vise will go onto a granite surface plate that's been leveled in all directions.
So I will level the rifle in a vise with my machinist level (Starrett Master) accurate .0005 on 10in
Once leveled, hang a plumb bob. Install bottom of rings, Mount scope with eye relief. Tighten lower ring to rail.
Mount scope loosely tighten rings evenly enough scope can rotate. Shine light through objective, rotate scope to align to reticle against plumb bob. Cross tighten rings slowly, verify no change in alignment.
Once done double check, then check reticle alignment viewed through objective as a double check.
Go have fun this weekend.

Stick is a McMillan fiberglass stocked, Remington 700bdl, Hart Stainless heavy barrel in 300 win mag, With Steiner Optics in mil dots. I'd love S&B, but that price tag....
