    I've never found a difference between CCI, Winchester, Federal in small rifle primers.

    As jpattersonnh says, they are all good. I don't have a bolt .223, I shoot an AR and a Mini-14, so I load with the CCI #41 primers which have a harder cup like military primers. But I've never had or knew anybody that had a slam fire using regular small rifle primers in an AR. I have a slight preference in my pistol and larger caliber rifles to use Winchester primers.

    For the Howa, Fed, Win, CCI, Rem. If you are looking to wring the absolute nth degree of accuracy look at match/benchrest primers.

    For ball powders in cold climates, try magnum primers

    Started reloading .223/5.56mm in the mid to late 60s. This year i have loaded over 4,000 rounds. My favorite .223 primers are Winchester followed by CCI. Other brands would likely work just as well.

    I use whatever is availble, but if I have a choice, I prefer Rem 7 1/2. They are Magnum primers and work well in my 5.56 and my Grendel.

    The Remington primers is what my reloading guru turned me onto when I started reloading .223. I use them for both my AR loads and my bolt gun.

    I concur. I have worked up loads for each primer and have not been able
    distinguish a difference in .223 Remington/5.56 NATO or any other rifle load.
    Now this is with standard Small Rifle primers, I was not comparing Magnum,
    Bench Rest, Mil-spec or other types of Primers. Also true with Large Rifle
    primers with the same exclusions. Also Federal and Remington Large Rifle
    Magnum primers are interchangeable.

    IMO the relatively large charge of propellant negates and small differences
    in rifle cartridges. However, it would be prudent to work up loads when
    changing primers just to confirm there are no differences in your load and
    firearms.

    I have seen differences in pistol loads, when using different primers.

    Just make sure your Rem primers are 7 1/2 not 6 1/2. 6 1/2 are not to be used in the 223/5.56.

    Don't you mean in semi automatic rifle, particularly AR-15/M16
    rifles with free floated firing pins?

    Thanks heaps everyone .....in my Howa .308 I have found a significant difference In what primers to choose,when I started load development for it I used rem 9 1/2 primers CCI and Federal 210M just to see which one would work the best,I found for my particular gun that the Federal 210M primers shrunk my groups significantly....on the other hand I have a mate who owns a CZ-223 bolt and tried different primers in his load development and found no difference at all hence why I thought I'd ask the question what do other people use in there .223's...I've never owned one personally but I will try the ones that you's recommended and will post my results when done...just to mention that I will be using this rifle primarily on foxes and feral cats.....cheers

    Fed 210M are match grade primers, if you used their regular primers I would
    expect no difference over the rems or the CCI's, just my 2 cents worth...

    No, I mean any 223 or any other high pressure rounds like the 204 and the 222.

    Says so on the box and also on Rem web site.

    In rifle cartridges, the 6-1/2 small rifle primer should not be used in the 17 Remington, 222 Remington, 204 Ruger or the 223 Remington. The 7-1/2 BR is the proper small rifle primer for these rounds.
