Scope power depends on the intended use of the rifle. For plinking and hunting , a 4x12x40 AO will be plenty . Actually for hunting , a 4x or 6x is fine for me. For target work it's different IMO. When I first started shooting field target, I shot hunter style exclusively and was limited to 12x power max. I usually shot less than 20 hits out of a 50+ target match. In October , I bought a Bushnell Banner 6x24x40 and put it on my TX200HC. That month's match, I shot a 25 out of 52 , the next month I shot a 39 out of 54 targets , on a tough course, on a windy ,cold day. So , the extra power did help me improve my score in field target. Someone at the club once told me , you can't hit what you can't see. Some of the targets have small kill zones and after only a couple of shooters the orange paint gets knocked off the KZ's and without the extra power , you can't really make out the center of the kill zone. I'm actually thinking of going to a 8x32x40. Some of the guys shoot 35x scopes and up to 50X . It all depends on what you're going to be shooting. kirby
