szihn, sorry I didn't see this when you originally posted back in July.
Of the 3 deer I have taken with the 9.3x57, all were with the PPU 285 grain rnsp at 2100 fps mv.
Closest was 35 yds farthest was 123 yds. 2 were quartering front and 1 was broadside. No bullet was recovered as all were complete pass throughs.
Expansion was evident but not violent nor excessive. Exit wounds were about 1/2 dollar size on all 3. None dropped at the shot but none went more than 25 yds.
I did some expansion tests with water jugs. All bullets recovered expanded uniformly to around 1/2" diameter to the 1st cannelure and retained weight averaged 90%.
Penetration was around 40".
