I bought a 2.75 chambered nitro-proofed Tolley SLE to use with the Fiochhi low recoil training loads (or similar shells) and cut down on ammo costs. Those are now impossible to find as well. Fortunately, there are other options and this gun digests them without issue.

In any event, the whole point was to avoid being limited with vintage guns to RST, the only reliable supplier.
