Adapt and overcome; here's what I did:
1. Went to caliper (223 Rem) that gives me a lot reload yield and trigger time for a pound of powder, i.e. 280 reloads per lbs.
2. For pistol, I went a fast powder (231) and moderate loads (38 +P) that gives me a high yield of about 1,200 rounds per lbs.
3. I wait for sales on bullets at my local shop or use Blue Collar Reloading. I try to buy in bulk (See comment 6)
4. I am not a blaster but a precision slow fire shooter, so I normally shoot 10 to 15 rounds per centerfire rifle range session, all cool / cold barrel shots because this is the "money" shot for me being a varmint / predator hunter. When not shooting, I enjoy the surroundings taking in nature and talking to fellow old fart shooters like me.
I score every shot.
5 Two years ago I went back to 22 LR to increase trigger time. I purchase a Tikka T1X. Great move for me. My typical range session is 30 rounds so I get a lot of shooting out of a brick of CCI Standard Vel ammo. This ammo is good enough for me and my intended purposed, trigger time and practicing fundamentals. I score every shot.
6. I get good mileage out of my reloads for my purposes which is practical shooting at the range, which is fun for me and hunting, which I love. I don't do any extensive load testing / bench shooting / experimenting which I hate. I have fun which I love.

 This approach allows me to buy in bulk since I have all my loads established. In addition, I have a few alternative powders when supply chain issues arise although I must admit, this is getting more challenging.
7. I do not buy expensive cleaning products. I have learned through experience that I can achieve the results I need with simple, inexpensive solvents. I blame this approach on Elmer Keith, Page 306, "Six Guns" and Jack O' Connor.
Aside for that, there isn't much I can do. We have no control over the supply chain or pricing. If you are innovative, you can stay active, at least for now. You can't predict the future? Carpi Diem!
