Yes I have had rifles that just would not shoot even after bed, trigger and crown.
I always start with Sierra MK's because if it won't shoot them then it isn't going to shoot anything else.
For load work I always use a target scope of known quality.
HOWEVER if you don't want to waist time and money bore scope the barrel first. I would look for missing rifling. I have seen several.
