Awesome product
Now this is something I should have had a long time ago. It is nice to see the variations of bullets and to have a very accurate bullet depth settling. Wel worth the money.

Works perfectly!
Use this as a great, accurate way to ensure you are getting a consistent overall cartridge length or you reloads. Since it measures against a certain point on the ogive, you don't have to worry about inconsistent trim lengths of your brass. I got the curve version to use with M1 Garands, Trapdoors, and some rifles that would not accept the straight version. The curved version will work on almost anything, including bolt action rifles.

Great for increasing your accuracy from almost any rifle
When accuracy is your goal then you really need the overall length gauge. I shoot a Springfield M1A Super Match and although this rifle is capable of amazing groups with the use of this tool and using the information that I gathered by checking this rifle I was able to see my groups shrink by over 1/4"at 100 yards I now see three round groups that are touching one another and at 500 yards by over 2" by properly sizing my rounds to the rifle. This may not sound like much but in a competition it can mean quite a few more X ring shots. In hunting it can mean the difference in a wounded animal and a clean one shot kill. I highly recommend using the Hornady Lock N Load Overall Length Gauge if you reload. By the way I now use this tool with my hunting rifles and have seen my groups decrease in size with these weapons too.

Make Sure Chamber and Throat is Clean
Special modified cases are a little pricey but you can make your own with correct drill and tap. A lathe or milling machine would be helpful but not required. But it is a useful tool even if you have to buy the cases. The measurements will not be consistent if the chamber and throat are not clean.

Excellent tool
Well pleased with the tool. Was disappointed with Amazon shipping as the package was severely damaged. There was a slight bend but I straightened it out and it works great now.
