Can anyone tell me what size Butler Creek flip-up to order for the objective of my Swift Premier 676S scope?

What is the outside diameter of the objective bell?

2-1/32". Should I get a #31?

I calculate 2 1/32" to be 2.031" According to my BC chart, fit can go .01" under and .025" over. A number 31 measures 1.998" and .025" over that would be 2.023". You are over that. A number 33 (no 32) measures 2.043" and .010" under that is 2.033". You are just barely under that one. According to what they have listed, none of them will work for you. How did you measure the bell? Did you "eye" it with a ruler, or use vernier calipers or a micrometer? I would use the vernier calipers and get an exact measurement (to thousandths if possible). Then you should be able to tell which one you need.

Heh heh....those things really amplify Weatherby eyebrow. Found that out first time I fired my .378

Mine's on a .45-70. Gives me a sore shoulder but the scope's got enough eye relief that I don't have to get that close to it!
