    Planning on using CCI #41, Alliant Reloders 15.

    Anyone using this load?
     


  2. You trying to match the MK262?

    Is this a compressed load?

    Yes, but that's normal with the .223.

    any special precautions to take with compressing the load?

    also, what difference does the primer make?

    I know htere are some differences with small rifle primers.

    I would start at 22 grains and work my way up to 24 at 0.5 grain increments; i.e. 22.5, 23.0, etc. Just make sure you set your COAL as recommended and not any deeper.

    I've used CCI small rifle, CCI military spec primers and Winchesters and have not noticed any difference. Wolf makes a .223 specific primer now (I saw them at Powder Valley's site). Wolf's small magnum rifle primers have a harder cup than their regular small rifle primer to alleviate slam fires, but having a slam fire in an AR is pretty hard to do. As long as you seat the primers correctly, slam fires just don't happen.

    I use CCI's in my 223 loads and I seat mine way out but that is for my bolt guns and probably wont feed in your AR. You should not have any problems with compressed loads in the 223, they almost all are.

    Heaviest .223 load I have assembled for the AR was 65 grains.

    But FWIW, I love Wolf primers - and although I know the chance of a slam fire in a properly loaded round is very slim - I like the Wolf magnum primers as a way of emulating the "military spec" primers.

    Also, I use Wolf primers in everything now and have had 0 failures or negative issues.
