Ginex SPP Initial Impression

I have found that most European made primers are slightly larger than American made primers. This is especially true with some 209 shot shell primers. I know once you start using Cheddite 209 primers you have to stick with them since they are 0.002" bigger than American made 20 primers.

With mixed brass in military cartridges such as 9mm and 5.56, you have to watch for crimped primer pockets and remove the crimp.

Since spraying them w/Oneshot only takes 10 seconds, if these all go bang, they will likely be towards the top of my buy list.

Good to know. An alternative would be to spray the case instead if you’re worried about possible primer contamination from spraying. One shot says it’s safe and I’ve not seen any problems with it yet, but I’ve never sprayed primers. Also, you may not see a contamination problem immediately, if there even is one. Thanks for the posting. Good luck.

Peep thanks for the info. Personally I am glad I passed on these as PV had some the other day. I don't have time to to lube primers and turn cases to make things work. In all my years of reloading I have never had issues with CCI, Win or Federal primers. Crimped primers in Mil spec ammo is another thing but that's a whole different ball game and easy to deal with...

It seems I remember Lee has stated that their case lube won't foul the powder. I'm thinking in moderation, it hasn't harmed the primers.

After reading up on One Shot, it looks intriguing enough that I want to purchase some. To see for myself.

Have you tried lubing the cases with the homemade liquid lanolin/red ISO HEET mixture and see if that helps? Seems it would be easier that way and just a quick tumble after loading to remove the lube would be a lot less work.

Ahhh okay. I may have to switch headstamps, I have all the big brands. I get range brass every week, so I like to use that if possible. Any idea if any of the following are the most forgiving?

-Geco
-Win.
- R.P
- Fed.
- Blazer

I am an equal opportunity reloader. I use them all (in all calibers)other than Geco as I don't have any

Never heard of lubing a primer pocket?? I do spritz my clean brass with case lube but they still have the old primers in them. I do not mess with "cleaning" primer pockets.

I say it's your brass not the primers but, there again I am not there.

It very well could be a combination of both. Some brass have tighter primer pockets and/or crimps that need removed. And European primers are larger than US primers. Now the size difference that I have noticed is anywhere from 0.0005" to 0.0025". Now 1/2 a thousands of an inch should not cause any issues but 2 thousands of an inch definitely will.

I started using Oneshot on 9mm about 1.5 months ago. Hornady says it won't foul powder, so to test that, I have sprayed it directly into about 90% of the 1600 rounds I have loaded and shot. I haven't had any issues.

Thanks for that info.

May I ask where you bought them? Still awaiting my TriFusion Tactical order…

Powder Valley last week. I also have some on backorder with Northfork.

How much were they from PV, if I may ask? The Ginex's from North Fork are priced at 6 cents apiece including shipping, if they ever show up.

Since you pick up so much range brass have you considered one of those Franklin Arsenal Case Prep Centers?

Yeah, I am really trying to avoid being a Fanboy, but I like the idea of structurally tough primers in my ammo. Maybe they could be less susceptible to pressure risks? Not sure, but I assume the toughness could only be a good thing.

Do +P or +P+ ammo manufacturers use "extra tough" primers?

Thanks for the update.

I had the same experience. I happened upon a brick last January. I'd say 90% were tight to seat, most to the point of dimpling the primer. I had three that were so tight I didn't fully seat them and wasn't comfortable taking them out either. I tossed those in the fire pit.

On the bright side I had zero FTF, but I definitely won't buy them again. I did measure them and they were slightly larger. I think it was +0.0002

Sounds similar to my experience with Fiocchi SP primers that were metric sized slightly larger and took greater effort to seat them and for some once-fired tighter primer pocket cases, even seating them to flush was no-go (I usually seat primers to .004" below flush).

I did like how consistent they were in ignition and produced good average size groups for me. I reserved remaining Fiocchi primers for well used brass with slightly enlarged primer pockets to extend the life of brass.

These are not B list primers.

I am well stocked for primers but will keep both Fiocchi and Ginex primers in mind for future shortages when I can't find my preferred brand primers.
