OK I need a little incite, I tried the search but didn't come up with any thing. I am wondering can you have to much magnification? the reason I as is I am looking for a scope for my new .223 and started thinking NF 12-42x56. I also have been looking at the st-10 from USO. So this got me thinking about how much magnification do I really need so please school me on magnification and its uses or show me a thread that does thanks!
