New to the forum and new to the 6 arc. Have hunted all over the west and the backcountry of my home state of Idaho, and over the last couple of years have become more and more of a believer in smaller cartridges for hunting deer, elk, antelope, bear, etc - basically anything in the lower 48. Retiring the large rifles (7 rem mag, 300 rum) for a while and decided this is the year I build a smaller, lighter, rifle for my backcountry hunts. My wife and daughter shoot a 6 creed and 243 respectively (108 ELDM, 105 scenars, 95 NBT) and always amazed what those bullets did on game, so after much research, settled on the 6 arc.

Here is the list of the parts - right now I am only missing/waiting on the stock then can put everything together and start load development - HOPING TO HAVE STOCK WITHIN NEXT COUPLE OF WEEKS. 

Howa Mini Carbon Fiber Barreled action - 20"
JO Outdoors BDL Bottom Metal
Timney 611 trigger - set for 2.5 pounds
Stockys CF VG Desert Sagebrush Stock
Backcountry Banish Suppressor
Burris XTR steel 2 piece pic bases
Warne Mnt Tech Low Rings
SWFA SS 3-9X42 Scope

Will have action glass bedded, and barrel floated in stock. I do want to make this as bomb proof as I can, so probably will have the bases bonded to the action. Also probably going to have Kampfelds replace the factory knob with one of his campfire knurled knobs. Based on the parts I have in and an estimated 21-22 oz of stock and say 2-3 oz of bedding material weight - this rifle should finish up around 7 pounds 3-6 oz. Should be a perfect little backcountry mountain rifle and will save me almost 2 pounds off the custom 7 rem mag that I have carried the last few years...

I have a bunch of Midway 2nd 106 TAPs that I will shoot. They are a bit tougher than the ELDMs so I am upping my velocity threshold for expansion from 1800 FPS to a minimum of 1900 FPS for the TAPs. I should be able to get a good load atleast at 2750 FPS, best case goal 2775-2800. (Lever and H4895). But 2750 will get me out to about 700 yards with this little rifle.

As it comes together and I am able to shoot it and get data, I will load pics and information.

Currently have a 24” barrel but thinking of adding a suppressor . 
What barrel length are you guys using with suppressors and how much velocity loss to you get ?

Thanks

Looking at Lyman's 47th, there is pressure data for 6mm PPC with AA2015 powder up through 85gr bullets.

Has anyone tried it, or is there modeling software that includes both 6mm ARC and AA2015

On their website HERE, Federal Ammunition says a Gold Medal 6mm ARC loading with a Berger 108gr bullet is "coming soon."

Bullet is probably the Berger 6mm 108gr BT with a G1 BC of .522.

Would like to see the Berger 6mm 108gr Elite Hunter with a G1 BC of .559 — only .040 longer overall.

Or could have just used the Berger 6mm 105gr Hybrid with BC .536 and gotten a touch more velocity.

Sometimes I don't know what these companies are thinking: "Hmmm ... we have the choice of very similar bullets that would both work equally well, yet we have a chance to do something amazing from the ground up because we have a blank slate, but let's use the one that is technically inferior."

   

I have a 2 Magpul rifle stocks, gray, 
1. for Savage 10/110 short action (308, Creedmoor, etc). I like these stocks because they provide an economical upgrade from the normal plastic savage stocks, and have a wider cheek rest spot than the accustocks do - better able to get a good cheek weld. Easy to get stable on a rear rest at the shooting table too. Low, med and high inserts allow you to adjust cheek height.

2. I also have a ruger american magpul, gray, available. Same deal as for the savage one, this one will fit both gen 2 and gen 1 rugers, so would be a good, economical upgrade for your grendel/6 Arc. It also takes AI mags so the Mdt or comparable, AI style grendel mags would be needed (not included). I took it off of a 243 ruger gen 2 so I know it works on both (still have one on a 243 ruger gen 1).

Lightly used, can ship to lower 48.
Terms USPS MO or check (when cleared), Zelle is ok to. No paypal or Venmo.

Either one, asking $180 + shipping. PM me your zip code so I can estimate shipping UPS.    

I'm thinning out the herd...
So I have 3 Vortex scopes for sale, all are excellent condition, the 4-16’s are lightly used, the Strike Eagle is virtually new-in-box (mounted but did not shoot with it).
I've had great clarity with all of these, and still have several vortex's mounted in use. They're not $1000 razors, but are very good for target or field. The HST in fact, I've taken out to 600 and 1000 yds during a long range course, the 600 was an easy distance, the 1K I was about 25% and several near misses (wind calls), but that was mostly me I think. I have another DBT still mounted, very happy with it, and some 3-18 SE's that I like a lot (same reticle), so I can recommend these without any hesitation.

Terms are lower 48, USPS MO or check (when cleared). Zelle is ok too. No paypal or Venmo. Will be shipped UPS, give me your Zip in a PM to estimate shipping. Will need full address to ship. All specs of course can be seen on the Vortex website.

1. 4-16x44, Diamondback Tactical, ¼ MOA, FFP, includes sunshade. Asking $250+ shipping, lower 48.
   
2. 4-16x44 Viper HST, ¼ MOA, SFP. Asking $300+ shipping, lower 48
   
3. 4-24x50 Strike Eagle, ¼ MOA, includes sunshade. Asking $250+ shipping, lower 48.
   

I did a few searches on here and didn't come up with much. Have any of you ever seen a test or chart of velocity differences using the same ammo with barrel lengths from 14"-22"?

Thanks

The new Natchez Shooters Supply was in the mailbox yesterday and has all of the Hornady 6mm ARC ammo (except Hunter) for $26.99/box.

I have been looking at powders to start my test loads and decided I wanted to try Leverevolution. I was looking everywhere I could in my limited rural area only to come up with nothing. Nobody even carries it. There used to be a couple dozen places to get reloading supplies around here. 

I had a VA appointment today so I stopped at the local Runnings store that is out of the way, and wow there it was. Now I'm set to go, four different bullets, my powder of choice plus a couple others I already have on hand. I think its time to sit down in the reloading room. If the weather holds I might actually get to test them before it get cold or snowy again.
