SP Primers

[viceunit]

Got an email from Norma, Argentine SPP on sale $49.99/1000 and free shipping on orders over $150.00 I bought some of these a while ago but haven't used them yet.

I'm a bit hesitant to use Argentine components since I have no experience with them. I was tempted to buy some during the primer shortage, but held out until Federal and Winchester became available. The price is certainly right.

Delivered price for 4000 came in at just over 5 cents each. I will.use them for 9 mm and other range of ammo

Thanks for posting!

I didn’t need any but at this price you can’t pass them up so I ordered 3000 and got the free shipping.

I have some I got for about that price with the free hazmat from Powder Valley. I had issues.

The first box I loaded up had 40% failed to fire in my Model 66. Some online research told me they probably weren't fully seated. This proved to be true. I've never had trouble seating primers until I bought these.

I decided to try firing the failures with my Blackhawk, which usually will set off anything because it has a huge heavy hammer that travels in a long arc before it strikes. Plus my Blackhawk has a tight headspace. All the misfires went off in the Blackhawk.

They are difficult to seat. You feel resistance and then a release. This fools you into thinking they're in. They aren't. The final resistance is significant and difficult to feel, but you have to press on hard after that release.

A lot of this depends on how you prime, and whether your priming equipment has a "stop" and how much leverage it has.

I had difficulty with the swinging Lee priming system on my single stage getting them right. I have yet to try them on my Dillion. I started priming them with a Lee Ram Prime which is not exactly fast, but priming on the downstroke with the full force of my Classic Cast is going to seat anything.

Primed that way they worked fine. The Model 66 fired them 100%, as did the only striker-fired gun I have which is a Taurus PT638 in .380.

So if you have problems don't give up. They'll work. If you get them seated right.

I got some and just threw 850 of them in the trash. With a 20% failure to fire rate I am out. Norma and Servicios are not going to get any future business from me.

I’ll try them on my Dillon press first and if there’s a problem I’m sure the Rock Chucker will seat. I don’t plan on using them for defensive use so I’m not really concerned.

Thanks though for the heads up.

I have now loaded about 600(38 Spec) I use a RCBS Bench mounted Priming tool. With my max load of Unique and a 158 gr HP Remington bullet...perfectly reliable with the 35 or so I have shot...Loaded on a Redding T-7. Going to try the Dillon 750 in a week or so

I got a few thousand of the Argentine SPP as part of a lot of stuff a few months back. I think I've burned close to 2K by now without any verifiable failures. I say that because my mdl-14 has it's spring force *very* low, so it's been one of those guns that you have to use Federals with, so I can't fault the primers in that case. No issues with the other guns I've used.
They feed great in my Dillon 650, unlike Fiocchi LRP or the elderly CCI LRP that give problems.

The only primers I’ve had fail to fire the first time have been LPP that I didn’t get fully seated. With LPP I run my finger over the primer of each round to make sure I get them fully seated. For some reason I have more difficulty seating LPP. Still it’s rare that I have a high primer.

Since I use the old Lee round tray primer I get a very good feel of the various brands. I think most users would agree Ginex are the hardest to seat, hands down the winner. The Argentine brand is second but that's not bad. They are a lot better than the Ginex. Properly seated I've had no problem with either of them going bang. I put around 8 thou of Ginex on the back shelf for extreme future shortages. The Argentine work fine in my Dillon SDB making 9mm. My other brands (Win, CCI, Rem, Fed) I use in my Lee hand primer because we all know the handle will break under too much pressure. That's why I always try to keep an extra Lee tool on hand when I find one on eBay at a reasonable price.

I've never used foreign primers, but if posts in this thread and similar threads on this forum are valid, about fifty percent of users of foreign primers mention something like an overly tight or difficult fit, or other problems. I've had very good results spending more and getting American-made primers, just as I've done for about sixty years.

If you're without primers and no US primers are available, foreign may be all that's out there. Otherwise, it might be worth the time and money to get the best you can.

I've used Wolf primers in the past and bought a few thousand of these Servicios Aventuras small pistol primers. I used a Dillon 550 to load 9mm with these. When using the same pressure to seat the primers that I use for Winchester primers, I get a lot of misfires. These SA primers take a lot more pressure to seat. I'll probably get fingers pointed at me, but the only solution I get for misfires with these is to use my hand primer to seat them again once they have been seated in my Dillon.

I've broken a couple. My current Ergo Prime is still holding up. But that's why I have a Ram Prime. It's a cheap back-up. They don't break.
