I've posted this on another site but want to voice you chaps out.

I'm wanting to load some 87gr SP Hornady Flat Base. The data on the Hodgdon website gives the 80gr at 38-41.2, the 85 at 40-43 and 90 at 38-40.5

How come the 80 and the 90 are less than the 85? Obviously the 90 should be slightly less but these figures are more significant. Anyone got the data for these?

Cheers
