Nuovo Record hub spoke holes and DT spokes

I have laced up a number of Nuovo Record and Tipo hubs but I usually use 15g (1.8mm) spokes. Recently I tried lacing up a used Nuovo Record low flange rear hub with 14g (2.0mm)-15g(1.8mm)-14g butted DT Competition spokes. The problem is the spoke holes, while measuring 2.3mm are drilled flush with the flange surface without any rounding or countersinking. DT spokes are cone shaped behind the head as it reduces from the diameter of the head to the diameter of the spoke. The result is the back of the spoke head would not lay flat against the flange and the spoke would bow out while being laced. This wasn't an issue with 15g spokes. I ended up drilling a slight countersink under the spoke heads which solved the problem. My question is, is this normal?
Is it just an issue with DT spokes?

I've read that DT changed the length of their "elbow" at some point, making it longer, and wondering if that could contribute to the problem. Your 15 ga spokes may have been from older production run. ???

The last wheelset I built had the same concerns. I still laced the wheel, set the spoke heads with a small punch, then pushed the spoked elbow to reduce the radius of the bend. I then trued and tensioned the spokes as I normaly do. The wheels came out perfect.

The countersinking of the flange is not meant to allow the spoke head to get in.

It is meant to allow a smoth transition of the bent side of the spoke.
The spoke is to be inserted in the opposite direction
