Anyone know the BC's for:
1. the 7.62x25mm suprlus 86gr round nose (@1700 fps, if it matters),
2. the Garrett Cartridge 45-70 Hammerheads, both the 420gr and the 540gr @ 1550 fps?
and
3. the 20ga Winchester Partition Gold slug?

I can't find these ANYWHERE, nor can I find a velocity curve to use an estimator. I don't (yet) reload, sohave no manuals if the info would be in there.

Thanks for your help in advance!
