That's a good question and I don't know the answer but will tell you what I do. I don't even shoot the bullets I pull myself. With all the time I spend focused on all the other parts of reloading, with accuracy being the end goal, I don't want to deal with issues that could be introduced by pulled bullets.
Are there issues? I have no idea, but others with more knowledge of the subject may say they are fine. Certainly possible I just imagine they could introduce accuracy issues.
I don't think there is any adverse effect on the terminal ballistics or when working uploads for speed/pressure testing but will stand corrected if needed.
