Even after Taurus fixed my PT745 for the 3rd and final time and got it just about perfect, it had a couple failures to fire with WWB. I have been getting a low opinion of that ammo. Much like Wolf ammo, it seems to have hard primers like military ammo often as. And I believe that Taurus designed the PT with just enough firing pin power to pop a regular primer vice mil spec ones. That, to keep trigger pull effort down. And for a DA only pistol, I do really like the trigger feel on the PT. They got it right.
And getting too much oil in the firing pin area will hydraulically lock it as it moves forward and lead to failures to fire as well. I flush that area out with CLP to clean it after each range session. (And clean the rest of the pistol as well.) But then I blow it out with compressed air to get out excess lube. A very light touch of grease on the rail contact areas and it's all set for next time.
I find if I run Aguilia or PMC or S&B as well as the Federal HP ammo it runs 100%. I tried some American made stuff that I can't remember the name of. Gunshop had it on sale. (I shoulda bought more!) It ran 100% too. But put WWB and you'll have a few failures to fire in a hundred rounds. Use Wolf ammo and you'll have even more.
Funny thing is I can use WWB or Wolf in my XD45 with no issues at all. All I can figure is that it's design allows the firing pin to strike the primer with more force. But then my XD is my only pistol that eats Wolf ammo with no issues. That amazes me! All my others get indigestion on it from one degree to another. I like Wolf ammo for my AK and SKS, but I don't buy their pistol ammo anymore.
I've asked about WWB on some boards and near as I can figure it's just ammo made by God knows whoever Winchester contracted it out to. Winchester doesn't make it. They farm it out. (If I am wrong on this please prove it to me!) So I stick with the better ammo in my PT and it runs happy and doesn't let me down.
Shot one magazine of WWB JHP and had one FTF. I then shot Two magazines of UMC and had one FTF. Any ideas why my gun did this. I even pulled the trigger multiple times on the WWB and UMC and they would not go off. I was able to reload the UMC and then it went off, but the WWB would not go regardless of what I did.
