Sawfish X2. 240 Rem. HPs are nice & soft and do a lot of damage to deer. About anything works in deer, but the ones I've had very poor luck with (less damage, more deer movement) are 240 XTPs, 240 Sierra JHCs, Norma 240 HP steel jacket, most SP bullets. Leads work OK if you get both shoulder blades. Not so good with only one.
I've killed deer with all the above bullets, but the later bunch
allowed more deer movement than the first.
