I was hoping to get it shooting through the same hole at 100m but I doubt it could do that no matter how hard someone, that can actually shoot, tried.

Try and slide a business card under the barrel all the way along to the receiver ring.

I have come across 3 Brno 601s that had high spots on the inletting for the barrel channel. 5 minutes with some sand paper would fix that problem

Would double check it first, some of the older rifles were stocked with a deliberate bump to put upwards pressure on the barrel.

Have seen this myself on an old Sako and due to the location and size of the bump I suspect they used a 'one size fits all' approach to barrel harmonics, might have actually worked with a particular factory loading which the rifle was sold with at the time.

Lee Enfields were mostly stocked with upward pressure on the barrel and they seem to shoot OK...ish...

Yep, my old Sako Forester when new had a sharpish ridge of wood under the barrel in the fore end. I glass bedded the action and free floated the barrel.

Did that improve it noticeably?

They were designed that way , the pressure under the barrel at the fore stock is to make up for the poor bedding of the action . Free floating the barrel and bedding the action can show better results? , but there is no guarantee it will shoot better than as it is now .
