I've taken a few head shots with my .204R under spotlight with a bushnell set on about 12X at over 200m and it's not an issue if you have the confidence in your set up.
As long as your current rifle/scope combo is reliable and accurate I see no reason to throw money at new gear just to stretch its legs a little, by that I mean don't blow $2K on a S&B just to ghi from 200 to 250m shots, esspecially if your shooting under light.
Try and get a bit of time behind it from a probe set up (that is not from the ute mirror) and shoot some groups at 200, 250 and 300m and see if it's shooting under say 3-4" go smash them.

Thanks for the feedback, I think you are right. More practice time behind the 223 and more confidence at those ranges, I am still going to look to upgrade the scope to something a bit better though. I see some good prices on Zeiss HD5 scopes and I tried out my mates Meopta Meopro on his Sako on the weekend and the difference was noticeable. My Bushnell is a hog hunter scrub scope so probably not really ideal for longer range shots.
