I second that, I used the same .303 in super X 180 gr. power-point last fall on Western Quebec deer and it punched an entry point the size of a toony in the rib cage. Heck if you NEED a caliber greater thanSignGuy said:well i havent had the privilage to hunt in ont yet (soon i hope) but i have hunted in N.S and i use .303 british winchester super x 180 grain and have had fairly good luck with them they seem to drop em effecintly as well maintain little to no spoilage as far as bullet wound goes but i agree with everyone that the .300 weatherby is way to much gun for whitetail even for those ones that hang around the nuculer powerplant
30-30 to drop your deer, you need to spend more time on the range...
