Am I correct in my understanding that dry firing a marker is less efficient on air than with paint? I am speaking about an Automag specifically. When teching my Mags, I notice that they seem to blow through a lot of air when I am just dry firing. I can take a 48/3k tank and empty it is what seems to be a few hundred shots at most. Not a huge issue except air fills are an hour a way and gets costly quick. Would covering the barrel/feedneck create back pressue that would make it more efficient when doing this?
edit- I know about using scubas, shoebox compressors etc. not looking for ways to get more air, just ways to make what I get more efficient when teching.
