There's no secret.

however you should use the correct drill bit for the size of each different
Rawl plug and try not to wobble the drill whilst going into the wall, if the
hole becomes larger than the rawl plug then fill it with polyfilla and push
the Rawl plug in and wait for the PF to harden before screwing a screw in.

the hole size needs to so tight that you have to use small hammer to tap the
Rawl plug home. :-)
