... Hornady LNL progressive, mixed 357 brass with pockets swaged, S&B brass diligently culled, nearly an hour to do a hunderd count!
If beggars could be choosers I'd throw them in the woodstove.
No I wouldn't give them to you, I can be a real miserable prick at times but I wouldn't subject a fellow human being to the pain of ginex primers lack of consistent diameter.

Have you tried swaging or reaming the primer pocket hole in the brass? I used to do that for my 223 reloads because some of them had crimped primer pockets.
 
I'm at about 10% that I need to stick back in a seat deeper on my Square Deal. They have no feel going in. I bought 5000 from TNA knowing full well that they are like that, but they'll all go to practice ammo.
 
I also had issues seating them in some brass. S&B seemed the worse. Fed, Win and Speer all worked fine with the 750 but does take a better push on the down stroke compared to others. I actually stand when running those. Went through 5000. They all worked shot fine. Lost a few on the press at first but rare now. Picked a few thousand more at the local can tire 80.00/1000 is a good price these days. If I was you a would try running them standing up and get a rhythm of really putting your weight in that seating. Made the difference for me.
 
Over on Pistol Forum Slavex was commenting that he had to up the powder charge on these Ginex primers as his loads weren’t reaching the same velocities (and power factor for competition) as domestic primers like CCI or Federal

Has anyone else chronoed these versus regular domestic primers?

I’m used to primers being essentially interchangeable

What powder was he using? I’ve chronoed them with Titegroup (my IPSC load is 3.3 grains of TG with a 147 grain Campro, Fed small pistol) and it wasn’t so much that the velocity was consistently low, it was that it was inconsistent. The standard deviation was basically double the Federals over a string of 10 rounds. So if they picked the unlucky 3 that were low at chrony at an IPSC match then you’d be subminor if you didn’t have enough of a buffer (I aim for 130 PF).

Thanks for the info. That would make sense as I haven’t heard of primers making that much of a difference in velocity before. Extreme spread for sure.

He was using titegroup and 147gr Campro
It required .3gr more according to him to make power factor.

I’m going to have to chrony my standard 124gr Campro titegroup load to confirm it’s still close to the same speeds before I load a few thousand of them this winter.
Hopefully it warms up some day as we’re already in a Northern Manitoba winter.

Do you have a link to that thread? 0.3 grains of Titegroup is a lot, the Campro load data says min is 3.0 and max is 3.4. So unless he was trying to push 125 PF and was closer to the min load that might be pushing it on the other end of things.
 
So I picked up a 1000 of these ginex / campro primers to try out, and I just loaded a 100 in 9mm once fired mixed brass, and I would say at least %20 gave me a problem trying to seat them properly on my Dillon 550. Some of them seated nice and smooth and others it felt like I had to throw my whole weight behind it to get them to seat. One of the primers even got completely jammed about half way in and then wouldn't budge after that. I still have to go out and actually see if they will go bang or not, but I'm not feeling too confident about it right now.

Overall, I think I'll stick these at the bottom of my supply pile and maybe use them in an emergency.
