I don’t know if your batch was different than mine.... But I definitely experienced a lot of white smoke (that smelled bad) and a lot carbon on my gun after shooting TuLammo - more than from shooting other budget “range grade” ammo such as Geco, S&B, PMC or Federal and CCI Aluminum case, etc. I also noticed relatively low powder charge - just enough to cycle my Glock reliably, but nothing like other “budget” ammo I listed above. Accuracy seemed okay, though, on par with other ammo.I've always heard that, but that wasn't my experience when I shot some the other day. It was decently accurate, too.
