How does a 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 tight against the breech. If the bolt is not up tight against the breech it tends to cause misfires and light strikes.

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. Excessive headspace causes the bolt to feel loose.
Also Used for Adjusting after Re-Barreling

If you are getting misfires and light strikes shimming the bolt is a good way to solve it.

LANCE'S TECH TIP:
Rimfire Bolt Shim Installation
~ A General Guide ~

Unlike centerfire cartridges where headspace is on the shoulder, .22 LR is rim headspaced—the dimension from the bolt face to the barrel breech face (rim seat) determines how much "play" or clearance the cartridge rim has.

Rimmed Cartridges use the thickness of the cartridge rim for head-spacing.
.22 Rimfire Cartridges Headspace on the Case Rim.
The Actual Headspace is in the Recessed Face of the Bolt.
You Must Make Sure this Recessed Bolt Face is Equal To or Deeper Than Your Rim for Safety
Generally speaking, there is extra room left in production guns between the Bolt and Breech to accommodate a wide variety of ammunition with varying rim thicknesses.
You should first measure the depth of your bolt face pocket to ensure it meets SAAMI Headspace minimum depth.
Shimming between the two bolt halves ensures the bolt is seating the cartridge up gently against the breech with your chosen brand of ammunition.
You can use our color-coded numbered shims like a gauge to find when the bolt face touches the barrel breech face, and then calculate where you want to be with your bolt headspace depth and rim thickness measurements.
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.
If possible, it may give you a better feel if you leave the extractors off some rifles while fitting shims.
Start with a 4 or 5 pack 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, stacking shims if necessary.
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. For example, if a .005" Red Shim causes the bolt handle to close harder than normal, then take it out and install a .004" Purple Shim.
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.
If the bolt closes slightly tight, it is best to back up one step, remove .001".
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 the rim thickness of your favorite cartridge.
For longest shim life, use a drop of oil or a (very small amount of) grease on your shim.
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 while maintaining proper headspace. 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 or to crush the rim. Did I explain that clearly?
Forcing the Bolt to Close will put premature wear on the bolt shims and will not increase accuracy.
If you have any questions, use a headspace gauge to check for proper headspace.
Bolt Shims have in many instances cured light strikes.
Will they help with accuracy? Don't take my word for it. Read our Customer Reviews or ask our Customers.
Simply Chambering More Consistently Yields More Consistent Results.
Your Satisfaction is Guaranteed. If you feel you receive no benefit, you may send your shims back to TriggerShims for a Full Refund.

Unsolicited Testimonial:
Just a friendly note on the bolt shims I purchased and installed. My 5 shot group went from dime size at 50 yds to everyone touching and not being able to count individual holes.
Thank You for a Great Product ~ Riley in WV

Unsolicited Testimonial:
Lance, I simply wanted to say thank you for providing Bolt Shims. My first one installed was on my Bergara B-14 22 Trainer. I won the club season matches in 2022. It's more accurate now than my winning season. After seeing an improvement, in an already accurate rifle, I've shimmed my Bergara Shooting Rimfire barreled action, two CZ 457, my 2020 Springfield, and my my 54 Annie. The Anschutz allowed for 5th place in the IR 50/50 factory class last year. I shimmed it yesterday. The common fliers were less frequent and overall consistency was improved. A noticeable improvement was seen in all the rifles.
Thanks again for offering a great product ~ Rob in NC

Republic.... I like the sound of the word. It means people can live free, talk free, go or come, buy or sell, be drunk or sober, however they choose. Some words give you a feeling. Republic is one of those words that makes me tight in the throat - the same tightness a man gets when his baby takes his first step or his first baby shaves and makes his first sound as a man. Some words can give you a feeling that makes your heart warm. Republic is one of those words. - John Wayne in the Alamo
