Back in the early days of IPSC shooting, there was a wry observation: “You spend your first hundred-thousand rounds learning to shoot. You spend your second hundred-thousand unlearning the bad habits you learned in the first hundred-thousand.”
Yes, we used to shoot that much, and some still do. We have learned a lot of things since then, one being that you can master the same skills with half as much ammo. Part of that is due to a heavy emphasis on draw and dry-fire practice.
Yet despite ammo prices coming down, it still costs money. Add to that the time to get to and back from the range for each practice session. Then there are the days of inclement weather.
