i have used both sizes extensively for s.b.r.'s and other stuff
my logic was to hit a man sized body at 400 yds on demand form a bi pod
it does it very well at long distances it is not a 1 m.o.s. scope but itis a 3-4 m.o.a. i liked the point at the top and shot it well on a 223 for several years
also i could use it as a contac distance scope if i need to and it gave me flexibility near and far.
i kept selling them off my gun at shoots and replacing it as i am a trijicon dealer ans always have 1 in stock.
i went to a higher grade scope in vison and flexibility and to shoot further.
i never felt under powered i just wanted better glass to shoot further a bit more accurately. it is NOT the 1 m.o.a. glass for 5-600 yds but it performs admiralby out to 350-400. my web site manager is a nationaly ranked sillouette(?) shooter and he has 3 for all kinds of stuff
my breathing and eyes preclude me form doing much better but a young person probably could
ask i am around & good luck

p.s. i used it BEFORE i was a dealer or before i openrd outdoor specialties, in 1999. a vey famous shooting instructor (and friend and business associate) said this: if u can only have 1 scope this is it,he had never seen 1. it is so much better than an acog it is not funny.
it is not well known but a great choice
