Absolutely. One school of though is that the Cushion of air trying to force it's way around the BB, stops it from contacting the sides. But either way, if the BB was contacting the sides of the barrel, it's trajectory would cause it to slide along the inner barrel for a short time. Not bounce back and forth a bunch. It is possible I suppose for the spin put on the BB to also hold it against the top or bottom of the barrel, the whole way out. I don't know for sure, I'm not a gymnast. But, something to think on anyways.
Also depending on BB weight, velocity, and barrel diameter you may have a bad combination. Tighter isn't always better. There is kind of a balancing act.
