So I’m in the breaking in point long and boring but just had loaded some junk 55 gr fmj with cfe223 and group was good moved to 62 gr jhpbt and it starts raining wind picks up and not even halfway done with break in and almost at 1moa with bad conditions so I’m sure it will be great shooter. I did notice Rifling is snug to my other barrels that I won’t name maybe because it’s heavier chrome lined? Will post pictures later with groupings when weather is better in ky
