Thanks. I anted to put a badger rail on. But, definitely don’t want to spend the $ if it won’t fit properly.I seem to remember differently. The spacing was longer front to back, and therefore if I wanted a sloped base, I had to buy a Warne made for the Nosler. 0degree 2 pieces would be fine. Sloped 2 pieces would not line up but would install. Maybe it has changed or maybe it was just my long action. Mine is an M48 Long Range in 28 Nosler.
