I don't think its a bullet hole my guess they drilled a grommet hole so they could put a probe thru using a Maverick or whatever actually a pretty good idea its been done before did the same thing on my smoker those therms on the lid are not that accurate since they are not at grate level but to be honest on my performer I just learned to cook by the dome therm learn your grill no need.
