Wolf works fine for me.
Tula has been a problem.
Also avoid Herter’s (Its made by Tula)
Thanks for your comments of your experiences. My followup with my RRA LAR15:
First off, some time back I tried TulAmmo, futile, every 3rd round didn’t feed.
I ran 40 rounds of the Wolf WPA .223 through it today. Worked perfectly. Groups were nice.
I did note that the finished appearance of the steel cases was much better than the TulAmmo. I also did a thorough cleaning when I got back from the range. I went ahead and grabbed 200 more rounds to try in the next few weeks, weather permitting. I usually run 40-60 rounds through the AR per session. I’ll try to follow up after another session or two.
