Barrel marking

I came across an M1 recently that had an oversize "T" stamped on the barrel near the drawing number. What does this mean?

"T" means the barrel was "targeted"

Thank You. Now for the obvious. What does targeted refer to?

It was "sighted in" at the armory.

common marking, nothing unusual
