Ginex LR primers - weekend experience in 45-70
- Thread starter wasa
- Start date
We have run into some poor ignition of CFE Pistol and Titegroup, using near max charges, .357 and .38 Spl in cold weather when we used Ginex primers.
I had a discussion on here with some others who had similar experiences: Squibs and a LOT of unburned powder in the action of SAAs and lever actions.
We'll use the Ginex primers, but save them for warm weather.
FYI:
We only dry tumble then deprime/resize.
We recently used the same brass, powders and charges, in even colder weather, but with CCI Primers and had no problems.

've found Ginex SP unreliable in 357 mag with CFE pistol powder
CFE in a 357 is really a low power load anyway. I use it because I have lots of it and I'm not trying to get max power anyway. But even then I think the CFE powder charge is a little too much for a ginex primer.
Ultimately my experience with ginex primers are this:
SP- reliable in 9mm, especially hammer guns and PCC. Questionable in 45 ACP. Not recommended in 357 or above. Striker fired is questionable
SR- reliable in .223 for bolt action or semi using somewhat fast powder for bullets in the 55 gr range
LP- Reliable in 45 ACP including striker fired like Glock 21
LR- Reliable in 308 size cartridges. Would use them to hunt etc in cases of this size. I've used them in 300 PRC but mostly as fun "range" loads. Had a couple of failures to ignite in the last 500 rounds of 300 PRC so I would not use them in magnum cartridges when reliability is truly important.
From Ganderites tests it seems like the Ginex primers don't flash hard. I think they are great primers when used appropriately.

I'll amend that by saying I changed out the striker springs in my Glock 21's and Ginex SP seem fine in the 45 ACP now. But I replaced the (old and worn) factory springs which I think are 5 lbs with Wolf springs which are 6 lbs.
I've used them in 9mm and .38 spl, with several powders (Titegroup, WST, WSF, Unique, Clays, and Bullseye), in several guns. I haven't encountered any issues, however, I don't shoot in anything below 0 and I keep almost everything I own stock. The only gun that won't set them off is my worked S&W 66 (Federal only). I don't know about the LR but the SPP are as good as anything at the same price point and availability.
I've been wondering about those Ginex primers for a while...thanks to all you NUTZ who always take the time to post up stuff like this (and previous findings @ Gatehouse)) makes it much easier goin forward for the rest of us enquiring minds ! KUDOS gang !
OK, for anyone still following... all loads were from Speer 15 (hardcover, although I believe the free online version is the same).
43gr IMR4198 (Speer max for lever 45-70)
47gr Reloader 7 (Speer max for lever 45-70)
55gr A2015 (Speer max for lever 45-70)
all of these, in a heated 5 sided building, with Campro 300gr bullets, Starline cases, and Ginex LR primers, had ignition issues, and one load with the 43gr of IMR4198 resulted in the picture I provided in Post 1.
So, although other sources may have different powder levels (like Hodgdon has 57.2gr max for IMR4198) I used the maximum published load in my Speer manual for my Henry lever 45-70.

My notes say Speer, Nosler, Lyman, and Hodgdon all have "lever" 45-70 loads. I think the SAMMI specs are trap-door loads, and there is no official max pressure for lever or "Ruger & T/C" loads.
My goal would be bear hunting at up to 100 yards near Sudbury ON. Don't think I'd have a 200 yard shot. I want to consistently hit a paper plate at 100 yards with enough energy to ethically harvest a bear with Hornady XTP 300gr bullets. My goal with the three powders was to see which was more accurate.
