The Bullet is 2-stage; I never run the thing maxed out, but some might. The spec for just the inner stage is 50 scfh of oxygen, but again that's a maximum and usually it will be much less. As the man at the factory told me, "we designed it so you could really push it if you need to." OTOH, the burner face is only about 0.53" in diameter so we not talking any Kobuki here!
Dale- Thanks for the tank cross reference. Remarkable lack of standardization there! What really hits me is with the increase in pressure and the slight increase in size, that "300" tank looks quite desirable if one can handle it. Dang arthritis
