Obviously not. But the deer wasn't at 25 yards, and I wasn't using premium bullets. barely more than 50% weight retention seems pretty poor for a premium bullet to me. Does it not seem low to you?
edit - after doing a bit of digging, I have concluded this is probably quite typical of the Accubond. One test done by Rifle Shooter Mag (
http://www.rifleshootermag.com/ammo/ballistics-test-best-300-win-mag-loads-market/) tested a bunch of 30cal 180 grain bullets at 50 and 400 yards into gel, and the Accubond was horrible compared to every other manufacturer's premium bullets for weight retention. Expansion wasn't all that amazing either, but penetration was slightly above average. It performed almost identically to the partition in fact, with these two bullets being the clear losers in the test.
Other anecdotal evidence from the interwebs seems to say 60-70% weight retention is typical, so just over 50% if it took out some bone seems like it peformed as expected.
Long story short, I don't think I'll be buying the accubonds any time soon, I'll stick with the partitions or go with a different manufacturer all together next time I buy some pills.
