Without details like pictures of the groups, range setup, distance and conditions, no offence but it's still just an unfounded claim. Everyone's definition of accuracy is different so it's all relative.
With only the detail in the thread so far it's less likely to be the ammo than other factors; these include the gun, the rest, the conditions and your ability to shoot. We get you are angling to blame others but there are a lot of possibilities here which you are responsible for. There's also the elephant in the room which is a low count poster abusing social media for cheap competitive gain, or a disgruntled former customer. You see where I am coming from?
