One of my hunting buddies uses a 10" 30/30 T/C barrel, and he started using the Leverevolution ammo last year. It has worked very well on deer, hogs, and turkey. With groups just over 0.5" @ 100 yds, he has decided to buy the Hornady ammo instead of reload for the barrel. The 3 deer, 12 hogs, and 2 turkeys only needed one shot with the FTX bullets.
