Not a 243, but I have Vanguard2s in 223 and 6.5 Creedmoor, all 3 are good shooters, with one of the 6.5 Creedmoors being probably the best shooting out of the box CF rifle with factory ammo, Hornady 140 grain AMax, that I've yet to own. The RAR-Predator in 204 Ruger that I recently bought is also amazingly accurate with Hornady factory ammo, sort of the chicken and egg thing.
