Forming 6.5 Grendel Brass to 6mm ARC

[@TheDollarSportsman]

Right now I can’t find 6 ARC brass anywhere, so I appreciate this video!

[@RobsReloading]

Grendel brass is definitely more avail right now. That's why I got into 6 arc because I already had a pile of brass.

[@copisetic1104]

I’ve been shooting 243 for decades, it’s nice to know that companies and pro’s finally agree with me.

[@bubba7626]

I just picked up a Tikka TX3 in 243 with a 1in 8 twist so I can shoot the higher BC bullets a bit flatter at longer range

[@billcarlson852]

Love it.... Just bought starline, and lapua to resize...thanks for the help.

[@SimpleLife1971]

I really like the EP Integrations annealer. It looks user friendly and the price won't break the bank. Thanks for showing us your process!

[@nineby9879]

Found your channel on my recommended feed. Watched your other videos and subscribed. Content like this is quick, informative, and simple to understand. There’s no over explaining to make simple concepts confusing. I vote yes to videos like this too.

[@RobsReloading]

Thanks for the kind words. I try to use simple processes myself and have had good results in my reloading. Seems the most important part for me has been having a barrel that shoots, and using decent quality components!

[@larryd1296]

Nice sturdy reloading bench and press mount!

[@dahut3614]

It was great seeing this type of video. I do also need an annealer. I always thought that it looks like the the AMP Annealer _overheats_ the brass. I trim my brass on a motorized RCBS Trim-Pro. The cutters I use are the tri-way type that chamfer the inside and outside- very fast. It came with the used Dillon XL-650 that I bought from my brother.

[@mostrogolf22]

Well, I just did a major purchase for a 6mmARC barrel, BCG, Upper, etc. for my AR15 lower. Been looking at all the things I must do to obtain brass. Doing 223 for a while so another step in the evolution. Good video.

[@ElfstersRiflesandReloading]

loved the video! thank you! :) got to love that EP 2.0 annealer!

[@randyemenhiser2573]

I vote YES on videos like this

[@RobsReloading]

Will probably post 1-2 videos a month in this style going forward! These videos will go up Wednesdays at 7:30am EST

[@TNRay]

Just found your channel Rob, love the reloading content!

[@oif3vetk9]

I use a forster 3-in-1 trimmer. Love that thing.

[@elwhastrummer]

Frankford Arsenal trimmer is the bomb! I sized my Grendel brass, set it up in the trimmer, and trimmed 40 cases in less than 10 minutes. took another 5 minutes or so to chamfer and de-burr. Hands didn't get sore. Amazing how consistent my lengths were. I don't hold stock in FA. I've trimmed a lot of cases with the Lee cutter/lock stud, it works good but hands are cramping just thinking about trimming anything...let alone trimming from 1.51" to 1.48" (.030) I'm getting old...LOL..

[@grayshooter4475]

Good job, keep doing what you are.

[@waynemayle865]

Good deal Rob nicely done

[@joejr9653]

Very good video. 👍

[@Kycirion]

I looked at this annealer, but single loading is a huge no go for me. Needs to have a loading tray holding at least 50 rounds.

[@dahut3614]

The spec for 6ARC brass is 1.490" -.020", but the spec for the SAAMI chamber is 1.500". I read in a post on accurate shooter where someone said that it can take multiple firings to completely fireform a piece of brass. I was wondering how the brass length after firing of a resized Grendel case compared with that of an actual 6mm ARC case...!?

[@RobsReloading]

I can't speak to what happens with the actual 6mm Arc case because I haven't measured those. However with the 6.5 Grendel cases I had to trim them after the original fire forming. I ended up having to trim roughly 7 or 8 thou prior to the 2nd fireing as 6 ARC.

[@LastCaress7]

Great vid man 👍

[@chrisfisher3900]

Just picked up that annealer myself.

[@abimaelsoto9690]

love the video keep it up

[@HamptonFPV]

Love it. Thank you

[@scotturban54]

morning Rob 🌄

[@autospeedlift]

You should leave your case in the trimmer and debut it with power.

[@MrBoostin18]

Nice video. Thanks sir. My local academy has 2 packs of 50 - 6.5 Grendel brass. Thought about picking them up. Wonder how well the primer pockets hold up to the 62k psi bolt gun pressures.

[@RobsReloading]

So far I have some 6.5 grendel hornady brass, that was fired 1x in my 6.5 grendel, then 2x in my bolt 6arc. So far no issues with primer pockets yet.

[@jmkhenka]

Hornady brass gives up after 3-5 firings if loaded high, lapua hold 20 loads. But its 50-50 if you loose the primer or get to thin webbin, had 1 partial case head separation with hornady so now im inspecting them before primers goes bad, just in case.

[@Charles_ONeal]

I like this type of video.

[@briank8moe495]

What size neck bushing are you using?? Just found your channel, thanks for doing the video..

[@RobsReloading]

It's a standard full length Hornady 6arc die. It's not a bushing die.

[@robertdesantiago7063]

Everytime I run my 6.5 brass thru the Hornadiy dies to resize it they come out crushed .I am adjusting it as I do with all of my other bullet caibers. It just keeps crushing them at the shoullder.

[@RG-pd1ro]

When i did this it doesn't seem to bump the shoulder back quite enough..any tips? TIA

[@livingintheLight.]

Been making mine from x39. I made 50 from grendel and it's a lot easier, but you got to do what you gotta do

[@jmkhenka]

x39 is to thick walled, you loose alot of case capacity when doing that. Also large primers are not doing any favors on accuracy. Lost about 5 grains of power capacity over my lapua 6.5 grendel brass. But it can be done :)

[@livingintheLight.]

@@jmkhenka yeah, there's no way you lost 5 grains of capacity. Maybe before it fire formed. Large primers aren't ideal. Just tell me where to get some brass

[@DimaProk]

@@jmkhenka I heard Lapua has least volume when converted. Best if you use American brass and PMC, easier to convert and no "ring" at the base. When converting from 7.62 to 6.5G the loss was 0.7gr. I compared original Hornady to converted PMC and GFL - both had same volume. Will need bigger sample and perhaps 2x fired to get better data. Haven't measured 6mm arc yet.

[@brianmorgan6039]

Perfect video man! Thank you so much. I’ve been having to buy 6ARC ammo for over a year now and only have 220 cases. Absolutely gonna do this from here on out. THANK YOU! 2 question’s though… how are your groups on this resized brass and how many firings are you getting out of them?

[@RobsReloading]

Check out my 6mm arc series all groups on my channel are with resized 6.5G brass. So far I have 4 firings on this batch without any issues.

[@brianmorgan6039]

@@RobsReloading thanks buddy, I will. Just got my “Atheris” upper in that I ordered LAST MAY!!! Really hoping this bad boy produces good groups. Hoping to be my new coyote, hog, deer and antelope gun if she’s a shooter

[@RobsReloading]

@@brianmorgan6039 my 6 arc is the best shooting and easiest to load for out of the cartridges I shoot. It hasn't been hard to get single digit SD's and half inch groups regularly. I used my 6 arc in a local long range match out to 1k without issue.

[@brianmorgan6039]

@@RobsReloading thank you for that info. Is your 6ARC the savage switchback on an mdt chassis? Mine is an AR, but I hope it groups well

[@autospeedlift]

You should leave the brass case in your power trimmer to debut the case.

[@rustynut1967]

What headspace adaptor are you using, #400? You do know Grendel and ARC use a #350 for a datum point. It doesn't matter that much when comparing your own brass, but when relaying dimensions and info to others it can get confusing .

[@RobsReloading]

Yes, I modified one of hornady's bullet comparitors specifically the .28 cal, up to .350 to use as a headspace comparitor. As for any of the refernced data cbto, and headspace numbers shouldn't be followed across the board from one user to another due to manufacturing variance. These are what my numbers are not what your numbers should be. Use your set of comparitors to get your numbers for best results.

[@rickerdman9116]

Rob, how did you trim down your Lee 6mm PPC trimmer? Thanks!

[@RobsReloading]

Just with a basic metal file and a caliper to measure how much material I wanted to remove.

[@spacemarin04]

So you just have to run it through a 6 ARC full length resize die and trim ?

[@RobsReloading]

Pretty much!

[@spacemarin04]

@@RobsReloading you may have solved my problem. I've been wanting to do a 6ARC gas gun but haven't been able to find brass or ammo. Why build a rifle I can't get ammo for.

[@Jjhornet]

How did you shorten Lee trimmer? Just picked up savage 6mm arc but no brass available, thanks

[@RobsReloading]

6 ppc trim length is 1.505" per sierra load data, so I only needed to trip roughly 20 thousandths off, to get to 1.485". I just used a standard metal file on the bench and filed it by hand. I gradually filed on the tip of the Lee case length gauge until I was happy with the length. It only took a few minutes of filing/measuring to get it right.

[@Jjhornet]

@@RobsReloading thanks

[@frankhelton5591]

You can trim and chamfer without pulling it out of you drill.

[@rodneymoore7270]

It's good not to burn the house down.

[@larryd1296]

You are NOT annealing that brass at that speed!!! Do the research!!!
