In cases where I've not quite hit depth with the empty bar (think within an inch or so of depth, not half squats), it was with a bar-only warm-up, and was due to the fact that I was not warmed up. Usually by my 2nd warm-up of 45lbs or maybe by 95lbs, I am at full depth, and if I were to go back to just the bar, it would be full depth. The issue here is NOT that I can't/don't go full depth with just the bar, it's that I have yet to perform the task that prepares my body for sets at full depth - the warm up. Also, I'm not advocating warm-ups at less than full depth. There's a good argument for not going beyond just the bar before you are getting full depth. For me, I know my body and know that if I didn't get it with just the bar, it will be there the next set.
