My range is a one hour drive each way -IF- the traffic is friendly. That means I cannot go as often as I would like. Once a month or every six weeks if life is hectic.
Add all that up and it’s easy to see that my routine means 7 handguns minimum in tow, some times it is 10 or 11. If the weather is decent, we never do a session under 6 hours. We’ve done 8-9 hours many times.
My log knows for sure but in centerfire, 900+ is typical. Rimfire is usually between 200 and 400 rounds. Sometimes the rimfires don’t come out. Living where I do, there are some months that are just a no-go if you want to enjoy the experience.
So yeah, I do long, long days with high round counts. Also typically cover 4-7 different calibers.
