That is a 1.20" shank blank vs a 1.135" tikka prefit, so maybe you are seeing the 0.0325" difference?

Your barrel is a Tikka prefit. His barrel isn't. If you zoom into the photo, I can see just a touch of shank diameter thats bigger than the Tikka nose, so he's using a proof blank that wasn't original setup for Tikka tennon OD. Its either 1.200 or it was turned down a touch. I could be totally wrong, but thats what I'm seeing in the pictures.

Gotcha! Thank you guys for the clarification

Thanks all, looks like I'm going with the medium.

Sportsmatch TO84 "Medium" are still pretty low, I think the HT073 High are closer to UM Medium.
