Does anyone have any experience with the Hornady 139 grain SST on deer? I usually use the Hornady Lite Mag. 139 grain SP bullet but this year, I have been unable to find any of the 139 SP ammo, so I bought a box of Hornady Lite Mag. 139 grain SST's. I was able to get 3/4" groups at 100 yards with them. If you have used these bullets on deer, how did they perform?
