I took 100 pellets at random
lead (from an old Remington express load) weight =315.3 grains
NS - weight = 281.8 grains
so NS is a little less dense - roughly 90%
size - i took three pellets
lead averaged .128
NS averaged .125 a PS - 97% of the lead size - so not enough to cause the weight/density variance
I am guessing ducks will not know the difference assuming equal velocity
I am NOT cutting a Kent TM open for this
but according to other testers - TM is 10.8 g / cc and lead is 11.35 g / cc
so TM is about 95% as dense - pretty close to NS
ok - found this extra info - Nice Shot comes in right at 10.2 – 10.3 g/cc
so- again very close to TM
