## Overview

The Hornady C1000 Lock-N-Load OAL Length Gauge is a precision tool designed to regulate bullet seating depth and optimize the 'jump' to rifling, crucial for improving shooting accuracy. Featuring a durable aluminum housing and compatibility with bolt-action and single-shot firearms, it enables shooters to measure overall cartridge length with thousandth-inch precision. Portable and easy to use, this gauge is a must-have for reloaders seeking to push their accuracy to the next level.

## Description

One of the best kept secrets in accurate reloading is precise bullet seating depth. Regulating seating depth and the resulting "jump" to the rifling is widely regarded as fundamental to improved accuracy. A few thousandths of an inch change between the bullet and the rifling can make the difference between average accuracy and real tack-driver performance. For all bolt-action and single-shot firearms, or any firearm with straight-line access to the chamber.

Review: Accuracy at the next level... - Seating depth is a critical measurement in precision reloading and this tool makes it possible to accurately measure as each bullet type touches the rifling lands providing a true overall cartridge length measurement. It also enables precise measurements to determine and monitor barrel throat wear as the barrel ages with use. I have found that it takes some practice to seat the bullet against the lands accurately so consistent measurements to a thousands of an inch are achieved. I take the average of three groups of 10 measurements to determine the OAL measurement. I use this tool in conjunction with a bore scope so as I push the bullet into the throat, I can monitor exactly when the bullet touches the lands but I have discovered that after the bullet touches the lands, it’s not possible to push it forward any further with normal hand pressure, so the bore scope is not actually beneficial. I wanted to take my shooting to the next level of accuracy so I bought the Hornady comparator tools (base, anvil & inserts) to measure from the case datum line & bullet ogive. These tools are well made, easy to use and very accurate. Precision shooting is all about eliminating variables and these tools do just that by providing a way to measure more accurately. In the past, tools of this nature were very expensive but Hornady has found a way to provide these tools at a great price so more shooters can enjoy the benefits. If you want to play at the next level, these tools are essential.

## Questions & Answers

**Q: What is the thread size on the end. I want to use brass fired in my chamber to make my own modified brass**
A: The tap is UNS 5/16 - 36.  I bought the tap and tried several times.  Then I sent in two brass cases (fired in my chamber) of each caliber to Hornady and they made ones that worked.  Unless you are a skilled machinist with a lathe or tools to drill the case out perfectly straight, you are wasting your money on a tap.  I  did not have the proper tools and failed.  Hornady charges $35 a case and was quick to get them back to me.

**Q: How do you know the bullet is in the same position in the case after you pull it out that it was in while chambered?**
A: Once you are comfortable the ogive is making contact with the lands, tighten the thumbscrew on the shaft. The bullet seldom comes out with the case, so locking the shaft allows you to place the bullet back in the case to get your measurement.  I hope this helps.

**Q: will this work on a Marlin Guide Gun?**
A: You have to be able to take the bolt out and get straight access to the chamber so I don't believe it would work on lever guns. However, not sure on your model of lever, if you can get the bolt out then it would work.

**Q: Can I tap a piece of brass I have with the hornady “stuck vase removal tap”?   Will the tap allow case to attach to this tool?**
A: I don't have a Hornady stuck case removal tool so I have no idea if the diameter and pitch of the tap is compatible with the lock and load tool threads. But I wanted a couple of different caliber tapped cases for my lock and load and took those caliber brass and the tool to a local machine shop and they made perfectly compatible cases fr me cheaply.
