Hi Bruce, its probably worth adding a swept volume column to save calculator punchingOriginally Posted by brucegill
Ok, added SCR's for the rifles listed so far......
Can someone check my figures? I'm getting confused! (Have made a spread sheet up so its all automated....)
Looking at the SCR for say the early 77 and the 80, the 80 should shoot nicer than the 77Or at least it's closer to the preferred 300:1-500:1
I'm guessing Piston weight must be playing a major factor here!
The SCR is difficult as the target value depends on port length as the gas flow through the port is restricted more by a longer port, it's an indicator of when it will slam or bounce.
