WTB 30 Remington Ammo

I want to buy at least one box of 30 Remington ammunition. Not 30 Remington AR. 30 Remington looks like a Winchester 30-30 round without the rim (rimless). Want to use my Grandfather's pump 30 Remington to hunt with this year. I just need a box of ammo to site the gun in and hunt. With the ammo shortage, those companies that make the obsolete round (Like Buffalo Arms) have been out of this caliber for a couple of years.
