What range do you intend to hunt? Bullet impact speed makes a huge difference as to how they perform.
Within 100 yards, more likely 50yards and less.
1:10 Twist
1:10 is good enough twist for what ever you can buy commercially.
Hornady SST's shoot nice. My 30-06 doesn't twist that tight so I keep mine at 165. I say push as heavy a bullet through it will group with. I know you said you are gonna be hand loading so you can really do some experimenting.
How would the TTSX work on Hogs? I'm leaning towards the 180gr Accubond because it will be the one and only load I'll need to hunt Hog, Deer, Elk, Moose, ect... (given that I can produce a sub moa load with it)
I wonder if 168gr TTSX would be too much for a WT
I have used the 168 gr Barnes for a long time and it will do fine on deer or hogs.
