I don't particularly like Tula and other cheap steel case ammo because I feel it is loaded soft, and is a bit less accurate than more "premium" ammo lines, not to mention inherently dirty. I very rarely shoot standing still at a regular range these days, and have gravitated toward action pistol shoots. For that purpose, quality ammo is just better for me. Fortunately, I live in the tax free state of DE and can get Sig Sauer FMJ, PMC Bronze, Magtech etc all for less than $12 a box (50), 124gr NATO Ball (10% over pressure) for $14/50 rounds, and American Eagle 100rd packs for $18-20. I can also get some even cheaper brass stuff such as Perfecta, Herter's, Federal Aluminum etc for under $10/50rds if I chose to. All of this is regular retail in stores. At those prices, it doesn't make sense to me to venture into steel or surplus 9mm, even though I shoot a minimum of 250 rounds per week in 9mm. That being said, I have put a few boxes of Wolf and Tula 9mm through my SD9VE without any failures or issues, I just personally didn't like the overall performance of those products. For rifle calibers though, namely anything not shot from an AR, I shoot quite a bit of steel case Tula, Bear, Wolf etc with good results as well. My AR's seem to also digest steel case Ammo just fine, but I only feed them brass with an occasional few boxes of MFS Zinc coated steel case ammo when it's in local stores soley because $4.50 a box for decent shooting .223 is a great buy!
