Ginex SP primers very tight in new 9mm brass

[tigerpan]

Did you clean the primer pocket? It may make difference

[stormvet]

I can attest to this, recently loaded 5000 of them in 9mm and 40 in mix cases. More difficult to seat then any primer I’ve ever used, with some I had to use more pressure then I was comfortable with. I’ve never had a batch with so many high primer rounds.

The next batch of 5000 I reloaded were with Remington primers, smooth as glass no issues. I’ve used CCI, Winchester, Federal, Remington, S&B, etc amounting to over 100,000 small pistol primers in my life and have never had the tight fit issues like I did with the Ginex, I will avoid them from now on.

If you are asking me, I tried reaming every case with a pocket tool in a drill motor. That did not seem to help. That was in new cases.

I recently bought a Dillion SDB. I have used it once with CCI primers in new (unreamed) brass. Those went in fine. My plan is to try the Ginex primers again in my SQB but only in used, cleaned and reamed brass. I have not done that yet.

I think it is obvious from all the responses here that the Ginex primers are larger. I just hope my SDB does OK with them.

I guess too be fair it could have been that lot # that we used and may not be the norm for Ginex. But it absolutely has made me shy away from them, but in these days of high cost and low supple I better not say never again.

You're just having a confluence of metric primers and tight Starline primer pockets (their norm). Then you're comparing the experience to seating CCI primers, which I've always found slightly smaller based on how easily they feed through vibratory primer tube loaders.

Just curious, are the Genix primers that you're loading the nickel plated ones or the brass?

I've only loaded about 600 and haven't run into any issues...but I'm priming on a Lee Automatic Case Priming (ACP) press. All my primers are seating below flush and igniting reliably

brass color. I have not had any firing problems. Just concerns me if the force required to press in also dents the surface.

Hopefully, my SDB with fired and cleaned brass will let them in a little easier

brass color. I have not had any firing problems.

I suspected as much. The brass primer cups seem to be harder...which would make them harder to seat.

The nickeled primers are almost as easy to ignite as Federal SPP in my revolvers...you just have to insure that they are seated below flush. I've been using them in place of my CCI in 9mm .38Spl, and SPP .45ACP

I know this thread is 4 month old but I'd thought I would add some info. These primers do seem to put up some seating resistance in the primer pocket. I found that the brass case makes some difference. FC, Win, CBC, and others seem to give resistance. RP and Blazer seem to accept Ginex primers easier. Speer did accept with slight resistance. I did swage some CBC(even though they are not crimped) and Speer, along with military crimped brass. After swaging, the brass did seem to accept the Ginex primers with more ease. I may try and swage some FC and Win brass to see if these would work. Seems like more work than it should be but times are tough getting primers at a reasonable cost. If only Federal and CCI primers were easy to get and at a decent price. Hope this helps.

Beggars can't be choosey. I bought a 5000 sleeve of Ginex because they were available. In spite of the fact that I previously used a primer pocket uniformer and crimp remover on all of my Starline .38 brass, the Ginex would not seat using my Rockchucker. I think Starline has a little thicker wall than other brass based on the resistance when resizing and expanding. Federal and CCI primers go in like butter. Winchester primers are a little harder to seat, but they will seat.

I had the same problem with 9mm brass (Blazer and FC) and Ginex primers. So I ran some W-W and Blazer 9mm brass and Federal .38 brass through the same uniformer and crimp remover. I chucked the bits in an electric screwdriver and put a decent amount of pressure on the brass to make sure that the uniformer and crimp remover bits went fully into the primer pocket.

This allowed the Ginex primers to seat, although it took a lot of pressure and sometimes pushing them in twice. I also run my finger over the primer to check each one. This is a painstakingly slow process, but since I can't find any other SPPs and am saving the last few thousand of my Federal SPP for special occasions, I am making due.

As a final note, I compared the spent Ginex primers with Federal, CCI and Winchester. The firing pin mark is much more shallow with Ginex (same load and same handguns). I suspect it would be more of a pain if I was reloading on a progressive press. As I said, beggars can't be choosey.

Yes this is correct I think they are a Like .0005 larger in size to. Is this who I think it is? Bruce

[dmy]

Yes Bruce. You've heard my whining about Ginex SPPs personally.

Yes Bruce. You've heard my whining about Ginex SPPs personally.

LOL

I reloaded more than 2K rounds with Ginex SPP on Lee Progressive press for: 38SPL, 40SW, 45ACP (SPP brass) everything reload and shoot OK. Never reload 9mm so I don't know.

My new favorite SPP’s are Fioochi, been finding good deals on them and loading the crap out of them about 13000 so far. Smooth and easy seating, always go boom very happy with them.
