7.62 in Target shooting circles, normally refers to the calibre 7.62 x 51 mm, ie the 7.62 nato round, dimensionally identical to .308 Winchester, sometimes mistakenly referred to as .308nato.
7.62 is the most common traditional target round and extremely effective when used at ranges up to 1000 yards.
If you are a Newb to target rifle shooting and you have a hankering for a .223, then I would recommend a decent bolt action rifle with at least 24" barrel with 1 in 7 twist and a 5.56mm chamber. (5.56 x 45mm is the military equivalent of .223 and can/does run higher pressures)
As for 1000 yard shooting with the .223, just make sure you can consistantly hold 0.5moa at 300 yards first.
