I don't think Brent caught two different people posted.
Roger (Tatelaw) shot a deer at a range that he was comfortable with the 7 mag... He would have used his rifle but was not comfortable at that long of a range with that rifle.
Luke (NMSSHOOTER) shot a doe but she was not found (yet) at the same range with the same rifle Roger shot his deer at.
Reading skills are very handy.
