Me enjoying the power of Israeli Military Industries:
ETA: 200 rounds of 5.45 (just the wife) and about 800 rounds of 7.62x39 in just a little over an hour, including breaks for the .44 and my blackpowder, along with a few other guns not pictured. Not sure but I think that might be a new record for me.
