My brother had one in 30-30. Nothing special, really except you could load spritzer bullets when you reloaded. That improved performance some.
Weatherby: The ammo you show is not for the 488. It is for the model 8, 81, etc autoloaders. It is also known as the 30 Remington. It was (sometimes) referred to as the "30-30 Remington auto" (or "auto Remington") because of its use in the autos and because it duplicated the 30-30, which was very popular. Similar cartridges were made in 32 auto and 35 auto (35 Remington).
To confuse things more, I think Remington did also load a rimmed 30-30 that was different from the Winchester 30-30 (It MIGHT have been Marlin....)
