I've shot about 500 rounds of the stuff. VERY dirty, but no problems. Laquer never melted, steel caes didn't rip my gun apart, no FTE or FTF.
I would use it for target ammo, but I've switched to the Winchester Q3131A. Don't have to spend 6 hours getting all the crap of the my rifle after every range session. Plus it's not that much more expensive.
