Hand loading all the way in my opinion. Factory ammo is ok but if you want accuracy you have to tune a round to suit your rifle.
I get 1/2 moa at 100M (If I do my bit) using 69g SMK with 22.2g of N140 loaded 15 thou off the lands. Rifle is a .223 Browning A bolt tactical varmint with a 22" barrel and a 1-9 twist.
