This stuff shoots fine in my SKS. The FTF rate in my Mini-30 is greater with Tula than any other brand. Mini-30 owners should opt for Silver Bear of Golden Bear. With the Wolff XP hammer spring in my Mini-30, it shoots the Silver & Golden Bear flawlessly, but still fails to fire the Tula 30% of the time. Sorry to have to report that. Wolf and Brown Bear will fire without issues, but do not load as smoothly as the Silver & Golden Bear. That's my experience.
Tula has worked just fine in my Ruger bolt action (Hawkeye) .308 and I've not had issues with it anywhere other than the Mini-30.
