CHAMBERS FOR THE 223 and 5

Derrick Martin Chamber - 2.442 (223 ammo - Special Loads) Bill Wylde Chamber - 2.445 (223 ammo - Special Loads) AMU - 2.500 (5.56 - Special Loads) NATO - 2.550 (5.56 - Special Loads) Chambers: that all-important point where everything starts. The good news is a longer throat doesn't seem to matter to the performance of shorter bullets. ................
