Do you think that the NSX is too big on your Sporter??
Since my sporters are used for mid range hunting in tighter terrain under 600 yards, I prefer a lighter, smaller scope then the NXS. I personally like the NF 2.5x10x42 or a scope in a lighter, smaller package. The combination of a accurate turrets, great glass, and the velocity reticle make this scope a perfect balance and look on my Model 70 Super Grade.
