Recently had 2 failures that came to light when I uncapped 22 oz bombers. 2 others from the same batch were fine. Can the bottle capper go bad? It appears that air got in there because inspection revealed that there was residue about 1/2" above the level of the beer so it appears that air got in. Both bottles also broke (small chunck of glass came off the top). I have capped approximately 30 cases with this capper.
