Are you asking about their 350 legend specifically (per your link) or POF generally?
As far as accuracy, 350L is a straight walled cartridge so don't expect 762 or 556 "match grade" accuracy. consistency in loading the cartridge is as important as the rifle & barrel. factory ammo QC sucks balls during the pandemic, they seem to be happy to pump it out even if it looks like a hipster loaded it in his garage on a single stage.
