Level 7 vs. Level 10 air efficiency?

[djinnform]

I used my Level 7 for most the day yesterday in hopes to see a jump in air efficiency. I didn't notice much of change. Can anyone estimate how much less air the Level 7 uses vs. the Level 10?

Somewhere on this Forum Tom says it's one shot out of 60 or 100? I can't remember, but my experience lines up with yours, I've never been able to notice a meaningful difference.

The difference in efficiency depends on what barrel you are using. Each bolt is more efficient at a different barrel length than the other.
