My fiance started hunting with me last year and I got her a .243. She shot her first deer with it this year around 70 yards across a field with no obstructions to the flight of the bullet. She made a perfect shot, maybe an inch back and the buck dropped in its tracks. When we gotto the buck I noticed no blood on the ground around the deer and when I flipped it over there was not an exit hole. If this buck had run there wouldn't have been a blood trail to follow. I'm worried that if there was no pass through on an open shot like this what will be the result in the woods if there's some brush or something. She shoots a 100 grain Remington Core Lokt. Any recommendations for some more powerful options with the .243?
