I’ve never killed a deer with a 30/30 round before, I’d like to get on the board with one though. What grain bullet is best for deer 🦌 hunting with one? I’ve shot 2 deer with 150 gr., got blood on both but didn’t knock the deer down, nor recover the deer. I know I need to concentrate on my shot placement, but I’m wondering if I should go with 170 gr. Bullets? Thanks in advance, Robinhedd
