Browning A-bolt varmint stalker

I was wondering if anyone has one and what kind of accuracy can I expect. currently looking at one in .223 wssm? any experience with the caliber?

I have a 243 wssm in a A bolt and with lite bullet weight (58grain) at 4,000 fps i'm getting .75 groups with no flyers but haven't been able to come up with a good load for 95 grain bullets but as far as the rifle i like Browning alot , also check a site at www.wssmzone.com it is a pretty good site all about wssm's god luck
