Edited my first post,

Since the SWFA SS 16x42 is back ordered until July, could I drop down to a 10x or 12x, and still effectively hit MOA at 500 yards? I know I was told to buy a 16x as minimum, but is it worth the wait? My budget was under $400 for rings and scope. I got the SWFA 16x42 with Burris XTR rings, and badger covers for $386. Should I shop around for something else, drop down to the lower power, or just shut up and wait?
