Bolt Action Scope Mounts

[Jarhead]

Weaver Type One Piece vs Weaver Type Two Piece vs Leupold Standard Dove Tail vs Leupold Double Dove Tail?

Steel or Aluminium?

For Varmint Rifle.

Which do you prefer and why?

I have a strong preference for a one piece picatinny base. That allows for a pretty universal option for your scope mount.

^^^This. It also helps to minimize alignment issues between rings.

What they said.

But...

Out of the choices you mentioned a Leupold double dovetail in steel would be best....but they are a tad finicky about getting the rings perfectly straight.
