I voted 101-200 and I suppose I shoot that many more often than not, but the fuller picture is that I varies quite a bit depending on what guns I am shooting, how many guns I am shooting, what range I am shooting at and what I am trying to achieve.
If I am out with my 45-70 Marlin 1895 with peep sight, banging steel swingers at the 100-yard berm, I will not fire more than about 65-70 shots in a day, and that is spread over 3-4 hours of shooting. Now, while I let the big gun rest, I may sprinkle another 100 rounds of 22lr offhand on smaller steel plates so that would raise the round count. Then again, maybe all I shoot that day is the 45-70.
If I am at the indoor bullseye club shooting national match courses with my 45, I probably will fire about 50 to 100 rounds.
If I am shooting 22lr benchrest practice, I may only fire 50 to 100 rounds.
If I am practicing my sight picture, trigger press and return to target for IDPA with my S&W 66, I may fire 300-400 rounds in a session in just 45 to 60 minutes.
If it is a day where I am meeting 3-4 buddies and we've coordinated to bring X firearms to have a little friendly match (and we have a few games), then I probably will fire fewer rounds because we are concentrating and recording shots, etc.
You get the picture.
