Here's my take on this, which I think OP can relate to because I was in the same situation not too long ago.
What is your concept of "volume shooting" and here's how I'd break it down.
Question 1: do you go through 200 rounds or more of 9mm each range trip and do you go to the range more than once a month.
Question 2: is reloading to you a chore, or another hobby?
Initially I wanted to load a ton of ammo on an XL650 or some other big progressive but as luck had it my dad had purchased a Lyman turret press kit a few years ago and it had sat unused so in the interest of saving money, I decided to try cutting my teeth on a low cost/no cost option to see if reloading was even my thing. Turns out it is and I love almost every aspect of rolling my own ammo. Here's where things got interesting for me.
I'll shoot anywhere from 400-1000 rounds of various ammo per month depending on life and the season, and I realized that if I just sat down and crushed out 5000 rounds of 9mm in a week, I'd have nothing to reload for all of my calibers and I'd have just an idle hobby sitting around for a few months or more waiting for me to deplete me stock pile.
So I'd look at it this way.
Money to spend/confident in your purchases->more than 300 rounds per month->it's a chore= get a progressive
On a budget/unsure of reloading->500 rounds per month or less->reloading is an enjoyable hobby=single stage
For what it's worth, I'm running that Lyman Tmag 2 turret press for my 9mm, 45ACP & eventually 223 plinkers as well as a Lee classic cast for my precision loads and can comfortably load a sufficient amount of each ammo for my purposes each month, but again I enjoy the process so it's not like I dread spending hours per week loading my ammo.
