This is for ammunition that has been precicely reloaded. Ammo case holders on the market do not take the precision aspect into concideration. If the bullet tip is jarred in any way, then your precision is lost. The case rests in the holder from its shoulder and the bullet does not touch any part of the case holder. Thus maintaining your reloaded rounds precision. This case will fit inside of a 20-round box of ammo. I will be makeing larger cases for this caliber, and developing cases for other calibers, in the future.
This was designed to fit inside a Hornady Black 5.56 20-round ammunition box. I use it to bring my developed test loads to the range. I only need 10 round to develop a load, but I make 2-10 round loads to get better numbers in the development process.
