It's a shooter.. 62 grain ELD-VT showed up today! Was in a time crunch so no velocities but was shooting factory 88's

So I finally got the 22 ARC cartridge drawings. It is a direct 6.5 Grendel neck down to 224. Just like 224 Grendel, I was thinking there may be legal difficulties which is why SAAMI has not posted. Got this off youtube specialicedynamics post. Regardless I may dive in. This must really **** off the guy at eagle eye who was starting to commercialize to 22 DPC. A 224 necked down 6.5 Grendel.. Not sure about his clambering, I have watched many of his videos. I will give the cartridge one thing, it seems to be insanely accurate. So if you have a ton of 6.5 Grendel brass you can neck downnand shoot in a 22 ARC chamber. Like the you tube post I would do a two step neck down . 6.5 to 6. 6 to 224.

The 22 DPC is a necked down 6 ARC. Yeah no doubt he spent a lot of time on it. But he's on Hornaday's list of 22 ARC partners. (Desert Precision Gunworks) He definitely knows his s$&t and will certainly reap the rewards by supporting his existing 22 DPC customers along with 22 ARC customers.

Kenny's was a 6arc case necked down, not a 6.5 grendel like Hornady's 22arc is based off of.

Well I'm on page 5 of this thread and.....

Take the numbers hornady puts out and subtract at least 100fps first off lol. I know this because I've shot hundreds of rounds of factory 300prc ammo!

The 22ARC is not what is going to "beat" a 22-250.....the BULLET that the 1:7 Saami twist rate 22ARC pushes IS! That 62VT is a totally different animal than what we are all used to in a 22cal! A 62gr bullet with a G1 of .395.... thats almost identical numbers as a 73gr ELDM!

You can't fit a 22-250 in an AR15...
A 22-250 loaded to 52k psi is going to be kinda boring...
Barrel life is going to be better in a 22ARC vs 22-250
A 60gr in a 10tw 22-250 is going to run out of its speed advantage at about 400yds compared to the 62grVT in the 22ARC.

Yes you can do a 8tw 22-250 and put a lot of freebore in it and run the heavies....heck we are all seeing it done in the 22cm as well. But are you going to jump a 55gr bullet all the .000"s in a chamber set up for the 80's in a legacy type cartridge??

From what I'm reading the 22ARC will push everything from 50gr to 88gr while being loaded to fit in an AR15 mag.

It is not designed to out run the 22-250 at the muzzle.....its designed to walk away from it in that 400-800yd range and do it in an AR15 platform.

All these speed numbers are in the vertical plane which means squat because we can all dial for elevation! It's the wind that hinders ALL of us! You can put all the fps's behind a bullet that has the BC of a ping-pong ball that you want and judge that wind at 400yds @ 10mph from 1 o'clock and it actually be 15mph from 2:30 and that 6-7" wide chest on a coyote might as well be the width of a cigarette with that .250BC 55 grain 22-250!

I'm not bashing the 22-250 and I'm also not going to say that a cartridge with 10 grains less capacity is comparable to the 22-250. I know that if I have a dog hang up and sit down at 500yds and I got 1hr left in a 24hr contest....... I want all the BC I can get! Keep your speed and increase my hit probability left to right!!! You will get more BC from a Saami 22ARC than you can with a Saami 22-250.

Hopefully I can make cases out of my Grendel brass. And I cannot wait to put a 22ARC in a howa mini with a 24" barrel!!

22 ARC is a direct neck down from 6.5 Grendel. So 6.5 to 22 ARC no problem. Probably two step fit to 6mm then 22

Yeah I use lapua brass so I will most likely use a .275" bushing then a .255" in my Grendel die......or somewhere in that area.

2800-2950 seems to be the magic #Hornaday trys to get for all there new cartridges with their eld m bullets

Here's another way to spin it, a straight .223 in a 24/26" bolt gun will do what a saami loaded 22ARC will. And in all things practical, enable more commonly producible accuracy by the shooter. Shooting Pdogs off a tripod? 18lb bolt gun all day. I load mass quantities of .223 on a Dillon. 75gr at 2930fps with 8208. I bet factory ARC ammo will be 2900 - 2950 based on how hard I have to step on my 22 Grendel to get it to 3000fps

Been working on some loads 22ARC 20inch barrel Uintah bolt action upper. Shooters World Match gave me 100fps over CFE223 with similar accuracy and $10 a lb cheaper! 4350 was accurate but had to be compressed a lot! FPS with 31.2 grains of 4350 and the RMR 69's was just shy of 3000.

62 grain ELD-VT
32 gr shooters world match no signs of pressure.
4-3 shot groups 12 shot avg fps 3331
.280 moa was the best group, coal was 2.240 working up/down from there hopefully a nice long node?

69 grain RMR
32 gr shooters world match with a hint of pressure signs.
4 shot avg fps 3275
.760 moa

Played with lighter bullets mostly to see if they would hold up in the 1:7 twist, 50,53, and 55's they did well. I'll leave the light work for the 204. And focus on the 62VT and 69RMR. Next week I'm going to find some sunbathing PD's to test the splat factor!

Sounds like it would be neat in a ar. I run a 6.5 Grendel at night with a thermal. Wonder what the energy difference of the 2 would be?
Might have to try that bullet in my 250 and see how It likes it vs the 52s. The bc sucks on them. But running at 4K fps it overcomes some of that

 

[Farmerbrown32]

I got a 20" satern 1-7 twist rifle gas barrel. Shoots great. Very mild recoil. Shooting the 53 grain vmax at 3470 fps. Got way over 3500 but had a little ejector swipe. I need some 62 grain eldvt!

In full disclosure I haven't read all 8 pages of this thread, but I have a type s Grendel die, what seating die should I buy?

 

[MaxRager]

New Lee dies.. I'm not a Hornaday sizing die fan. Just ordered a set of the Lee dies hoping to get better neck tension?
