A 10 or 12x scope for 1,000 yards.....seriously? You must have 3x eyes if you're accurate with 12x at 1,000. LOL
Depends on the use at 1000. From what I've seen BC post in the past concerning his intended use, I don't imagine he will be doing bench rest competitions.
A man size silhouette at 1000 doesn't require a 36X scope, nor does an 18" gong.
I could be wrong, just making an assumption from what I've seen BC discuss in the past as far as rifle purchases go.
