I have read several reports of deer being shot with .223 and big game bullets leaving little to no blood trail. After my seven year old killed one on Saturday with a 50 grain TTSX and deer left no blood trail it got me to thinking. I think he will hunt with the 223 at least one more year and then I have a younger son that will use it also so I am thinking I will need to change bullets and/or caliber to see blood trails.

Do the heavier (65+ grain) bullets leave a better blood trail on average from the 223?

Do .224 bullets work better with more speed say from a 22-250, 220 swift, etc. ?

Or all they all about the same?
