Still have a couple 99's. I had a couple auctions and scaled back (Old age), but just could not get rid of the 99's. A .300 is good. I call it a medium round. Does not kick much, usually really accurate, and hits deer hard. I use Remington corlockts in mine. If you look around, the .303's are usually cheap because ammo is scarce. Graf is making brass again so it would be a deal if you come across a cheap one. I still use mine once and a while.
