The first thing I would do is try a different ammo...not all rifles shoot all ammo equally. Plus, core-lokt's aren't the highest quality ammo out there...I've only ever had one rifle that shot them well...a Marlin Model 336 30-30. Go buy 2-3 boxes of different branded ammo and try that...any premium ammo loaded with a premium bullet is where I would start (Hornady, Nosler, Federal, Wnichester)...while some people will claim Core Lokt's are ok (and they might be) it doesn't mean they will shot well in your gun. Finding the ammo your rifle likes sometimes is easy...other not so easy. I have a Savage Model 99 in 308 that I hand load for that took me ages to find a load it liked...on the other hand, my Tikka T-3 Lite in 270WSM has shot everything I have put in relatively well.
