How does a Rimfire Bolt Shim work? The actual head space is in the recessed face of the bolt. Shimming between the two bolt halves ensures the bolt is up snug against the breech. If the bolt has excessive clearance at the breech it can to cause misfires and light strikes, or simply inconsistent accuracy. When a Production Rifle is assembled, a bit of extra room or excess tolerance can be left, and this slight variable can affect accuracy. When the bolt action rifle’s bolt locking surfaces become worn increases in the headspace can cause light firing pin strikes, poor ignition (misfires), looseness of the bolt, and loss of accuracy.
