    Our Price:
    $28.99
    Description:
    Verifies chamber length so you know your rifle is absolutely safe to fire. The Go gauge is used to measure the minimum allowable, safe chamber headspace. If the bolt does not close on a Go gauge, the rifle is considered unsafe to shoot. Slightly longer, the Field gauge is used to measure the absolute maximum allowable, safe chamber headspace. If the bolt closes on a No-Go gauge, the Field gauge is used for an additional check. If the bolt then closes on the Field gauge, the rifle is considered unsafe to shoot, you’ll have to have the barrel set back and rechambered. Includes a durable, plastic storage case. Mfg: Forster

    Item#:

    Our Price:
    $9.99
    Description:
    Sinclair Bump Gage Inserts are used to measure the amount of shoulder bump when setting up full length sizing dies. Our Bump Gages install in either of our comparator bodies and are machined to fit particular shoulder angles of cartridges. Rather than measuring to the datum line, these gages indicate off of the shoulder of the case to get a better, more easily assessable measurement of how much you are actually sizing your cases. We usually recommend between .001" to .002" bump for bolt action rifles and between .003" and .005" for AR15 type rifles. Also a useful tool for keeping your brass and loaded ammunition separated if you have multiple rifles chambered for the s Mfg: Sinclair International
  5. Sinclair Chamber Length Gage - Sinclair Chamber Length Gage/7 Mm
    Item#:
    749-000-784  
    Our Price:
    $5.99
    Description:
    The Sinclair Chamber Length Gauges are designed so the handloader can determine the true length of his rifle's chamber when measuring from the bolt face to the end of the chamber's neck. This measurement will tell you how much excess case length your chamber may have over published trim lengths in reloading handbooks. The Sinclair Gauges are inserted into a fired, unprimed shortened case and then chambered into your rifle. The insert pushes back into the case when it contacts the end of your chamber. You then extract the case and measure the overall length. The gauge is made of 12L14 soft steel so it will not damage your chamber. Step-by-step instructions accompany each gauge Mfg: Sinclair International

    Our Price:
    $19.99

The best way to check this critical dimension is with a Lyman case length/headspace gauge. he reloader simply inserts the case into the gauge to insure that it does not exceed the maximum or fall below the minimum allowable headspace. Caution: Any case found with excessive headspace should be destroyed immediately. Mfg: Lyman
  7. Wilson Case Gage - Case Length Headspace Gage .338 Lapua Mag
    Item#:
    749-011-860  
    Our Price:
    $26.99
    Description:
    The most important use of a cartridge case gage is for setting up 7⁄8"-14 press type full length resizing dies. A common error in reloading is to oversize your brass. Headspace of fired cases can quickly and accurately be measured using this tool and a caliper. Regular Style: This one piece gage will check overall length to indicate a need for trimming and datum to head length to assure correct headspace to prevent over sizing. Adjustable Style: For belted mags. While the belt provides support for proper headspace, the life of the case will drastically shorten unless resizing is held to a minimum at the shoulder. SPECIAL ORDER CASE GAGES ARE AVAILABLE---MEASURE CASE Mfg: L.E. Wilson, Inc.
  8. Digital Thickness Gauge
    Item#:
    749-006-095  
    Our Price:
    $59.99
    Description:
    This thickness gauge from Insize Tools is an accurate, very fast and easy to use tool for measuring neck wall thickness. You can make multiple thickness measurements around a case neck in just a few seconds to determine the neck uniformity, or easily calulate a needed neck bushing size without having a loaded round. The gauge works with a spring loaded sliding anvil so the anvil pressure is always consistent, and comparing multiple measurements will be accurate. The ball anvil for case necks or tubing can be moved down to allow the gauge to measure flat stock up to 1 inch thick. Accuracy on the digital display is 0.0005 inch, with controls for on/off, zero and inch/millimeter. Comes in a Mfg: Brownells
  9. Case Mouth And Neck Tension Gage - Case Mouth And  Neck Tension Gauge
    Item#:
    100-015-615  
    Our Price:
    $11.99
    Description:
    Measuring neck diameter with calipers is an "iffy" proposition at best. A small burr on the case mouth, a slight angle to the calipers, or even just placing too much tnsion on the calipers can give distorted readings. Improper neck tension can make preojectile insertion more difficult, or even cause a safety issue if the neck is too loose. This gage is for 224 diameter and 308/310 diameter brass. It will do cartridges such as .223 Remington, 5.56mm NATO, 7.62mm NATO, .308 Win, .30-06, 7.62x39mm, and many more. Mfg: Ballistic Tools SPECS: Steps are .218, .221 and .224 on the 22 side, .302, .305 and .310 on the 30 caliber side.

    $89.99
    Description:
    We believe the Sinclair Concentricity Gauge is the easiest to use and most accurate gauge of its kind on the market. Precision made for a lifetime of use, the Sinclair Concentricity Gauge will accept cases up to 50 BMG. The Sinclair Concentricity Gauge is used to measure runout by rotating the case or loaded round on two sets of bearings that are captured in anodized aluminum blocks. These bearing blocks are adjustable longitudinally to allow for different case lengths or varying lengths of loaded rounds. The handloader can measure sized cases on the neck, and measure loaded rounds on the neck or out on the bullet. The bearing blocks ride in a milled slot in the gauge base plate.
