Friend of mine had one he used to shoot in IHMSA. Don't know how many round he shot thru it, but let me tell you, they were a bit over book max. He finally sold it to another friend, and he shot loads probably even hotter. Never had a problem with the gun, and it shot lights out. Probably still going the last 25+ years since the other guy got out of IHMSA(too boring, always shooting 40's in about every class he shot).
