I use the RCBS .223/5.56 AR series 2 die set, comes in a black box. I also use the Lee case trimmer and a RCBS deburring/chamfer tool. I load Nosler Varmageddon 55 grain metallic tip bullets with CCI41 primers. I fire this round out of my RRA ar-15 16" barrel 1:9 twist. I average about a .800" group or less @ 100yds. Im currently trying to tighten that group down to .500" with a new powder.
Lock and load, the zombies (democrats) are coming (to take your guns)!
