RE: Ballistic or
What have been the results of the deer you have killed with the 180gr Accubonds??? I can't imagine a deer walking very far after having one of those missles hitting it, I kill them all the time with 85 and 100gr bullets out of a .243...
The Accubonds are a "harder" bullet than the original ballistic tips which came out a few years ago, my cousin has had good success with his .270 WSM and the 140gr Accubonds loaded by Federal...
As far as the softer balistic tips, one of my brothers has killed a few dozen deer with his 7mm-08 and ballistic tips...I think in a 7mm-08 or a .308 where max velocity runs about 2800 fps the ballistic tips shine...
If you want to try the 150 for flatter trajectory then they should be fine, it's just beyond me why a 180gr .30 caliber bullet won't do all that needs to be done to a whitetail...
