I recently had a brief email exchange with a Sierra technician about the suitability of the SGK .224 65 grain bullet for hunting Whitetail Deer. The feedback was essentially that they were initially manufactured for an Australian company for use on Kangaroos. Afterwards this bullet was made available to the public in 2004. He noted that the SGK 65 grain is the toughest .224 bullet in the Sierra lineup.

Also offered the sound advice to first test the bullet on heart/lung shots and go from there.

We have a lot of good bullet options.
