Just got my new upper it is a .223 1/9 twist, broke it in with 2 boxes of real cheap winchester ammo. Now I would like to see what this upper will do for groups, This is my only 1/9 twist rifle so I was looking for some suggestions on where to start in reference to bullet weight and brands, I do not reload so it has to be factory ammo maybe your opinions can save me a little time and money. Thanks oh yeah it is a REDXARMS 16" ss bull barrel.
