Went though a total of 350 rounds of ammo in about an hour.
Not sure when this happened

Nice collection of wheel guns! I'm guessing GP100, SP101, Uberti & S&W 686?
350 rounds of .357 will chew up your hands. I did a two day training course this past summer, and shooting only 250ish rounds of 9mm gave me blisters. You put a lot of lead down range in an hour!
