There are 2 different versions of the SR primer that you find. One is the Primer 4,5/3-P3 for Small rifle. The other is designated as a 5.56 primer. The Small Rifle primer measures the same as a Fed 205 and seats fairly easily. I have not used any of the 5.56 primers so I can't comment on them.Can someone that uses Ginex SR primers measure the diameter of a few for compare them to the measured diameters of other commonly-used SRPs such as Fed/CCI/Rem?
As noted above by @markm87, I can imagine the Ginex primers might be of use in .223 Rem F-TR loads to get an extra firing or two out of the primer pockets, which don't always have such great longevity when shooting heavies in F-TR.
It is kind of like trying to use a 10 mm socket to remove a 3/8" bolt. The 10 mm is portion of a mm too big.They are hard to seat. I read on another forum that they were hard to seat because they were a metric primer. Still haven't figured out the metric primer part of the story yet.
I have noticed that they seat nice and tight in most cases but nothing objectionable. I've only used the large rifle primers.l've been doing a bit of info gathering and ONE gent commented abt hard seating.
Before l snag 5k of those, l would like some feedback re seating. My intended use is .223, swaged.
TIA guys n gals.
