The .20 Practical is an ideal 20-caliber solution for AR15 platforms. The 20 Practical feeds and functions 100% reliably with standard AR15 magazines. No mechanical mods are required to your AR, other than a barrel change. You can start with .223 Rem brass, and just size down the necks with a neck-bushing die. It works best if you bring the necks down in two stages using two different bushing sizes. For example, Winchester 223 Remington brass has a new case neck diameter of .244" so using a .236" or .237" bushing first and a .229" or .230" bushing in the 2nd sizing. Another option would be to use 17 Remington brass and run the brass through a 20 practical full length die.
