I tried the 140 Match Burners a few years ago with good success. My review on them might still be on here, but that might have also been when we switched to Scout. I don't have any of my load data from testing on hand, but I'm fairly certain it was in the usual "42 grains of H4350 in Hornady brass" range and MV was in the mid 2800s. They shot well enough, but i had some issues with really inconsistent bullet lengths, like a 0.010" spread, so my seating depths weren't consistent. It may have been a bad lot, but I bought a few thousand 140 ELDM shortly after trying the Match Burners and never went back. If you shoot any 6mm calibers, their 112 Match Burners are fantastic!
