What you are looking for is a 35 Remington load, and a bullet designed for that cartridge would be what is needed. However, if you are looking for a 200 yard load, probably a starting load for the Whelen would be better. Whether that is reduced enough is for you to decide. My experience with the 35 Remington was good, but most deer I shot with it were under 20 yards, and the few beyond that were at 40 yards or less, hunting creek bottoms and thickets. It would likely kill at 200, but that’s out there for the load, in my opinion.
