Loading so many different calibers for competition this makes it easy to do a quick check and get the trimmer set, so much faster than using a caliper on every round.

Easy to use case measure tool. Has spots for all (well 70) of the most popular rifle and pistol calibers. This, or something similar, is a must have to safely reload ammo. Amazon had the best price of $23.99 I found. Some sites were charging close to double this price. Once again amazon is the best option.

While it isn't as good of a solution as those individual gauges this is a great and handy general tool. You can lay it flat and check several cases very quickly.

WOW! This is a great tool for checking the length of your casings before reloading. Simply place your empty casing along the straight lower level, slide it towards the proper caliber, and it's a simple GO-NO GO. If it fits, the length is ready for reloading. If it does not fit, the casing will need to be trimmed. This is far faster than using a caliper. My average time per casing was in the range of one checked every 3 to 4 seconds! It is made of a reasonably heavy (ie, substantial) metal and should last for years. One caveat is that the photo shows a white metal gauge with black lettering, but mine came with a black metal and white letters. I think the black on white, as shown in the photo, would be easier on aging eyes. Not sure why they (Lyman) reversed the color scheme.
