Do the math.
You go to the range once per week and shoot 50 rounds. That's 200 rounds a month, 2400 rounds in a year.
You go to the range 3x a week and shoot 100 rounds. That's 1200 rounds a month and 14000 rounds in a year.
And those are on the low side. If you do a gun instructional you'll run through 500-1000 rounds easy in three days.
You talk about ammo scarcity, but even if you just forget about that, just using the firearm(s) you shoot means you are probably going to want to have at least a year's supply, because buying in bulk is cheaper.
If you shoot three calibers or more then you sort of have to convert the spare bedroom into a gun closet and armory, lol.
I am of the opinion that less is more and we've cut back range visits to once every two months. It's sad because it's a hoot to perforate targets.
