat them so hard it damages them to the point of not firing. This statement is based on my decades of seating primers with various tools. I have never had one fail from being seated to hard/deep. Not saying that with some primer tools and some gorilla grips it can't be done, but it is 100/1000 times less likely to happen than seating one too shallow/soft.​
We have threads here all the time when failures to fire end up being primers seated too softly/shallow. I can't remember one where it turned out someone managed to crush a primer into submission. I would suggest to all to try it. Some priming systems simply cannot do it for mechanical reasons. Some might have enough travel to do it if you have the strength, That cup surrounded by the brass primer pocket is tough to crush. Very tough."​

Personally, I have ONLY primed on a Dillon 550 whether it be progressively or 1 at a time single stage style when loading rifle stuff.
Have only set the primer to the bottom of the pocket fully-----never having to "flatten" a primer.

You even quoted @Walkalong :
...and nowhere does his statement say to "flatten" any primer, just seat it fully so the cup "swallows" the anvil legs.......

"Primers need to be seated until the anvil legs touch the bottom of the primer pocket (Minimum), and then a little more so the cup pushes down around the legs, up until it hits the bottom of the primer pocket (Maximum).


I think there is waaaaaaay to much thinking here.............................


THIS IS ONLY MY OPINION...............................squish 'em like a pancake it that's what works for you.......................... šŸ˜

This is what I do also.

I have found folks who can't distinguish "flush." I tell them to run their fingernail over the primers and if it doesn't catch on the step up of each primer pocket, it isn't deep enough
 
Like Mr Flintstone,I had a few fail to pop when I first used them. Now I turn 180 in the shell holder and press again when priming on my LCT..So far,all good.
I use a handprimer and also do the 180 rotation. Never a problem. Sometimes primers just don't go in straight. That's all primers. I have no experience with the primers in question. If they are a bit larger they probably aren't going in straight and only one side of the anvil is against the bottom of the primer pocket.

But I prefaced the post with "if primer won't ignite"
But if primer won't ignite because anvil tip is not pre-loaded against the priming compound/cup, then you have no choice but to flatten primer cup. ;)

While those of us who have reloaded with "standard" sized domestic brand primers which have worked well the way we have primed over the decades, reality for many in 2024 who can only source slightly larger sized "Metric" primers is they now may need to seat primers much deeper until they experience 100% reliable ignition as @9mmepiphany posted - https://www.thehighroad.org/index.p...-i-have-used-fail.926588/page-6#post-12854918

At a match this weekend, I ran into a buddy who mentioned that he used these primers because of their price. He was loading them in 9mm for use in everything from his SIG 320 and 365 to his PCCs(Ruger, SIG, and Leadstar). He's up to 3000+ rounds so far of the 5k he loaded and hasn't had any failures to ignite since the first hundred. He said it was simply a matter of increasing primer seating depth on his press

Works for me.

The revolver I know to have a weak mainspring and the one with a short stroke gave better than expected results. Judging whether or not a primer has ā€œhit bottomā€ by looking for a ā€œcrush ringā€ has worked for me for quite a while.

That is all I was reporting.
Nothing more.

Keep in mind Iā€™m not trying to tell anyone else what to do or how to do it. I avoid doing that.
