personally I can't imagine using anything less than 200s in the 300H&H, with the BCs of modern bullets, the 200 has such great range... the 220s don't enjoy that same BC as a rule, and there does seem to be a measurable and non-linear drop at 220 from a velocity standpoint.

to me 300 mags should all use 200s and the 30-06 needs a 180... to really extract the maximum potential from them...

just my opinion though.

I should have our -06 back in my hands tomorrow or wednesday... I should have it at the range by thursday... and can start compiling data at that point.
