Precision deluxe case cutting jig with high impact plastic guard for 300 Blackout and others with similar case length. Affordable and precision products is what our company is known for and this is one of our many quality products with a price that is unbeatable. For a .223/5.56 cartridge to be accurately cut off and have the neck perfectly plum to the cartridge bottom, precise alignment is required. This can only be achieved with our design because the fixture is cut to fit the actual taper of the cartridge. Additionally, our case length will be exact each and every time you cut. Since precise cuts require a tapered bed for cartridge alignment the case cannot be pushed forward after its cut. You just lift the back end of the cut case up and toss it in a can and grab another, place it into the fixture, apply a little backward force so the case bottom rests on the stop for precise case length registration. Clear guard is placed so it does not interfere with your hand, and it can be easily removed. 100% Made in the USA
