I've shot a lot of stuff through mine. Lots of Remington Golden bullet, Federal bulk pack, Winchester Super X and bulk, CCI Blazers and mini mags, probably others I can't recall right now. I haven't really had any problems. I can recall a couple FTE with the Federal, but that's about it. Blazers and mini mags seem to be the most accurate in my experience. All in all, it hasn't been picky about anything. Eats it all
So far, the Federal Premium Gold Medal Ultramatch have been the most consistent out of my TTD, unsuppressed. Federal bulk match, cci-mini mag hp, not so much. Will be trying a few other less expensive options in the near future.
