Tula ammo
I have fired hundreds and hundreds of Tula ammo in .45, 9mm, .380 and .223 through many various guns, its my "go to" ammo to function test anything I buy or trade for, I have NEVER had a single round of Tula in any of the calibers I shoot go "click" instead of BANG!
I also have never seen a failure to discharge with Tula ammo with any of my friends that use it either, this whole thread of Tula having hard primers, etc. is all news to me.
Tula is the DIRTIEST ammo I have ever used, but I dont care, I only use it for function testing new guns and new mags, I am going to clean them top to bottom inside and out as soon as I get home from the range anyway, and as others have said, accuracy is actually pretty good with Tula, at least in my experience.
For the price, even though it is dirty and at least in some peoples experience, not 100% reliable, its fine for the range use, just make sure your defensive mags are loaded up with something higher quality.
