I have a CZ 527 American chambered in 6.5 Grendel. I like it a lot. It’s a sample of one and the only round that I’ve shot in it is factory Hornady 123 SST. It isn’t a tack driver. Probably 1.5” five shot 100 yard groups are the norm. It’s a nice old school bolt rifle IMO. I was lucky enough to buy it shortly before the closeout and before prices went up. I wish that I had bought a few more in other chamberings.
I had the exact same experience with mine using the Hornady 123g SST's. Switched to Nolser 120g Ballistic Tip and it IS a tack driver. Shoots well under an inch with the Nosler ammo. My new shop will be finished out this spring and I'll put the virgin Star Line brass to use then. Gonna try the Speer 120g Gold Dots. I hear good stuff about those.
