primers ?

I have been using CCI BR-4 for my benchrest shooting with a Colt target competition AR. Is this a good choice or are there better primers to be using ?
I read that wolf small rifle magnums are really good but none to be found.
so what is a good replacement for the wolf small rifle magnums ?

For 223/5.56, my experience has been that CCI 400, CCI 450 & CCI BR-4 primers could be used interchangeably without impacting velocity numbers, function of the rifle or point of impact.

As always, follow safe reloading protocols any time you change a component and work the load up anew. That way you will know for sure whether the standard, magnum and bench rest primers work the same with your load in your gun.

If your groups are satisfactory, no need to change. When my 5.56 groups with ccw 400’s were looking way too big, I tried redeveloping with cci 41’s. Results were marginal still. Then with cci 450’s, wow huge groups size improvement...maybe 30% improved.

I use the CCI BR 2 primers never had a problem , you CCI BR 4 I think are perfect for your setup. . Try not to overthink . The quality control on those primers are very good. Your uniform your primer pockets , only have to do it once , you can check the flash holes with a proper size drill bit to make sure their the same size . That's what I would check but keep with the same primers . Hope I Helped in some way .

Thank you for the help, I will keep using the BR 4's
If I did want to switch to CCI 450's would I need to workup loads again ?

No difference , this was tested before . Even with large pistol pimers & Mag primers . I like to use the best primer for the specific round being used , I would use the magnum primers in a pinch . With the same charge .

I had bad luck with Wolf SRM primers, at least with ball powder. After one year I tried some ammo I had loaded with them, fully 25-30% had a slight but very noticeable hangfire. Sure made me work on my follow-through for that match.

I use CCI 450s and BR-4s, occasionally 400s but CCI does not recommend them for AR-style rifles. According to someone who used to work at Blount/CCI the 450s and BR4s are essentially the same primer.
