6mm ARC vs 6mm Creedmoor vs 243 Win. Which cartridge would you choose? 

Just an FYI if it helps.... the 243 with a 1: 10 twist will also shoot the 103 eldx. I'm for the 243 over-all. But the 6mm creedmoor is a great round also. But you can't drop down, probably past a 75 to 80gr bullet. And the arc, in my personal opinion out does the 6.5 Grendel. It's faster etc.

I just bought a Tikka T3x in 243 Win and finished working up a wonderful load using the Barnes 80 gr TTSX running 3378 fps. With all the new calibers being developed the 243 Win is not the sweetheart of the ball but it is probably the best crossover caliber out there. I am very excited about using mine on everything from Deer and Antelope to Coyotes.

A few years ago I had a shoulder injury and had to ditch my regular 308 or 30-6 because of recoil or I wasn’t gonna be able to hunt. I had a 223 bolt action but for taking whitetail at 150 to 200 yards I just wasn’t comfortable with it. I had missed some work because of my injury so $ was tight. Ended up getting a cheap 243 savage axis but I didn’t splurge for the heavy chrome lined barrel and chrome bolt. Stole a good scope off another gun and I was blown away by the light shooting and accuracy of the round. At first I was wondering if 100 grains was enough but the first time I watched the partition pass through a big buck and just fall over I was sold. My shoulder ended up healing but I still find time to use my cheap 243 because of how effective it is. The rifle was cheap but the round is amazing!

i would choose the 243 cause you can get ammo any place.. 100 grain slug and you can take down deer and alot of people have used it on elk with great success. remember bullet placement and if you want 55 grain for varmints !!

Dave, Thanks for sharing. When I watch your videos I get educated on thinks that I know little about. Take care.

Hi Dave , definitely the 243w and in a Traditional timber stock ! I have a Weatherby 243w and hand load for it , Hornady 87g vmax shoots unbelievably good . Stick to what you no , 243w has been around for a long time for a reason !!!!

Thank you. Good stuff

Hi, thanks for the video, Johnnys reloading bench has started some load work ups with the arc, its starting to interest me more and more

Trying to find ARC and Grendel ammo has brought me back to 308. Federal 168 and Speer Gold Dot 168 are more plentiful, and I know exactly what they do from a 26" 700 heavy barrel. I can't find enough ammo to shoot ARC or Grendel to switch short guns from 7.62x39

I love that Weatherby Camilla, I have a Vanguard S2 in 25-06 and it is such a great rifle for the money spent. My 9 1/2 year old son and 13 year old nephew shot 75grn Vmax's out of it yesterday with no problems at all. That Camilla may be one of the most overlooked rifles out there. Talk about a good predator calling rig.

In my way of thinking, I think that the 243w was created as a very noble hunting rifle, but with a broad spectrum (like antibiotics), that is, a rifle that can be used to hunt vermin, as well as to hunt larger animals, it seems to me. that one must define more for the use that is going to be given, and customize the use of the caliber, in my case I really like shooting and also the hunting of larger animals such as deer and pigs, so I put a barrel on it with a 1-7.5 groove pitch to shoot heavier bullets with a higher ballistic coefficient, and I achieve better firing groups and more energy in hunting shots...

Great discussion 👍. If I had to choose one it would be a 243 model 70 but a mini action 6 mm arc would be very attractive. I've also thought a mini 14 rebarrel to 6mm arc would be awesome. I'm hoping CZ will come out with a 6 arc 527 would be a lot of fun and perfect for my wife son. Thanks 👍🤠

I love my Tikka .243 T3.

Nice subject... for reliable feeding in a deer hunting gun I would choose the 243 because of the shoulder taper and short bullet seating length outside of cartridge. For coyotes I would probably choose the 6mm arc in AR platform for the quick followup shots on misses, on running shots, or multiple coyotes. Creedmoor for competition setup. They will all hunt, and all can be reloaded to be accurate and consistent.

If you're handloading, there's a great 6mm cartridge that you're overlooking. The 6x45mm. It's based on the .223 so brass is plentiful, is therefore AR & bolt gun compatible, and can push an 85gr TSX at 2800 fps. The 6x45 is simply a .223 case necked up to a .243 bullet. It's been around since 1965, but no company has yet to standardize it.

Savage has released several of their factory offerings now in 6mm Arc. Just order a left hand Savage 110 Tactical in 6mm Arc. With that setup in a 24” bbl should make a nice shooter.

I like the idea of the arc in gas gun. I think it be a great deer rifle for kids and women, I'd use 80 ttsx. Atm I use howa mini action in 6.5 grendel 20 inch heavy barrel 8.1 pounds with scope and bipod I use the 115 ttsx

"Cogitate", Damn good word. :)

If you reload the 6 creed is better in my opinion. I’m loading a 90grain Berger boat tail target I use coyote hunting and getting 3215fps out of a 20” barrel. Super accurate and flat shooting

My experience as a manufacturer, the 6mm ARC is by far the most accurate caliber I’ve ever seen. They are all great calibers, but my money goes to the 6mm ARC for my personal rifle. Coyotes have no issues with the 108 gr match or 103 gr Precision Hunter. My 6mm ARC in an AR shoots sub 1/4” all day. My 243 AR isn’t far behind either. I still haven’t brought myself to bring a 6mm Creedmoor home.

Nice

You stated the numbers. 6mm ARC should be a lot less of a barrel burner than the other two. Also, since shoulder surgery that’s something I have to watch out for as to how that relates to increased recoil, a big deal to me. That’s why I have a couple of 6.5 Grendel and why I built a 6mm ARC (which I haven’t shot yet). These may be my two AR’s going forward, if ammo prices will drop a touch. Of course, I reload, too.

I have a Unitah bolt action in 6.5 Creedmoor. I will be buying 6 arc from them next.

My NEW rifle was a 6mm Remington... of course it's 50 years old and only cost 400.00 with good glass. I picked up 4 bags of winchester brass for 40.00 a bag... I already have plenty of 6mm bullets and powder and primers. Try that with your 6mm credmore, 6mm arc,, 6mm western or 6 mm LATEST FAD.

Dam! that timber stocked 243 is an amazing looking rifle your a lucky man its beautiful. I've just bought 2 Ruger M77 Mark ll all weather skeleton stocks a 270 and a 243 their 20 odd year old rifles both in excellent condition because of the zytel stock im thinking , timber is nice looking but for hunting the synthetic are resistant barstards.

I can’t look past the bridals hanging on the wall long enough to focus on the cartidge talk

I couldn't let go of my weatherby 243 win but I can change barrles .

I have fell in LOVE with 6ARC in gas gun. I'm gonna use 100g Partitions for Deer and Hogs in 2021. The 6ARC fits my needs because it's an AR15 Platform. The 6ARC is more efficient than the 6.5G . The 6.5G will carry more energy up to 300 or 400 yards. Very similar to 308 Vs 6.5cm when it comes to energy

savage is making a chassis gun in both 6.5 and 6.0 creedmore but it cost much more than Thompson 243. but savage also makes a cheaper chassis gun in 243 but I don't think the action is as smooth as a Tikka. I hear Howa is a nice smooth bolt also. their chassis gun is cheaper than Tikka but I think its only 6.5 creedmore. To me the 243 in 95g is flatter than the 6mm. the wind drift is better on 6mm but I don't plan to shoot on real windy days. I'm not getting it for hunting just target shooting long range.

Uintah Precision makes an ar-15 upper (bolt action) chambered in 6ARC.

Have you seen the 6mm Super Long Range, it is a combination between the 243w and the 6mm Creedmoor, a 243w with shoulder and neck of 6 creedmoor....

What stock is that on your ar10 and that's one nice precision rifle

yeah i'm trying to make the same decision myself. I know I want the chassis type bolt gun. but I like the Tikka and I don't think they make it in 243 think its only 6.5 creedmore. 'But Thompson center teamed up with Smith and wesson and made a 243 chassis gun. So I was thinking like you I can get the grendel in a 20in and just get the upper bc I already have the lower and then get a 243 chassis gun. "But the most common caliber is 6.5 and I don't know if I want the extra recoil. but I also hear that the chassis gun weight about 20 lbs so maybe the recoil would be like my deer hunting 243 rifle. have you shot the 6.5 chassis gun how is the recoil compared to a 243 deer rifle?

Gas gun 6mm ARC, bolt action 6 creedmoor. My opinion is the 6mm ARC in a bolt action is mainly for competition. I think barrel selection would not be as good for 243.

Go with 243 AI

Let's see.....no experience with the 6 ARC or 6CM. The venerable .243 Win can do everything the others can do, however the same can not be said for those others. Good luck finding ammo on the shelf for those others to boot.

Love that rear butt stock. That would work out nicely for my Remington 700 PCR ENHANCED IN 6MM CREEDMOOR

243

Would the 243 win be if it from a 1n8 twist barrel

A 244 remington or 6 mm is best overall vs 243 and the new kid in town

Dave.. Join the 21st century!

I've been using a 243 Winchester way before those other cartridges were even invented. I rebarreled my 308 bolt guns that were collecting dust to a 1/8 twist custom 243 Barrel and have 26 and 28 in. The factory 243 barrels are either 1 in 10 twist or 1 in 9 and that limits you to a 90 grain or lighter a lot of people shoot 100 grain flat base with that. Once you get over 90 grain you get random wobblers. 6 mm Creedmoor and the 6 mm Arc have Factory Barrel setup for high BC Bullets. if you want to shoot the high BC Bullets out of a 243 have to get a custom Barrel. When you take on a new cartridge then you got to buy a bunch of new brass new equipment. Right now everything is in short supply and probably will be for the next several years so my opinion is stick with a 243 if you already have a couple of those then you can just add to your 243 brass and everything is interchangeable and get a custom Barrel that lets you do everything the newer cartridges do. I make 243 Winchester out of 308 by running it through a 7mm08 die then a 260 Remington die then a 243 Winchester die so if you have any range brass in any of those cartridges it could be made into 243

I’m guessing you have a 6.5 Creedmoor

Bolt gun: 243 Win. AR: 6mm ARC

6m/m arc can’t keep up with the 6 creed or the 243

.243

you need to check out the 6mm remington it smoke all of them

Uintah.

None of them The old 6mm remington.
