Velocity difference between .222 Rem. Mag and .223 Rem?

[Dusty Stevens]

Dusty, your post was very polite. I am adopting the cartridge as a near favorite. I have a few rifles and have been buying high quality vintage brass. I have a factory sako and a re-chambered 722. I like to work extra hard on things that most people have moved on from. Other favorite is 6mm rem. My beard is gray and my hair is 90% gone. PS, your posts are a PHD in shooting and reloading.

You may have taken that wrong. I love the 222mag. I think its great. There were still guys winning br matches with it when i started shooting. I meant that its fallen out of favor with so many more popular choices, and components are not readily available so its kinda like chevrolet selling the dies for a 1987 truck door to an aftermarket company to produce because they just cant do it all. The powder and bullet companies have solid data for it they just havent revisited it since some of the newer powders came out. I appreciate the kind words.

I did not take offense in the slightest. Cheers.

All your problems have been solved. 22-250

^^^^^completely different beast"
No comparison at all!

No KIDDING that was the whole point. All this talk about which is better when there isn't hardly a gnats whisker difference. quit trying to hot rod the both of them and get a 22-250.

I'm not a target shooter per say but have won a couple of informal club matches and am a avid coyote hunter and back in the day did ADC work 1970's with a 223. I like to experiment with cartridges for predator hunting and am currently using 222's(40 yrs), 223(55 yrs), 22-204(16yrs), 5.6x50R Mag((15yrs), 22-250(40yrs) plus a number of smaller and larger cartridges. My favorites are the 222 Rem and 22-204(222 Rem Mag Improved 30 degree). As far as I'm concerned velocity capabilities of a cartridge isn't that important. Being able to hit what your shooting at with the first shot is. All of the cartridges are accurate enough to kill stuff.

If guilt edge accuracy is your goal there is no sense re-inventing the wheel there are cartridges out there that will shoot a .000" group, it just takes a shooter to do it.

The 222 RM is a great round, so is the 223, there isn't a GH, PD or coyote that will know the difference.

The military honked up when they adopted the wimpy .223 thinking it suitable for killing humans en mass.
It isn't and they have frittered away tens of millions of dollars adding longer heavier bullets at higher pressures to improve the performance. This required rebarreling a lot of rifles for the faster twist required.
Load the .222 Mag to the same pressures and it will be a few percent better than a .223. It is a good varmint round. I like the 6mm X 222 Mag even better.

If you are not married to the AR-15/M-16 cheap brass is the only reason to own a 5.56/.223

When they adopted it, the idea was a wounded soldier took at least 2 soldiers to deal with. Sierra uses the .223 for accuracy testing , so in equal rifles the .222 and .223 would take a very good shooter to ever tell them apart.
