Take an old pair pliers that you don't love and heat them up cherry red and let them cool slowly - annealed. Mic the 22 projectile and then choose a drill bit that is say .005" to .010" under. Put pliers in a machinist's vise and drill a hole so that it centres on the pliers jaws. I'd dimple the centre with a punch, I'd also start with a .125" bit and move my way up in two more steps. Clean up any burrs. Test on a 22 LR cartridge. You can re-harden the pliers and temper them if you plan on doing this a lot.
