Hopefully, B & P will once again offer these 2 and 5/8s #7 16 gauge shotshells in the future. They do have 12 gauge 2.5 inch shells available in their Upland Game Classic lineup. https://baschieri-pellagriusa.com/hunting/upland-game-classic.html
It is odd how ammo suppliers come and go in this market. A few years back we got Aguila shotshells by the truckloads, loved them and they shot well. Now....none in my local box store. Just like Cheddite primers. But we do have some low-name-recognition new versions in the store by obscure makers/suppliers, but they are all > 1300fps so not legal for 12-ga trap.
