Hey!Hey!

kurt,
interesting those 2 bullets have the same sight setting with the same charge.
the kal bullet is quite a bit heavier, so would probably start slower.
this suggests it must have a higher b.c. than the prolate.
whether this is due to increased weight, or lower nose drag is an interesting question.
I suspect nose drag has something to do with it, as it is surprisingly the prolate that is less stable, suggesting its centre of pressure is further forward.
this mirrors my findings with similar profiles in 40 cal.
keep safe,
bruce.
