Hmm, my information is pretty out of date then. I was just trying to get a rough comparison. What you say about modern high velocity CF re-inforces Gary C's point that airguns are mortars by comparison.
I have to remind myself that Pellet/bullet drop is only half the story . .
Seems to me that whether the scope rails need to be inclined depends not only on the pellet/bullet drop at the zero point, but also how far away that zero point is.
The nearer the zero point, the more sharply downward the scope needs to be angled.
Extreme case: 12" drop zeroed at 50 yards is like 20 *FEET* drop at 1000 yards!
Comparing to the old .308", the airgun would have to be dropping only 2" at 50 yards to have the same scope angle as the .308" zeroed at 300 yards. In practice a legal airgun will be dropping 2" by 25 yards, I reckon.
So, if you zero your FT airgun at 55 yards, a fairer comparison is a .308" at 600+ yards or probably somewhat more (the ballistics of the supersonic bullet will be far better than an airgun pellet), or perhaps a more modern CF at 1000+ yards, as you say?
