I have a Marlin rechambered by Nonneman in 307. The Marlin will also cycle 308 brass loaded to 307 specs. My favorite load given to me by Slim is 40.0 grs of 4064 under a 170 gr Speer hot cor. This combination is deadly on our NYS whitetail. Another option is a 30 30 AI.
The 170 grain Speer bullet driven about 2,350 fps just seems to be ideal for our average size Whitetail (160lb is a big one) and our smaller pigs. The Speer bullet has good expansion, weight retention and penetration. I expect deer hit under 100 yards to drop in their tracks with a cross body shot.
At this velocity the rifles have light recoil and are easy to shoot from field positions.
The Speer bullet and IMR 4064 are a good combination in the .307 Winchester. Not the highest velocity but excellent performance on game inside 100 yards. It is still my go to load.
