    I own a 300 Jarrett with a 25" 12 twist barrell. My favorite weight bullet for whitetail deer is 165 grains. Nosler ballistic tips, accubonds, and the Berger 168 grain VLD bullets always shoot sub .5 MOA. I have never been able to get the 165 grain Scirocco II to do any better than 1.5 MOA. Any suggestions, or does my barrell just not like that particular bullet?

    Does anyone have any experience with the 180 grain Scirocco II in the gun described above?
