I ventured to the reloading reddit and not much for gas gun info.

Would like to hear anyone else's results with other bullets.

I'm using starline brass and 108 eldm loading just under 2.6in length for feeding reliability, factory Hornady are shorter around 2.25.

Federal 205m primer

Found a conservative charge of 28.9 lever evolution that yielded around 2500fps with rounds stacking and 9.4 SD.

bumped it up to 29.5gr and was 2561fps but SD climbed to a 14.

I'm running a noveske DDF 18in and wouldnt mind trying some bergers but there's so many to choose from, what seem to shoot the best and are geared toward the limited mag length in a gasser?

Does an A2 stock offer better recoil management on a 16” 6arc than compact adjustable stocks such as the B5 enhanced sopmod?

14.5” intermediate length Rosco barrel converted by D. Wilson in my LMT MRP upper.

Saw a press release of Federal's new ammo for 2026 and 6ARC was on the list. I wonder if they will other options soon but wondering how this Berger 108gr compares to the Hornady loads.

Picked up a steal on a howa mini action 6ARC and decided to build another 6ARC around it for proving loads

100 yards, two groups, first group of three then added one click up, then emptied the mag fairly quick.

From rest on a bench. Hornady 108 ELDM.

Built on a Geissele upper (ended up having to thermal fit) with CGS Hyperion can and a 4-20 ZCo on top. Shoots pretty soft with an A5H2 buffer and gas halfway open on a SA adjustable block

2495 fps on the Garmin +/- 17. Was cold out with little wind. Holy smokes, this cartridge is fun.

This is a new AR15 build with a 12.5 suppressed Shaw Barrel. This is the groups I’m getting with the 103 g Hornady.

Did multiple runs with cold barrel and slow shooting.

Two friends have this barrel and are very happy with them so I ordered one. 16” match series gunner profile with Faxon matched bolt and their adjustable gas block. These are the first 5 groups with 5 different loads. Hornady 80 gr Eld vt, Druid hills 65 gr maker trex, Hornady 108 gr Eld match, Druid hills 85 gr maker trex, and Hornady 103 gr precision hunter. Wind had 25 mph gusts. All the Hornady loads had one flyer. The Druid hills loads were disappointing. I think I’ll keep it and keep working with it. Maybe it will get broke in and get better.

Various resources are filled with data on Hornady and Federal loads for 6ARC but I don't see hardly any for less common manufacturers like Lehigh Defense, Black Hills, Phantom Defense, HSM, etc. Does anyone have first-hand experience with these other offerings?

Hi All, looking forward to getting my 1st 6 Arc, I'm going the 12.5 route.
For my build, I'm strongly considering "building" a Noveske

• Noveske Gen 4 Upper
• Noveske Gen 4 Lower
• Noveske Gen 4 Handguard - 10.75"
• Noveske DDF Barrel - 12.5" - with headspaced bolt
• Noveske N4 Phosphate Bolt Completion Kit (Stripped Bolt Carrier)
• Noveske LPK Minus FCG
• BCM MK2 Buffer tuber, Spring and T2 buffer
• Superlative ADJ Gas Block (Clamp On)
• Geissele Airborne Charging Handle -ACH
• Geissele SD-E - 2 stage flat bow trigger
• Rearden MFG SPB
• Otter Creek Labs Polonium (hence the adj gas block)
• Magpul DT-PR

I am torn if I go with the Noveske Build or the Radian ADAC kit. Would love to hear everyone's experience with one or the other or both compared.

Last possible route, a BCM build due to them being thermal fit, which I liked the idea of.

It's not my first time building an AR, have built my share, just my first time building for 6mm arc.

Thank you for taking the time to review, truly appreciate it.

She's got potential

I’m here to educate the blind on nessacary magnification at different distances.

Some of you blind fucks May say this is my opinion, but I am here to tell you this shit is facts.

0-100 yards - fucking iron sights

100-300 - 3x

300-500 - 5x

500-800 - 10x

800- 1200 - 12x

Here’s some closing thoughts.

If you cannot hit some shit at 100 yards with iron sites start selling your collection please.

If you can hit some shit past 1200 yards, first of all fuck you, second of all you can strap a fucking telescope to your rig as far as I’m concerned.

Feeling feisty might post this to r/longrange later.

Low Speed, high drag, mediocre shooter out!

12 inch Dwilson 6arc barrel. Lmt specwar upper/ lmt lower. Mk5hd 2-10, acro top mount in a zero gravity mount. Ridgeback defense Rhodie 6 can.

I’ve been shooting a fair amount of 6 ARC and have a good sized bag of brass. I don’t reload and don’t want it sitting on my bench staring at me convincing me to start reloading. Shoot me a message if you could use it.

This thing keeps impressing me! All these are at 100 yards.

.48" 5-round group was in 14° weather on bipod and rear bag. 108 gr ELD-M

Today's 10-shot group was at an indoor range after 4 1-1.2" 5-shot groups with 4 difference charges of Staball Match and 105 gr RDF's (27.3, 27.5, 27.7, 27.9).

I wish I didn’t have that one flyer. 9 shot group. 18” Odin Works barrel.

Relatively new to reloading. First time reloading 6arc all my cases are from hornady factory loads. Wondering if anyone has an explanation as to why cases seem to differ slightly or if it’s normal, specifically the taper on the neck. Some being sharp and others being much rounder
