My first pick would be a 35 Whelen second would be a 338 win mag. The Whelen has a max point blank range of 250 yards with a 250 grain partition.If you like even heavier stuff the 280 grain A-Frame is also a great performer. Its an extremely efficient cartridge and the terminal performance is amazing from the smallish 06 based case. Below is an idea of the Whelen's performance capabilities.
