Rem 40X Bolt Shim ~ .570" X .690"

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.

Remington 40X Close-up

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.

When searching for Accuracy, ~or~ If you are getting misfires and light strikes shimming the bolt is a good way to solve it.

Remington Extractor 870 / 1100

Volquartsen VCREM

Volquartsen VCREN

The Exact Edge Extractor is manufactured through an EDM process (not an inferior MIM process) to produce exacting tolerances. The new extractor will not lose its edge under impact like extractors made from stamped steel that will have their edges roll over and actually cause extraction problems after a short period of use.

Our extractor features a very precise hook point. It is hardened to a Rc 58-60 to withstand years of use and still maintain its edge. We are able to hold the tolerances to +/-0.0001" by utilizing the EDM manufacturing process.  Made of A2 tool steel.  Replaces Remington part #16176 and fits 870, 12, 20 and 1100, 12, 20

Wolf High-Performance Target Loads

Click to go to Brownells Wolff .22 LR Ammo

This is the ammo I use and recommend.
Five round groups in one ragged hole are possible with this ammo at 50 yards benchrest, as I have done it.
It may not be as consistent as the $15 a box stuff, but it fits my pocketbook when I want to make holes in paper!
Wolf 22 LR target ammunition is loaded with VihtaVuori powder prized by centerfire benchrest shooters for its consistent burn rates. The high-quality brass is formed using a proprietary manufacturing technique that maintains outstanding round-to-round consistency to help deliver consistent pressures and superb accuracy.
This ammo is sold and shipped through Brownell's - click the picture to go to Brownell's Wolff Ammo Page.
