LENGTH GAUGE Reviews & Ratings

HORNADY LOCK-N-LOAD OVERALL LENGTH GAUGES

The Hornady Lock-N-Load OAL Gauge (formerly Stoney Point) is an extremely easy to use tool. It only takes a couple of minutes to find the overall length for a particular bullet. The tool is threaded on one end to accept specially modified cartridge cases. Once threaded onto the tool, a bullet is inserted into the cartridge. The tool is then inserted into the chamber of your rifle. The push rod on the tool is used to push the bullet up against the rifling. The rod is then locked in place and the tool can be removed from the rifle. You then measure across the base of the cartridge and the top of the bullet with your dial calipers (use of a bullet comparator at this time is highly recommended) to obtain the OAL. If you want to check another type of bullet, insert the new bullet into the tool and repeat steps.

There are two different models of OAL Gauge tools available. Straight is designed specifically for bolt-action rifles and single shot rifles. The Curved model is designed for autoloaders and lever actions. Both models utilize the same modified cases. Either tool will work on the AR-15 type rifles. This tool is excellent for periodically checking the throat erosion of a rifle barrel. Great for checking out used rifles. There are over 60 different modified cases available to use with this tool.

Handy tool

WISH I HAD THIS 30 YEARS AGO! I used to determine seating depth with using a carbide lamp to blacken bullets with soot and carefully chamber the round to get a "touching the rifling" O.A.L. This tool is simple and it works. Although it does take a few tries to get the "feel" of when the bullet just touches..

HORNADY Lock-N-Load OAL Gauge

I use it for competitive shooting. Easy to use. The inconvenience is the necessity for a modified case.

Great tool

Okay I got this tool some time ago, and did not think much of it until I did some reloading of new stuff. I got some new bullets that I don't normally use they are longer and much better brand. I set up the stuff and went to work. Put the finished round in the gun and stuck the bullet in the barrel. With this tool I got the new overall length and I'm back in business.
