which primers would be the best for reloading .223. I know there are different levels of power and i not sure which one would be the best to use. I want to be safe.
Thanks in advance for all the help.

CCI Small RIfle makes good primers for ARs.  I like the CCI #41s and the CCI 450s.  They cost around 35$ a thousand if that helps you.

There are several manufacturers who make primers in small rifle size.

You would be best advised to follow a complete recipe when you start out.
That means that the brass, projectile, powder, primer, and overall length, should be followed exactly as given.
Get some reloading manuals and start by cross referencing as many as you can.

As you get experience, you will learn more about the differences between primers from different manufacturers which are supposed to be the same.
Even brand changes within the same primer type have an effect on a load. Some effects are not significant, but some are, so start by playing it safe.

Here is a fair article on 223 reloading which lists some of the many choices.

Use the primers called out in your reloading data is the best way.

Avoid Rem 6 1/2 and Wolf Small Rifle, as these two are for use in low pressure rifle rounds, not 223.

So Rem 7 1/2 and Wolf Small Rifle Magnum would be the correct choices in these brands.

I use Rem 7 1/2 in both my Grendel and my 223/5.56.

For regular 55grn and 62grn bullets, I use Win Small Rifle primers.  For my long range 68grn bullets, I use Remington 7½.

I use Rem 7 1/2 for precession loads. (match bullets)

Win SR, Wolf SRM, CCI 400, Magtech 7 1/2 for everything else. Whatever I come across at a good price.

Haven't tried the Tula SR I have yet.

Wolf, its all I am using in .223/5.56 loads anymore.  ES and SD numbers are juts as good as CCI BR primers, and they are a lot cheaper.

CCI #41 or Rem 7 1/2 are the best and safest primers to use for loading 223 for use in an AR.

I doubt there is a SR primer I have not used and can not fault any of them.
Whatever you find a good deal on, use that.

I now only order Wolf SRM for my 223/5.56 loads and even use it for my match 52, 69 and 77gr loads. I just did not see any difference.

Perhaps if i was loading a 77 or 80gr 223 for a bull bolt gun.
But, in semi auto the primer exceeds the other components in consistency so I prefer to save the money

Based on my experience so IMO

Work up your load and let your gun do the talking not some internet informal poll.

An all around given is do not use Rem 6.5 they are meant for 22 Hornet and 30 Carbine loads and the Wolf Small Rifle primers are fine in a bolt gun just not the AR. Personally, ever since Winchester quit plating their primers way back in the early 90's I have not used them for AR 223 loads due to some issues related to pierced primers.  

There is no power level, per say but rather the brissance of the primer and the hardness of the cup..

The Rem 7,5 used to be labeled as a Small Rifle Magnum primer, but now is labeled as a Bench Rest. I believe that it is one of the best all around primers for the 223 in an AR platform or a bolt gun.  

I would do what prudent reloaders do, work a load up let the gun tell you what works!  Granted no problem pointing a person in the right direction.....just do not cheat your self by blindly choosing only one primer....
