How do you know they were perfect shots if you didn't recover the deer? Maybe try the Powerbelt Hollow Points. That's what I shoot although there may be better options out there. I've only shot the aero tips once and that's only because I bought them by mistake thinking they were hollow points. I shot them at a target.
I use the 295 grain Powerbelt hollow points

I shot a 8 point buck last year during black powder hunting season. I shot him from around 130 yards or so. He ran maybe 10-15 yards and fell. It was a great shot and the Powerbelt expanded pretty well. It wasn't a pass through though. You could feel it pushing against the skin of the deer on the other side but it didn't come out. That's the only experience I have with hunting with them but I'd say it was an okay experience. I will say I didn't find a blood trail I just saw the deer laying there.

I have another friend that said he is having trouble finding blood trails for deer he has shot with his BP rifle. He said he's found a couple deer but no blood and some he thought he hit perfectly and no blood or deer. He also shoots powerbelts so I don't know if it's just how the deer is hit or if it's this bullet.
