I have a 94 307. I use the Hornady 170 gr flat nose meant for the 30-30. My last deer was a spine shot just behind the front shoulder. Smashed the spine and exited, seavering the artery. Deer dropped in its tracks. I treat the 307 as a beefed up 30-30. Basically more power and more reach. Easy to reload for. I was really surprised with its accuracy, consistently under 2 inches from the bench at 100. Took me awhile to find one but now I haven’t any intentions of selling it.
I’ve seen people claim you can use 308 Win ammo in it, but not sure I would try.
