I am new when it comes to nutria hunting. recently my good friend and i went to our hunting ponds in point a la hache. We brought along the trusty .22 winchester rifle, but it wasn't cutting it ! These swamp rats are huge. the two we killed were both thot through the eyes. Now i know that many people are better shots then us, but we hit all six that we saw in the head, but only managed to kill two. does anyone have any advice, or tricks that can help me out? Maybe a differnt caliber rifle...? Thanks, Jake.
