All copper TUI ammo is very well made. It should be very accurate.
After that, the whole TUI concept is just plain stupid. Tumbling bullets worked well enough in Vietnam, because when the bullets tumbled, they fragmented. TUI bullets remain 99-100% intact. You have no fragmentation benefit. There is no expansion benefit.
The problem is that tumbling doesn't do a lot of damage.
Even by their own video, assuming that is a standard 16" gel block, it takes more than 9" of travel before the first tumble. On a lot of animals, that will have the bullet through most of the organs without tumbling.
I have hunted with these and found that I was more prone to lose hogs with them.
