I would not be reaming holes in any guitar to get $4.50 pins to fit.
I've used those exact same bone pins myself.
They are not hard to thin down - I used a small flat file , slowly , bit by bit, rotate the pin, check for fit.
Worked beautifully.
Here's the finished swap I did from plastic to bone on my EJ-200
If the new pins keep pulling up when you bring the strings up to tension look at extending the groove in the pin a little more - like the pin pictured on the left below
