Safari, if I read your previous post correctly, the 9 gram bullet weight seems awfully light for the 8mm, doesn't it? That translates to around 139 grains, much lower than the 185-220 grain standard for the 8mm bore. 139 grains is light even for the 7mm.

Sectional density would have to be in the low, low .2's or less. Can you confirm that?
