Hi does anyone have the chamber diagram for Remingtons new 30AR? i have heard it is a shortened 284 case but the performance seems poor a 125gr projectile at 2250fps a 30BR will do that but i am wondering how it would go necked to 6mm so if anyone has a fired case or reamer print and the case capacity i would realy appreciate it.
