Either cartridge will work wonderfully for you use. My own preference is the .35 Remington, and IME the 200 CoreLokt will exit on broadside shots. The factory ammo is outstanding and has proven itself for nearly 100 years. I use mine in a 14" T/C Contender, loading the 200 CoreLokts to 2000 fps, or a bit faster than most factory ammo is from a rifle. If you handload then the 180 Speer is great too, and I've used the 150 CoreLokt handloaded as well, but in a factory load stick with the 200s...you won't be disappointed.
