Alot of the load data I've found in manuals is for the standard length AR platform. Things change when you do down to a 16" barrel... I am interested in any loads proofed through the 16" barreled M4 rifle. H322--? H335--? I plink with 55 FMJ's over 24 gr H 335 and with the 1/7 twist I've played with 75gr Hornady match over 22gr A2495 Both with Remi 7-1/2 primers, LC brass, crimped with Lee Factory Crimp die. Anyone else load for the 16" AR willing to share you loads I would appreciate it.
