As tempting as it could be,
My 175 SMKs have proven 25 rounds (split into 5 groups) in a row @200 sub 1/2 moa in that barrel.
Plus Jerry sells me them cheaper than any other retailer.
So yeah, there is better than Sierra out there for sure,
But for the price/availability/performance ratio, they keep my shooting at under 1$ a round for match ammo.
