************************************** *Bolt Shims* 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 isnt up tight against the breech it tends
to cause misfires and light strikes. If your getting misfires and light strikes shimming the bolt is a good way to solve it. - Jerry M.

Ruger 77/22 77/17 Bolt Shim
Installation Installing bolt shims requires fitting by hand, not measurement. Start with
the thinnest shim, (.002") and install, then check to see how your bolt closes. As long as it continues
to close normally, continue to add shims .001" at a time, stacking as necessary. When you have installed
enough shims that is begins to be hard to close, remove .001" so it closes normally or just (ever-so)
slightly tighter than normal. If you have to force or put undue stress on your bolt, you should reduce the number
of shims. Bolt Shims have in many instances cured light strikes.

I recently received a Ruger
77/22 in .22 Hornet after waiting almost 6 months for it. It gave pretty good patterns, not quite full choke,
more like modified. No matter what I did it wouldn’t do any better. In addition to terrible grouping, somewhere
along the way while shooting my bullet impacts would suddenly start marching up the target to the northeast. In one
case the string measured at least a foot and a half. It may have been more but the last two shots were off the target
board. I went online and read that quite a few people were having trouble getting the 77/22 to group and the
recommendation was shimming between the front and rear of the bolt. Your address was given so I ordered a set.
I put in a .003" shim and got some improvement but not enough to crow about. I decided simply putting in a shim
without testing wouldn’t do it. I removed the .003" shim and put in a .004" and a .002" to equal
.006". The bolt was definitely tighter! I could close it, but it didn’t feel right. I took out
those shims and put in a .005". Eureka! The bolt closed snugly. Next trip to the range got me
groups that were worthy of the Hornet! And no more marching to the northeast. Your shims work! Thanks.
Archie M. Fort Walton Beach, Fla.
the order today and am very satisfied. Actually better quality than expected. I had been searching for a very
long time for pre-made shims for the Ruger 77/22 Hornet when another member at http://rugerforum.net/ posted your site address
with high recommendations. Next time I'm in that forum I'll certainly endorse his recommendation. Thanks for a great product - Jerry in OK
Hi Lance I just wanted
to drop you a note to let you know your shims arrived and I am more than pleased with the results. I shimmed the
bolt on my Ruger 77/22 and the preliminary tests have been a reduction in group sizes approximately 25 to 30%.
Thank you so much for a quality product and the prompt shipping was a nice surprise. I will certainly be recommending your product! Norm in Saskatchewan, Canada
My son and I have several 77/22's
My 22 hornet would not shoot at all, I tried different loads, different bullets, nothing worked. My son told me about
reading on a Ruger forum about your product . I put .007" in the hornet, not only does it shoot great one
hole at 75 yards but I am also not having the base come off the case after two reloads . Now I am ordering for
friends with the same problem . - Fred H in MT
Target Sear Review I
just got back from the range today after installing a couple of upgrades to my Ruger 77/44. I purchased and installed
a Target Sear Kit and Trigger Shims from www.TriggerShims.com It made a huge difference taking the pull from about
6 lbs. to a crisp break around 1.5 pounds. It was very easy to install and there are videos on the web site listed to help.
I have another 77/44 I installed a Rifle Basix replacement trigger on a few years back.... I think the Volquartsen Target
Sear install is better at half the price. I ordered it on Sunday and got it today... Great service. Mike S. in Indiana
