SOLVED: First shot of each group low and right

[1Shot]

It could be the ammo. Shoot more than three round groups and see what happens. I have two Grendels and one HATES 123 SST ammo averages 3" at 100 and will not shoot any hand load with the 123 SST bullet accurately and the other rifle will only do about 1 1/2" 5 shot groups with it. Both rifles do MOA or better with hand loads. The Hornady 123 SST is the only factory ammo I have shot in them.
