I'm wanting to get a stronger scope for longer distance shooting (100+ yards). My MTC 5-20 is great to 50 and 75, but only OK for 100. I've done a bit of research and want to spend $300 - 350 max. The two scopes I've narrowed it down to are the Aeon (great recticule choice) and the Mueller. Would appreciate any feedback from those of you who own either one. One specific question is how can the Aeon scope at this power be so short?
