I like a few here didn't reload 9mm or .223 (except for the heavy more accurate stuff for my kids varmint/target bolt action rifle) because it was cheap to buy, hopefully those days come back. While I had a die I picked up cheap, I did not reload 9mm until a couple years ago - will prices and availability for primers get better? Maybe, but I am not holding my breath, until it does, I hope I have enough supplies to get me through.
When I first started reloading it was due to the cost of factory .45 Colt, did the CBA, figure out I could load my own and pay for the single stage, scale, etc in about 500 rounds. So, for me there was a cost factor initially, probably still is to some extent, now it is mostly about being able to create more accurate rounds for the rifles I like to shoot (223, 6.5, 243) and being able to have ammo to shoot when factory ammo is not obtainable (like the last couple years).
IF prices come back down, I am not opposed to picking up some more factory range ammo to add to the cache, if prices don't come back down, or primers and powder don't return to being readily available, then I have other options with stuff I have stocked up on over the last 5-10 years.
I do buy factory ammo though to answer your question, and lately for me it is factory .22LR or .22WMR I have not desire to learn to load rimfire ammo at this point and time and probably won't in the remainder of my lifetime.
For trigger time these days, I have been shooting rimfire and have assembled (purchased, upgraded, etc) a few fairly accurate rimfire rifles and scopes, I don't compete with anyone but me and maybe a little friendly competition with my son and friends here and there so no voodoo rifles for me yet but I have an RPR, a Mark II BTVSS, a Savage precision, and I have a bit of .22 LR stashed away in several different flavors of both .22lr and .22 WMR so I can see what shoots best in each rifle I have or purchase and go from there.
a .22lr at 100 or 200 yards with a little crosswind is a good trainer for shooting my bigger rifle at 500, or further, also I can spend several hours at the range and not burn up a lot of money like I would with the 6.5 or other bigger caliber rifles.
YMMV
