Nosler Competition bullets....as good a Sierra?

I shoot the 168's and my rifle likes them at 100 yards better than anything else however farther out they aren't so great. I've shot a few of the 175s but they didn't shoot very well however I was trying some once-fired FGMM and Win. primers. That was a bad combo. I think that the Nosler Custom Comps are good bullets.
 
I get up to 0.007" variation in my oal using 175 SMKs that I do not find loading either Nosler Ballistic Tip (165 & 180) or their Partition 180 bullets.
However they all shoot sub MOA out to 300 with the right powder.

K.I.S.S.
