I have killed nearly 2 dozen deer and pronghorn with plain jane cup and core bullets - they work.
6.5 Grendel, 6.5 Roberts, 6.5x47 Lapua, 260, 6.5x55, 6.5-06 and 264 WM. 120 Bal Tip, 120 Speer, 120 Rem, 120 Sierra Pro Hunter, 129 Interlock, 139 PMC, 140 Rem(pre Core-Lokt) - they all worked. Don't sweat the bullet - put it where it needs to go. I usually do lung shots and they may take a step or 2. The Grendel was a neck shot with a 120 Bal Tip
Any of those bullets stand out as having consistent exits from the mid 6.5s. That’s what I’m really looking for without going to the monos.
Thanks.
