RE: Slug guns vs. Rifle for deer
The 6mm or slug gun are both adequate for the job. In fact the 6mm vs. a standard sabot slug have very similar energy up to 100 yds. My vote is for the shotgun but with a premium bullet like Federal's Barnes Expander, Winchester Partition Gold, or Remington Ultra Core Lokt. FYI the Partition Gold kicks like a mule. I just switched to the Barnes Expander. Good luck.
