The Ginex or the White River?

Yes, they're superb. No issues what so ever. I've used them in 9mm, 38 special and 357 magnum loads. The load in the press well and strike well. I have all makes of primers so I have tested alongside others. Worst I've found, absolutely do not buy, are Russian murom primers - unless you have a strong hammer. They're soft and mushy and crush when loading and I've had more misfires than a 90s Ducati on a wet day.

Mmm that's interesting. I've shot a lot of Murom primers. Small Pistol for 9mm, small rifle in 223, 22 Hornet and, yes, 9mm. Large rifle in 308, 7x57mm, 243, 6.5x55 Swede. No issues at all. Ive bought up old stock and recent. Can't say that I'm afraid about some Winchester SRP that gave me bolt face burn on my 223 and 22 Hornet. Used those up in my 9mm also.

A mate recently bought some Ginex small rifle primers for his .223, he was loading them into ADI brass and found them a bit tight to seat.

The primers are quite soft as the firing pin on his Ruger American was penetrating them and when he was depriving/resizing the brass there was an average of 1 out of 6 cases which he couldn’t get the primer out due to the primer already being pierced.

He switched to small rifle White River primers and found no issues what so ever in his .223

There’s a few comments of the internet with people commenting that the Ginex primers are soft and primer penetration is a common issue, based on our experiences I would recommend choosing another primer.

He’s also been using large rifle White River primers in his .308 with nil issues

Have used these Ginex SR primers in FC & ODL cases/Varget/73 ELDM’s. They went alright with lighter powder weights up to 24.3 gr but at 24.6 gr got pierced primer’s, 5 out of 10 trial rounds. Only using Ginex for lighter/reduced loads now. Gone back to CCI and trying White River. Have got a useful 600 metre load so happy for now.
