Bergara B14-R Bolt Shims
Bergara B-14R Rimfire
~NEW~ Bergara B 14R Rimfire Bolt Shims
The Bergara B14-R's two-piece bolt features a spacer/shim that sets the rifle's headspace. TriggerShims offers a spacer kit that will allow headspace adjustment in 0.001 increments.
.001" shims are too thin/delicate to be practical. In my opinion, proper clearance is .001" and if a .002" shim is too tight, no shim is needed.
These are the Original TriggerShims Brand B-14 R Bolt Shims

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.
Proper Adjustment of the Bolt / Breech with Our Shims may Increase Accuracy

TECH TIP: Rimfire Bolt Shim Installation
~ A General Guide ~
Rimmed Cartridges use the thickness of the cartridge rim for head-spacing
.22 Rimfires Headspace on the Case Rim, and the actual head space is in the recessed face of the bolt.
Shimming between the two bolt halves ensures the bolt is up gently tight against the breech.
I cannot tell you which shim best works with your rifle, you decide that yourself by fitting and feel and by shooting.
Installing Bolt Shims requires fitting by hand, and checking with the Bolt installed in the Rifle, and Locked Down - you do not measure with the Bolt out of the Rifle.
To establish the Bolt/Breech fit, shims are installed and fitted on an empty chamber. Start with a 4 or 5 Pak of shims, install the .0015" or .002" thinnest shim and see how your bolt closes, if it seems to close as normal, then continue to install each thicker shim until the bolt starts to close harder than normal. At the point where your bolt begins to close hard, that was the amount of slack that was in your bolt, measured by whatever shim or shims combined were needed to bring the bolt up tight to the breech. Now it is best to remove that shim, and step back one number, example would be if a .005" Red shim causes the bolt handle to close harder than normal, then take it out and install a .004" Purple.
If you have to force or put undue stress on your bolt to close it, you should reduce the number of shims. You will generally only use 1 of the 4 or 5 shims in the package, but you can stack shims together if needed. When you have the correct shim installed, your bolt should close normally or just (ever-so) slightly tighter than normal. Put a very small drop of oil on the shim. Now you can go to the range and with the barrel pointed in a safe direction, once again check fit with your favorite ammo.
Due to variations in rim thickness, you may have to reduce the thickness of shims, remember you have already removed all the excess headspace from the bolt/breech, so now the only thing to do is remove thickness (shims) if / as needed to get to your sweet spot or required headspace.
For Longest Shim Life, once you have have correctly fitted your shims Top Canadian Shooter Dan Walker from Inrange Rimfire recommends using a heavy grease.
If you have to force or put undue stress on your bolt to close it, you should reduce the number of shims. A minimum of clearance should be maintained, do not put undue stress on the bolt by shimming too tightly as it is unnecessary!
At no time do you want to force the bolt to close, did I explain that clearly?
Bolt Shims have in many instances cured light strikes. Will they help with Accuracy? Don't take my word for it, Read our the Customer Reviews or ask our Customers
Simply Chambering More Consistently, Yields More Consistent Results.
Your Satisfaction is Guaranteed, if you feel you got no benefit, you may send your shims back for a Full Refund.
