Yep. Started with .30-06 and .308 and .45 acp. Then .44 magnum. Then .357 magnum and .38 special. Then .223 (for varmints).
Stuck with those for years. I used to give away the 9MM, .357 SIG and .40 S&W brass I picked up.
Then I got a 9MM BDM, then a Glock M31, then a M&P .40 S&W. I built a .300 BO AR 15. Now I use all that brass I used to give away.
Powders? Still using IMR4895 (.308 and .30-06). Tried TAC in the .30-06, might be alright.
Still using Unique and Bullseye in the .38 special, .45 acp and some 9MM loads. Tried AA#5. Okay, I guess, probably won't buy it again.
Still have H110 for the .357 magnum. Used some Blue Dot, too, back in the day. Use it now for the .40 S&W and 9MM.
Still use IMR4198 for the .223 but moving towards BLC2 (yeah, another old powder). Tried TAC, best groups were below operating pressure in the rifle length gas system AR15's.
I've bought some new powder (800X - won't buy another can of that) and CFE 223 (never got the best groups with that one), CFE BO (haven't gotten around to using it, yet) and a newer pistol powder I can't remember the name of (haven't used it either, yet).
It's hard to justify buying "new" stuff when the "old" stuff still works so well.
Still using lead bullets, too. The old 1911's didn't care if it was lead or jacketed. A couple of the CZ's don't make the grade with lead bullets (a 1911 is 100% trouble free with lead, all of mine are, the CZ's may need bigger/smaller bullets than other 9's - what's with that??? Why are Colt 1911's made across 80 years more consistent than CZ's made across 10 years??) But buying some coated bullets the last couple of years, they do okay, but smell funny when fired.
Reloading is fun, mostly. You have a bad day/afternoon/moment now and then but all in all I wouldn't stop reloading till they park me in the dirt, some day.
