Don't be too hard on yourself. I know of quite a few in my Gun Clubs that thought the way you did.
They occupied themselves with other activities they thought more important.
Quite a few people could not understand why I still reloaded 9mm. .45 ACP they understood, but not 9mm. Now they wish they did, and some like you, who gave it up when ammunition was less expensive ( I never considered it cheap), wish they still did.
For myself, while Reloading and the study of Ballistics was a very nice side hobby, used to feed the main hobby, I never forgot why I started doing it. Back then most centerfire ammunition was considered by myself to quite expensive. When times got better, I kept reloading. Too stubborn to quit I guess. But I was afraid that the era of less expensive ammunition might not last, and I actually preferred my own loads anyways. I also consider it a matter of self sufficiency.
At this time however, even if you still had your Reloading Equipment, you might find Components difficult to come by, depending upon local supply.
We have very few Gunshops left in my area and they have very little, if anything in the way of Primers. They have some powder and no bullets. Have to Mail-Order Bullets if I want them. Berry's Bullets, which are my favorite for handgun, are working a six week backlog.
