Ginex SP primers seems tight in new 9mm cases

[rhodesengr]

I did a search in this sub-forum and it does look like others have noticed this.

I have been loading 9mm using new brass from Starline. I have CCI primers for comparison. The Ginex primers are much hard to push in compared to the CCI primers. Almost "scary hard". I have two RCBS hand primers. I have the regular one where you need to use the correct base and the universal one where they have expanding jaws. I had to stop using the universal one because I was actually popping the case out of the priming tool. Some of the Ginex primer are dented after being pushed in.

I have a primer-pocket reaming tool (Lyman brand) and I have tried reaming the new primers pockets and that doesn't seem to help much.

I am hoping that the pockets will loosed up after being shot, de-primed, and cleaned.

Just wondering if anyone else has other ideas or similar experience.

I just loaded my first few hundred 9mm with mixed head stamps using Ginex SPPs and noticed something similar. I believe it was S&B cases. When stood on end they'd wobble and the primer still stood proud. I use a RCBS bench mount primer tool and an additional go round would seat the primer properly in the pocket. Next go round I'll be more aware...

I have an occasional problem with them misfeeding in my Dillon SDB so I’m using them more in 38 special and using my CCI and Winchesters in 9mm. That said, no regrets. I got them at a reasonable (for these times) price and I could buy as many as I wanted, and they do reliably go boom. I do look forward to when I can buy what ever I want and put these on the back of the shelf.

You have to use what you can find these days. I've never used foreign primers and hope I don't have to, but from what others say, the foreign ones generally work well. I've had some older American primers that were very tight but can't recall that happening with those made in the last twenty years or so.

If I was deforming primers, I'd try them in another cartridge or different batch of brass. If that didn't work, I'd wait until I could get better primers. Deforming during the seating process sounds a bit hazardous.

I have run into the same problem with ginex small pistol primers. They seem to run a little tighter than cci, federal, remington, and winchester. I run a single stage Hornady Lock N Load and seat the primers on the down stroke (ram is down, lever is up) just after decapping. I’ve found if I go slower when seating it turns out ok with maybe one or two out of 100 which get totally deformed. I also experience slight denting on the primers. So far it has not been a problem. A local shooting range which reloads and sells for range ammo uses the primers and also says they run into the same thing with their Dillon progressive presses. Not major problem but occasional inconvenience.

I don’t have a solution yet other than running them in brass already several times fired. Primer pockets are thus a little more roomy. I’ve found in 9mm the Winchester White Box brass seems to have the tighest and smallest primer pockets. I often toss it when I run across one.

I picked up the ginex for a reasonable price back when primers were totally unavailable so I don’t complain about them too much.

In my experience CBC cases, and ANY NATO cases with a crimp are harder to prime with GINEX: however...

They have been very reliable and shot very well in all calibers I have used them in, including SPP cases for 45 acp & even 10mm. There seems to be no problem with nickel cases either.

I can only confirm that availability was not limited, the price was easily competitive and I shan't worry about running out anytime soon!

Cheers!

I have never used Ginex primers, but I have also noticed that S&B and CBC brass can be very difficult to prime with any primer brand. And primer pocket reaming may not help much. Nor does swaging the pockets. Domestic brass does not seem to have that seating problem.

As with ALL products made in mass production there are tolerances to every dimension, this includes cartridge cases and primers from all manufacturers. So, different primers fitting tighter or looser in different cases is to be expected.

This observation/question comes up very frequently, I would think most people dealing with items such as firearms and related items would realize this! The answer is to just apply enough additional pressure in the priming operation to overcome the
additional resistance!

If this is too much for you maybe you (whoever reads this)are not sufficiently detail-oriented to safely re-load ammunition in the first place.

I found a carton of X treme LPP primers made by Ginex and they seem to load fine. Most of my brass has been loaded several times with low pressure loads and that may have a bearing on that.

If reaming or swaging do not work, how about lubricating them? a litle daub with primer sealant like military ammo might help the primers slip in, then dry and seal them. Time consuming and an added hassle when decapping for sure.

Just use primers that fit.

not always possible, last time I was in the LGS I did not see winchester, federal, cci or any other primers on the shelf. if you asked they had CCI behind the counter.

I'm in agreement with you in a limited way, but earlier someone mentioned actually distorting the shape of primers because of difficulty in seating them. That's a potentially very dangerous practice. The problem may be with the operator, the primer seating tool, the primer, or an integration of the three.

If the problem can be isolated to the primer itself, waiting on the availability of a suitable primer is easily the best choice. No one needs primers so badly they risk personal injury by using ill-fitting ones.
