I see alot of the old Rem.rifles, chambered in the 30 Rem. I looked in my reloading manuals and the cal. isn't even shown. Is this cal. about the same as the 30-30Win?

For reloading use 30/30 Win info. The 30 Remington is just a rimless 30/30 case. Same goes for the 25 Remington use 25/35 Win info and the 32 Rem use 32 Win info. All three are the same basic case necked to the different calibers, 25, 30 & 32.
