I know a lot here are not huge AR fans.
I just got a 6mm Arc upper that I am planning on using for my whitetail rig for next season.
Would like to hear from anyone who has used the 6Arc what bullets are you using as well as powder.
Im going to pick up some factory stuff today just to get the rifle lined up and I know most factory stuff for it is 103,105 and 108gr. I know they have the 80 but prefer to shoot a bit heavier bullet than that.
What are some of you all using and have had success on deer size game with the 6 Arc and also what powder are you using as well.
In doing some reading I see a lot like the Leverevoloution powder, but I hear its pretty dirty. I was thinking of using the CFE223 with something like a 105 gr which seems to get good velocities also.

So what all aare you guys using with sucess.

I recently got a 6arc and have put a few rounds through it. The only thing I have shot have been the factory 108gr ELDMs and it really really likes those. Not sure yet what I'm going to use for a hunting bullet out of it. I've picked up a couple of pounds of LEVERevolution. It is supposed to be a great powder for the ARC with really good velocity.

Here are some of my load workups and good loads with my favorite 6 ARC AR. I've used mostly LVR, it gives best velocities and good accuracy, but is temp sensitive. Recently started trying CFE223, AA2520 is another good candidate.

I killed one deer a few years ago with the 100gr TGK, and two this year with the 103gr ELDx, both worked well, I think the consensus is that the TGKs are a bit harder bullet.

For ~100gr to 108gr, I've found right around 29.3gr of LVR to be kind of a sweet spot, to the point that with a new bullet I try 29.1, 29.3 and 29.5 to start and see where things go from there.

If your gun shoots 108 eldm factory ammo, I wouldn’t mess with anything else.

Keep your brass to reload with 108’s again later if you really want to, or sell it to fund more.

That bullet is a certified killer at this point.

Not much to be gained over the factory 108’s unless they don’t shoot in your gun.

I picked up some 107 SMKs to put over LVR and see how they do. Also got some 95gr LRX to tinker with just because. If nothing beats the 108 ELDMs, I’ll stick to them.

I shoot 108s over varget in my Howa mini. I'm not one to chase speed they seem to kill just fine at the ranges I shoot them at. I had an AR upper that I never could get the accuracy I wanted out of used a good bit of lvr and CFE223 trying to find a load it liked.

I have a bunch of 87 grain hornadys loaded for breakin. I will switch to 103 grain eldx there after. I hope to does as well as the 243 with those. If not I’ll go to the 90’s.

108eld and 8208, 2450fps w/18” barrel. It’s warm for a gas gun but very consistent/great accuracy. Chose 8208 for temp stability as I built it for a hot weather pronghorn hunt for my kid. Total game sample of 1, so it doesn’t mean much but was instant death on a pronghorn @300 yds.

Temp stability is pretty important for me as for us here in Missouri it can be 80 degrees in November or 10 degrees. And can vary a lot from one day of season to the next.

For you guys shooting the LVR. Have you seen any issues with temp stability?
I have heard that it isn't very temp stable and that was why I was planning to use Varget even with it being a slower velocity than say LVR.

I have read that the 8208 works well, but haven't ever looked for it on the shelf. That's another thing for me is ease to find the powder needed.
