Brief background first...
I'm from the communist territory of NY originally and moved to Louisiana
Discovered I could easily buy firearms
Bought firearms
Started shooting USPSA about 5 years ago
I let my pistol primer stash get low and hit the rifle primer lottery a few times....
Present time....ran across a 20" Monster barrel a few weeks back and had a lonely Aero M4E1 Enhanced receiver set laying around so everyone here knows what had to be done. I was interested in the cartridge from launch but wanted to be sure it wasn't another Valkyrie first. I'm fairly certain it's here to stay and it's the real deal. I never shot past 100yds before nevermind zero a scope. I tend to research stuff to death and overanalyze everything...I don't know, it's subconscious, but helps me sometimes.
I'll get some pics when I get a chance but it's nothing spectacular currently, still waiting on some backordered items still in a production run. My entry rig to PRS/NRL type events before dropping big coin on a chassis. I did a rough sight in and tracking test at 50yds and took her to 100yds. Had a rough time with first extraction problems then feeding issues. Big dummy forgot to open my SA adjustable block....at all! LOL Still think its not lined up right and have it too far back from muzzle to the shoulder. I'm new to the AR platform but have built a few and nailed it in the past. Short Blackouts with pistol gas, maybe the ports are bigger and less fussy? I'll have to feeler gauge it like I should have.
Anyways, after a hasty, and I mean hasty 1.5MOA zero at 100 I dialed in for the 600 yd steel. This is what amazed me about the 6ARC....18mph gusty/switching wind 90 degrees to shooting azimuth, 24' elevation, 82 degrees and 70% humidity, only 4.1mil elevation and 0.4mil windage.....not ideal atmospherics for the new guy I imagine, and it was within 1 foot POA-POI with no chrono data and a noob driving! I meant to feed geoballistics 2625 velocity but put 2725 and it hit low for what ever reason. I didn't range the target but I was impressed as you can tell I'm sure.
So quick question, am I on the right track with the gas block being too far back and undergassed? (Brass ejecting between 3 and 4 with authority just not feeding next round at all or jamming on ramps, regular carbine buffer, 108 ELD Match factory loads.)
****HMMMMM, need to figure out HOW to post pics now...lol****
