A few weeks ago I was shooting at a mile for the first time, early morning sunlight on my target (I was laying in the shade of hill) and I thought this is amazing. I can see my score rings, ever so faintly, drawn with a sharpie. Millet 4-16. Now today my shooting group included a Razor 5-20, mark 4 10x and 12x Nikon binos. Conditions were: hot afternoon sun shining on light gray desert dirt to reflect some of the worst mirage I've shot through, winds blowing with no consistency, and the target, brown paper with marker, was facing away from the sun. I could not see the holes in paper any better with any particular optic, where the Razor clearly has better glass in "normal"conditions. My conclusion was that for any target I have a reasonable chance of hitting at long range, a 16x should do the trick no problem. Now a higher power scope has its place, but I think that place is on rifles that typically have a smaller caliber and are shooting tiny objects (or groups). So I would like to here perspectives from more experienced shooters than I, or any hunters' personal experiences on magnification.
