22 ARC, the 22-250 killer

In a previous thread asking what cartridge you want Hornady to develop, I don’t think there was one request for a 22 cal cartridge based on a grendel case.

Nope, was not on any bingo cards here lol. But millions and millions of Americans with ARs might feel different. Can dig it here from an efficiency point of view.

The 22 ARC will flop, no different than the 6 ARC did.

6 ARC already flopped?

Seems to be plenty of demand out there still.

Barrel life calculators…
The 55 vmax isn’t a boat tail bullet.
You’re leaning on the twist of the barrel being able to shoot high bc bullets. The comparison has little to do with the cartridge.
Even still, up to 500 yards there is no difference between your selections.

Barrel life is a thing, for some more than others

Pick your 14 twist boat tail bullet of choice and the numbers can be re-run

The numbers just get worse Bucky lol
 
This is what happens when you run ballistic spreadsheets based on theoretical dream hunting situations, add a dose of marketing, touch of thermal and pretend steel targets can grow fur. Entertaining. Mildly.
Carry on tod.

No, it's actually just math that affects real world results.

You're similar to the guy at the range who was surprised at how much energy my 22 Creedmoor 88gr ELD-M had on the steel at 600 yards. (~1100 ft lbs, BTW) "It hits way harder than my 75gr ELD-M from a 223!" Yeah, no surprise there! Ballistic coefficient matters.

Yup.

The math determines how well the cartridge fills the box of a truck, to a very high degree. It is inescapable fact.

It also determines how fast you need a new spout, what kind of firearm you can use the cartridge in, how much powder it burns, how much it recoils...pick the one that checks your boxes.

Dunno why numbers bother people so.
 
Is this the hunting sub-forum?
BC matters very little when I’m killing game. But let that not stop the dreaming and pretending about killing coyotes with your ARC at 600yards.

Who says no one does? Or likes to shoot that far with their hunting rifle?

We need to be limited to what you do?

Its gonna hit harder at 50 yards than anything else coming out of a .224" AR mag too. No need to focus on 600 ;) Sounds like a great way to launch 77 grain LRX or other nice monos. Or put light ones into warp high speeds with comparitively little powder.
