The federal Powershok (bluestuff) certainly worked well for me on sika plus it was very accurate and as inexpensive as ammo gets.
I've loaded two bullets for deer:
The 150 grain Hornday Spire Point which are relatively inexpensive and give great accuracy. My load with these ended up giving 3000fps. These bullets worked well for me in that every deer I shot with them died. I did shoot one sika calf at maybe 60 - 70 yards that suffered considerable meat damage and I lost the whole front end of it plus it still ran 70 yards. I always got an exit with them but chest shot sika always ran.
The 150 grain Nosler Partition. I've never managed to get these to shoot as accurately as the Spire Points but they are the only bullet that I've found sometimes put chest shot sika straight down. I've had good expansion even on neck shot deer, at least judging by the damage. My take on them is that the front half is relatively soft and so expands well though I've never shot anything quite as small as a roe with them. I have recovered one Partition, it was from a high angle head shot on a sika stag and traveled down his neck, the recovered bullet looked like a magazine advert for bullet performance. I'm currently shooting the Partitions at around 2700fps as my main deer load and would like to tidy up the groups a little bit but my view is they perform a little better than the Spire Points on sika, even on smaller calves which can't be a lot bigger than a roe. Meat damage with the Partitions has always been as good as can be expected based on the shot placement.
