Remington made plenty of pump action rifles. The remington 7600 is offered in your desired 30 cal. the 30 calibers thatit is offered in are .308 and 30-06. The 760 is also a pump made by remingtonand offered it in 308 and 30-06 as well. There is also the model 6, offered in the same.

There are also many other calibers that have been offered in these models that are good too. .243, 270, 280, and even the 35 whelen and 257 roberts has been offered.

If you are looking even for further choices, remington offered other pump rifles before these. They had the model 14 and model 141 and they were offered in 30 rem., 32 rem, and 35 rem.

Alot of guys have put see-through scope mounts on the model 760 and 7600 models.

hope this helps or atleast can point you in some positive direction. Good luck
