Weatherby Ultra Lightweight? 5.75lbs in .270 thought about this setup for a lightweight sheep rifle type setup.

doesn't rem have a mountain rifle in .270 now?

Gm54-120

New Ultra Light Arms model 20 weighs about 5lbs. I doubt you can find a light weight that shoots as well as a NULA. You wont get one for anywhere near $800 though.
