SteveieP Posted May 7, 2008 Report Share Posted May 7, 2008 My personal theory is that there has got to be an optimum weight for a pellet Too light & it will expell too easily without creating a cushion of air to stop the piston slamming into the end of the compression chamber Too heavy & it will take some expelling thus taking it's toll on the spring. American chap "Charlie Da Tuna" reckons the optimum is around 15 grains for a .22 Personally, I think there's a sensible range from say Accupels at 14.3g to AA fields at 16.0g which covers most situations just fine. I view Bis' Mag's as unneccessarily heavy unless you're FAC but then I'm a "no such thing as over penetration" kind of guy. Why settle for one hole when you can have an exit wound as well?
