Light bullets go faster but the Ballistic Coefficient (B.C.) is much lower on a light small short stubby bullet than a long skinny sleek bullet with a high B.C. The higher B.C on the heavier bullets provide less wind drift and even less drop at the longer ranges.
Compare a 22 caliber 40 grain bullet BC(0.200) to a 40 grain .204 (0.275)the B.C is higher on the .204 bullets thats why its more effective and efficient compared to the 22 Caliber lighter bullets. But move up in weight on your 223 (you can since you have a 1-9) like a 68 grain match bullet B.C is 0.355. Or if your rifle can shoot the 75 grain A-max 0.435 (some 223's w/1-9 can't stabalize a 75 grain a-max).
Those kind of B.C's are what you are looking for, If I didn't reload I would check out Black hills ammo (Midway stocks it) They offer a huge variety of match projectiles
