Re: SWFA vs Nightforce
I don't have enough experience with the 5.5-22x nightforce to say, But the Nightforce F1 is better than the SS by a decent margin optically.
I'm not sure if all new Nightforces scopes are better. I looked through a friend's Early F1, and it was not nearly as clear as the last few F1's I looked through. Or if only the F1 got the optics update.
On 15x, the SS's image at 800 yards is yellowish and hazy. While the Nightforce's image at 15x was crystal clear and bright. Not that the SS is bad, it's perfectly capable of shooting long range, but It leaves a bit to be desired in my eyes.
It may be sample variation, or maybe the new Nightforce F1's are clearer. But We compared a S&B PMII 5-25x, USO 3.2-17, and Nightforce F1 at the same magnification and surprisingly the Nightforce came in first. The PMII had slightly brighter colors, but the image was duller, and not as sharp.
I don't know if all of the new Nightforce scopes received an optics upgrade, or if the F1 is the gem in the lineup, but the F1 is the most expensive of their scopes.
I want to also mention that, looking at 100 yards, they all look pretty similar. But once you get to 600-800 yards, the difference is more apparent.
