Wouldn't any flavor of 338 bullet from any 338 cal chambered rifle terminate deer pretty easy? Even the old and milder one like 33 Win, 338 Federal, and 338 Marlin xpress are no weak sisters. Move on up the ladder into 338-06, 338RCM, 338 win and its pretty serious territory. Really how could anything fired from a 338 not be really effective on little deer?
