You'll need to up your game in 2021. I have 6 tabs open in my web browser at all times; one is ammoseek with appropriate parameters set, the others are set with the appropriate search parameters for the bullet I was after. After I set up those tabs I saved my browser settings to always open with those tabs set. I check multiple times/day and after a month, bullets hit two suppliers and I bought what I needed to last me several years.
For your ballistic tips I would also set a browser to open on Noslers Shootersproshop dot com where they sell blems. I bought a pile of brass there over the last cpl weeks and that caliber still hasn't showed up at any retailer.
