Some of us have bought the GINEX primers because they are available.
My experience with them in small pistol is that they a bit harder to install and the cups are harder and I get misfires in some pistols.
In rifle we have accuracy standards, and a new primer means making a small adjustment to the load (up or down). I used to buy my 308 brass pre-loaded with the Federal match primer, but I once had a call from the factory to say they could not get 40,000 Federal primers all of the same lot number - would it be ok to use Winchester? I said yes and found I had to drop the load slightly. The Win was about 40 fps faster.
I have not yet run a similar velocity test with the Ginex primers.
What I have done is fired different primers in a 3" 45ACP revolver and photographed the muzzle flash.
In these tests, the hot primers are white hot and the milder primers are orange. Hot primers are required to ignite powders with heavy deterrent coatings, such as ball powder and the slow rifle powders.
The Ginex primer does not appear to be "hot". The flash is similar to the Federal:
The standard CCI primer is noticeably hotter:
The standard Winchester is a hot primer. They say it is suitable for standard loads of ball powder. I use it for that purpose.
The CCI Magnum primer appears to be similar to the Winchester standard, and the S&B looks hot, too.
The Remington magnum primer is hot. (Of course.) I do not have any standard Rem primers to test, but memory is that they are also quite hot, like a Winchester.
I had a single pack of old CIL primers, so shot one of those, too.
In my experience, a change in rifle primers may need a small change (0.3gr) in the powder charge to get the same velocity. When I change pistol primers my only concern is a harder cup causes misfires in some of my striker fired pistols and some revolvers in double action.
The solution is the Federal primer. Federal uses a different priming compound than the others. It is more sensitive. (hence the different packaging.)
