308 with 150gr works marginally. Even with a bonded bullet - like fed fusion - the penetration and mushrooming is not the best past 200m. And don't tell me that one will not shoot a bull if they see it at 300m.
Shot placement is - of course - more important than anything. But it is not rare that you have to penetrate the front shoulder on a quartering bull. Even the back leg.... and the 150 will likely not do it.
The ones I recovered were barely expanded past diameter and stuck in the meat with hardly any damage around. As they say: you could eat up to the hole.
Using 180gr is much better, even with the so-called "non-premium" bullets.
If using Ballistic Tips, SSTs so the sorts, then only broadside shots are to be taken to reliably get a good kill.
As far as the 155 Scenars recommended above.... I'd leave those for "snipers" that so not want to waste good eye lid meat.
