have a need for a fixed power scope strictly for paper and steel, most distances will be between 200 and 300 yards, but will also require going out to 700 yards. the rifle is a .223rem henry s/s break action. i've had and loved swfa ss 10x42 scopes in the past, for bolt rifles, but never went past 300 yards. getting another swfa s/s, but would 12x or 16x be the better choice? TIA!
