I have to agree both are good. I'm betting he's looking for a way to get the best of both worlds though. ive debated this amongst myself in the past wishing I could have 22-250 performance with the cost of .223 theres two routes you can go 1. start hand loading and 2. if you only intend to use factory loads, get a loose twist .223 chambered rifle Remington and howa and a few others make loose .223's with a 1 in 12 twist and use 40 to 45 grain ammo. this way you will get near 22-250 velocity and trajectory from a .223 and don't have to worry about over spin on the projectile which with light varmint projectiles can rip them apart in flight from excessive centrifugal force caused by tighter twist rates.
