Thanks Darryl, great info. This makes a lot more sense than the info Barnes CS sent.

Sometime in the next couple months I'll try a reduced H4895 load and fire though some water-filled milk jugs. Hodgdon's reduced load guidance for H4895 is low as 70% of max load. We don't have actual max load data, but if I assume 2 grains below max 30-30 170gr as max for a 190, that puts max at about 28.0, so I'm thinking I'll try something like a 24 grain reduced H4895 load; that ought to get the velocity down around 1650 fps (I actually had 1723fps with 25.5 grains H4895 with the Barnes 190 3030). Should be a good test to see if the bullet expands at that lower velocity (which I bet it will) and a good proxy for what the bullet would do at 100yards with hunting loads.
