A case trimmer is generally part of a reloading kit. Case trimming is the final step in the reloading process. After you put a new bullet back together, it is still not ready to load and shoot. The brass casing must fall within a precise realm of measurement. The exact length is different depending upon the exact caliber of the ammunition. The need for trimming the casing is where a case trimmer comes into play. When you fire a gun, there is an explosion. This explosion pushes the bullet out of its brass casing and down the gun’s barrel. Over time, these explosions cause the brass casing to stretch and distort. When the casing stretches out too much, it lengthens the brass to the point where it is no longer within specification. A case trimmer trims the brass casing back down to its acceptable size.
The best case trimmer is quick and precise. Case trimmers come in one of three forms.
- Handheld Case Trimmer: A handheld case trimmer is ideal for those who are new to reloading. Handheld trimmers are relatively inexpensive and easy to use. They produce quality results. There is a gauge that measures the necessary length, as well as a cutter. The cutter is what trims the brass casing down to an exact measurement.
- Bench Mounted Manual Case Trimmer: A bench mounted manual case trimmer is ideal for two scenarios. First, it is an excellent choice for anyone who needs to trim a large volume of brass. This is because these case trimmers are very fast. Second, bench mounted trimmers provide immense control over the exact length.
