Every rifle is different, so what works for someone else won't necessarily work for you. My best advise to you is to look in your reloading manual or online for a starting load for the caliber/bullet you want to shoot, & work up from there. Starting loads tend to be more accurate than max loads IMHO, but you may have different results. Pay attention to things like good brass prep, measure the distance to the rifling for the bullet that you intend to use. Neck sizing fired brass also helps accuracy. Seating distance from the rifling will affect your accuracy also. Good luck on finding that accuracy load for your .222
