Founder of the company I work for had a range built in the crawlspace under his house. The back porch had several steps down from the house. That is where the access and shooting is done for his target. He had a motorized line to manage the targets. There was a metal backstop at the other end of the crawlspace. He didn't let very many people shoot there because you had to hit at least the backstop.

He practiced and did the .22 championship target shooting and had some very specialized guns.

He also made a roll around backstop on a cabinet to keep targets, etc in. Used that in the company warehouse. It was a bit more forgiving with at 6x6 foot backstop. I've seen people shooting in the warehouse that had trouble hitting the backstop at only 25 yards. The wall behind the backstop was double cinderblock. Still kinda scary to me even though I myself had no trouble hitting the targets hung on the backstop.

That quickdraw stuff seems like a great way to shoot yourself in the foot or worse. Seen those guys just tilt the holster to shoot. But know it's a popular sport.
