The other weekend I borrowed a friend's AGI Armorer's Course on Sig pistols. At the very end the Robert Dunlap mentions that fast-burning powders are quite harmful to the semi-autos, particularly to Sigs. According to Mr. Dunlap, the locking block gets deformed by repeated use of fast-burning powders in a SIG.
Have people seen any evidence supporting this suggestion? I was considering buying some Bullseye (2nd fastest in Lee loading manual's comparison chart) but now I am concerned...
Thanks,
