223 vs 6 ARC vs 6 Creed

[The Guide]

Hornady loads 88gr ELD-M in factory .22 ARC -- but not in .22 Creedmoor.

7 twist vs 8 twist on the SAAMI approved print. 22CM speeds the 88 ELDM isn't a fan of an 8 twist. At 22 ARC speeds, an 88 in a 7 twist shoots great. This is what I assume. Sounds like the 22CM should have called for a 7.5 ot 7.7 twist barrel for the heaviest bullets yet still not spin the light boys into dust.

The 223 will do what you need most efficiently.

If something else makes you happy and you don't mind the trade offs (predominantly cost to shoot), then go for it.


Don't think that matters for the ranges the OP is talking about.

Yeah, I know he doesn’t need it. But the trade offs for a factory 223 are that you are limited to its case capacity and length. A 22 ARC solves both limitations neatly. The only factor that even matters is cost per round, and that’s where the 223 eats the 22 ARC’s lunch. If cost were same-same, we’d have to go to mag capacity or factory ammo availability as deciding factors. I have not yet purchased a 22 ARC, but I may eventually. I do have several 233’s. But Hornady has my attention!

Happy Thanksgiving

To answer your question - no. There’s no appreciable advantage in your use case. What’s the minimum caliber you can use for hunting in your state? If 243, then get something 243 cal and above. If not, get a 223 and shoot 77 TMK or 73 eldm.

Any gain shooting high BC heavy for caliber bullets doesn’t really matter 400 yards and in.

6 arc for whitetail over .223

 

[Dave0317]

Yeah, in bad wind with strong gusts my 223 is limited to about 60 yards, my 243 is limited to about 100 yards before a 15-20 mph gust will move impact more than 8 inches. No way to call a gust, so in those conditions that represents max range. Regardless, you have to get close, just how close.

Is this a typo or a math issue?
Even at 6 arc velocities, i’m calculating more like a 1.4 inch wind drift at 100 yards and 20 mph wind.

It is a memory error. Thanks for catching it. Here are better numbers.

Thread 'Determine max effective engagement range'

Jun 24, 2024

This thread is an extension of the thought process that trigger the wind number thread. https://rokslide.com/forums/threads/wind-number-and-caliber-cartridge.362572/

Basically, the realization that wind can matter inside 400 yards and the frequently repeated idea that wind doesn't mattering out to 400 yards is not true. At least not in the conditions I hunt.

Obviously shooting in field conditions and logging hits/misses is the best way to establish max effective range. However, my shooting skill has improved significantly and I am currently hunting, so max high confidence range...

Well, i own and have shot about all of these into coyote, whitetail, and various varmits.

223, 1:8 twist will be your economy king & give lethal whitetail results out to that 300yd line. I handload a 55sp into mine for about 30 cents a shot. Use it alot for varmit & vermin as well as 500yd steel. That being said, wind kills the 223.

6 arc, I get about 300fps slower with that than my 243. Shoot 85 sierras, 105 hornady, and 112 matchburners outa it. The 112 has a 624 bc, and 2700 fps, and is plenty for a proper shot placement on a deer.

6.5 grendel is slow 6.5 cm. I shot alot of 95gr vmaxes at about 2900 outa mine. The 123 sst takes deer as well.

Favorite? Well the 6 arc is a better balance between the 223 & 243 than the others. 243 being probably my favorite whitetail cartridge. I need to try my 25-06 on a deer, but I doubt it will kill any better than my 243 does. An 85 to 105 gr 6mm is absolutely lethal on deer, and im my experience has done better than the ones I've shot with 300 mags.
