Is this catcher interference?

Over 40 men's league game. R1, Defense tries to execute a pitchout. Not so good catcher comes out of his stance way early and receives the ball at least even with the plate getting his momentum to throw to second. I called this interference as the batter had no opportunity to hit pitch (6.08(c)). I had a few words with Def HC but they lived with the call.

I realize it was a pitchout and the batter probably could not have hit the ball but where do you draw the line? If this is not interference what would stop the catcher from going half way to the mound on a pitchout and having an easy shot at R1?

Just wondering if I was being an OOO.
