Had an issue with Sierra Blitz 50 grainers and 50 gr Hornady SX in the 1-9" twist bbl of this coyote before I had Lee punch it Ackley, but that was with 9,000+ rounds down the tube and the throat was alligatored up pretty good.
40 and 50 gr Vmax haven't ever had a problem even with all the throat wear at 3,900 and 4,050 fps respectively.
