I have just used Berger VLD Hunting 168 gr BTHP bullets for my grandsons Bull elk hunt. Some would say that 168 gr is too samll for a big bull of say 1000# but my 12 yr old grandson droped teh 6X6 bull with only 1 shot!
Berger bullets are superior and I highly recomend them!
The bullet went thru 1 rib, 1 lung and completely blew the heart up!
The least blood shot meat I've ever experienced and the bullet never made it to the other side of the chest cavity.
I think more than a 150 gr bullet for deer is a bit too much but that's just my 2 cents.
