They are often several dollars per thousand cheaper. At this past weekend's gun show in town, Winchester (bronze/brass cup) was $21.95 and TulAmmo (bronze/brass cup) was $16.95.Unless they're a lot cheaper than CCI, Win, etc why bother?
As far as how they shoot, they "feel" the same to me producing comparable shot groups. As to how they look, they have the same color priming compound but TulAmmo primer cup is more rounded than Wolf with slightly brighter brass finish.As for the OP's question I hope they are the same as the Wolfies.
On Glocks I have worked on with over 5000-10000+ rounds experiencing lighter primer strike, the problem turned out to be hard caked on fouling buildup at the bottom of the striker pin tube (opposite side of the breech face where striker pin pokes through). The caked on fouling buildup is hard and hard to remove. I soak the hole with Hoppes #9 with the striker pin hole plugged (10-15 minutes). Then I take a small flat screwdriver and scrape the softened fouling build up out (repeat soak if necessary). In all cases, the striker hit returned to normal and no more misfires, even with Wolf primers.Ived used a klot of Wolf and had no problems in my 1911, but the glock 45acp miisfires 30% of the time.
spelsh, this is THR and we sure try to be fair and objective. Reloading involves many components/processes and failure-to-feed/misfires/ failure-to-eject are often blamed on the wrong component/process. I am a long-time fan of Winchester primers but if Wolf/Tula/PMC primers are good, then we need to share this information with other reloaders so they know the "truth" about reloading components. BTW, for some reason, I don't see anyone trash talking Magtech primers from Brazil? Yes, I also use Magtech primers as SP feeds better in the quirky Pro 1000 primer attachment.I love the information on this forum. You can always get an honest, straight forward answer.
... you asked if it might be a fluke, a bad primer or two in the lot. Generally speaking, no. Modern primer manufacture in the US and abroad and especially in the Murom plant where the Wolf primers are made, is held to such a close standard that the possibility of a bad primer is infinitesimal, the odds of more than one are essentially zero. When misfires are experienced, the primer is generally the last place to look for the cause. I'm not suggesting it is impossible to have a bad primer, simply that the probability of that is exceedingly low.
