WBM, as you can see by my number of posts, I am new to CF rifles.
Well then since you're new, let's get to "bottom lines". 223 ain't the way to go with long range...sorta like scratching your back with a claw hammer...can be done and it works but you're glad when it's over. Long range is better done with 6mm. You can buy a Savage already chambered in something like a 6mm Creedmoor and be way ahead of the 223 stuff AND probably spend less than with a "custom super duper barrel."
