I've been doing some load data research online since I don't have the new reloading books and found that Sierra has more of a selection of different bullet loads than Hornady. Found this kind of strange as isn't this 22 Arc Hornady's baby as didn't they introduce this a couple years ago ? Maybe my time line is wrong but I think one might understand where I coming from.

Are there any other load data info out there other than these two I mentioned ?

This one has peaked my curiosity for a coyote caliber for sure, as much as I said in the past, I'm done with new rifles. :rolleyes:
 
What bullet you want to shoot dictates the range of powders you'll want to focus on

I'm almost through my 600+ rounds of factory ammo and will be handloading full time soon. IMR 8208xbr has looked very promising with 62gr ELDvt and Viht N550 shines with 88gr ELDm in my rifle

75gr ELDm factory @ 3000 fps is pure murder on coyotes
 
I have a number of 22 bullets on the lighter side and thought they might work but after doing some more research and what was mentioned above , the heavier bullets would better choice.

Tod, I've been following your thread on the 22 ARC and very impressed with what you have posted and that's what started the itch.
 
No reason why you can't shoot lighter rounds. Some litter varmint rounds just don't like to be spun and driven too fast, and will fail. But most lighter rounds will do perfectly fine at all 22 ARC velocities.
 
I built a CZ527 with a 26" IBI 1-7 barrel and it's a hotrod! Sierra 80gr MK at 3100, but have had them up to 3200ish without issue in Hornady brass. I got some Alpha brass from Go-Big, and did a repeat with 88 ELD-M and have those nicely at 3045 with itty bitty groups. I plan to work in that same charge area with Sierra 90gr MK.

Everything is with VV N550 and CCI450's

I've got some 62 gr ELD-VT that I'll be playing with this week once it warms up.

I'm loving the 22 ARC, that 88 gr load is supersonic to 1200 yards.
 
I've had incredible groups / ES with 85.5gr bergers, 29.0 gr Varget, almost touching the lands. 16.5" proof carbon barrel.

I might add that this load was very hard on brass. Maybe 2-3 firings tops.

For group size? Bullet drop? Impact speed?

Yes. For those of us not quite so connected to the hum and buzz of modern cartridge design, this is a new one. The 5.56 has its advantages and is a pretty good cartridge. But, obviously tweaking and tuning has changed all that. So what makes this wonder-chambering better?

With the short, fat case, you can have more of the bullet out of the case for increased powder capacity, especially in short magazines. A shorter, fatter powder column gives a better burn, and accuracy potential is better. The case of the .22 ARC is very similar to the PPC cartridges that dominate short range BR. The ARC, in its original form was intended for long, high BC bullets and the SAAMI spec freebore is designed to allow the longer seating of heavy bullets. Everything about it is geared towards internal ballistic efficiency while propelling bullets for maximum downrange ballistic efficiency.

The lighter bullets being that they are shorter, wouldn't they have a heck of a jump to reach the lands when fired ?

I was in the same boat a little while ago, as well.

That's fine. Some bullets prefer a jump. And it isn't always detrimental to accuracy. As long as your loading setup doesn't produce a pile of runout I guess.

I run some extremely light bullets in some setups, and they shoot phenomenal. A 110 grain flat based bullet in my 300RUM has an absolute massive jump to reach and rifling, and it's extremely accurate.

I like the 223, always have. Still own 3 of them and with the right loads they'll group right there with the 22 ARC at 300 meters

22 ARC will push heavier, sleeker bullets at more speed than the 223 in a apples to apples scenario. That makes for less drop, less wind deflection. And way more good long range factory loads than the 223 could ever dream of

One of the best reasons to reload. Shoot whatever bullets you want. My 6mm ARC, really likes the 58 grain v-max bullets. My son has a lot of fun at the range shooting this load. Cheap bullet, low powder charge weight, and tons of fun. And able to load it with heavy rounds for longer ranges of need be.

How is it any different then the 223 WSM? Isn't it kind of like reinventing the wheel?
 
223 WSSM is about 50% larger case than the ARC and was a 1:10 SAAMI twist rate designed for a 64gr soft point. It was designed to tap into the short mag craze of the early 2000s
 
Hmm, I stand corrected. I didn't realize the case was that much bigger. Is it recoil in the 223 WSM that makes it a concern? I was thinking the concept of a short fat case would be both the same in each example, no? And as far as twist rates go, barrels can be swapped to whatever twist rate you want to accommodate different bullet weights.
