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 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.
Factory fitting of the barrel into the receiver can also leave excess clearance between the bolt and breech. Excessive headspace causes the bolt to feel loose.
Shims can also Used for Adjusting after Re-Barreling
If you are getting misfires and light strikes shimming the bolt may be a good way to solve it.

Customer IAN from New Zeland writes about his Ruger American® Rimfire Long-Range
Good Morning Lance and Tammy,
I have decided to write a small message to regarding my experiences with your shim kit. I had purchased a Ruger American .22 Long Range and to say the accuracy was poor was an understatement. Nothing I did helped much. I did the bedding, Action screw tension, the barrel crown, the trigger, one item at a time with extensive ammunition testing each time to find something it liked. My CZ’s even with ammunition they didn’t like still outshot it. Then I saw the Youtube video by Mr Revolver Guy from Day at the Range and thought ok, lets try the headspace and if that doesn’t work, I will sell it as it’s a dog. I followed the easy instructions and straight away the groups tightened and also it started accepting ammunition it had sprayed around the targets before, every group tightened. Like all 22LR it still has it’s preferences but all the groups are now touching at 50 yards. My thanks to you both, Regards Ian


Can you improve on this fine Rifle?
I think a set of TriggerShims Brand Shims can Certainly Help!!
But don't take my word for it, read this unsolicited Testimonial;

Lance,
Yet again I am a very impressed customer.
I was given a Ruger American Rimfire by my sons and wife for Father's Day 2 years ago and I just couldn't get the trigger "just right". Now, I had to keep this rifle because it was given to me as a gift - so I worked and worked on the trigger, polishing until the trigger and sear were mirrors - but still it was gritty and inconsistent.
Then, I stumbled across your kit and video and $15 and about 30 minutes later - I had the trigger I always wanted and knew the Ruger had hiding in there somewhere.
My Ruger had .015 slop / play, so I had to use two shims to get .013 and I put it together per your video instructions - and put the bolt in and closed my eyes and ..... FANTASTIC!
Gone is the grit and creep and the trigger is now consistent and I can't be happier.
Thank you for making such a great product at a fantastic price point.
I remain a loyal customer -
R.M. in PA

LANCE'S 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.
You can use our color coded numbered shims like a gauge to find the 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 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 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, 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 receive no benefit you may send your shims back for a Full Refund.

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
