STP Sterling 12 gram efficiency?

[Guest]

Hey guys, how many shots do sterlings get off 12 grams regulated or unregulated?

I have not done any serious testing, but I get about 30 shots from mine. I don't have a working Chrono, so I would say about 30 usable shots before velocity drops too low. If you really need to know for sure I can slap a 12 gram in mine and get a specific count. It is on par with my Phantoms, I know that for sure.

I get a lil less then my Phantom but more then my Sniper 30-35 depends on how fast I’m shooting.

Last time I ran a Sterling on 12g I was getting 25 solid shots, 5 usable, then a steep drop to the point where it was about useless. This was with velocity around 280fps and using an underbored insert.
