Nope, that's a close shot group.
Keyhole is the description of a unstabalized bullet. Early in it's life the M16 had horrible problems with their bullets being unstabalized and keyholed bullets. A little work on the loads and a change in the barrel twist took care of it.
It has also been used to describe what happens to bullets when they enter a body. Some bullets may have good flight characteristics but will keyhole when they enter the body. The M16 bullet still does this to this day. A light full metal jacket bullet is very prone to the keyhole effect.
Here's a picture of what a keyholed bullet looks like on paper. This is a very unstable 6.5X54 MS fired out of a Steyr (M1903).
