Default 03 butt plate screw hole size

It seems that the large butt plate screw hole in my stock is undersized. Does anyone off hand know the proper size of the hole before I screw it up?

it needs to be tapped,
I made my own tap for it, I cut a buggered screw, and welded a T handle on it,
if you dont tap it first, you will stick a screw in it.
even with a tap.
some soap on the threads help

Manufacturing prints shown on pg 258 of the Colvin publication indicate a .25" pilot followed by a 7 TPI tap that has a major diameter of .317". Soap helps a lot as Chuck said.

That's some initiative.

Interesting but useless fact... Springfield Armory butt plate screws are the same for trapdoors, Krags, '03s and Garands. The screw making machines just last forever, and SA attempted to save money by using as many "old" parts as they could on "new" rifle models.

Maybe the top screw on the 03 and Garand are the same, but definitely not the bottom.

I got the screw in, but using a technique that may make some with more advanced skills cringe.

if you are using reproduction screws its hit and miss, Screws that Sacro sells are over sized on the big screw and under sized on the small screw,
both screws are the same from the Krag all the way through to the 1903A3.
1917 screws however are not, and have a different head and are longer and have a deep shoulder,
make sure your installing the correct {original screw} and work it in and then back out, going deeper each time.
