I have a stainless No 1 in 35 Whelen with an MPI stock. I replaced the sights with the V notch rear and large white dot front sights off of a 375 Ruger Alaskan. Shoots right to POA at 75 meters.

Warne makes decent QR rings and I have a set on the 35 Whelen with a Leupold VX3 1.5-5x20. I think this combination works really well

I had another in7x57, a light weight and I used a NECGS peep sight with a gold bead front, it shoot well but I never took it out of the gun safe on a hunt. I wonder if that is telling or not?
