What primer do y'all use for your .223 loads?

I have been reloading for 30 years and generally follow Speer's advice concerning primer selection. But I only started loading for .223 a year ago. Speer manuals call for magnum primers with all ball powder loads. Nosler manuals show standard primers for all .223 loads. The Lyman manual I have calls for magnum primers only for a few of the loads, and the Hodgdon manual shows standard primers for all loads.

Up to this point the load I like best is 26 grains of H335, a 53 grain TSX, and a CCI 450 (small rifle magnum). I am going to try this same load with a Federal small rifle primer.

So, what primer do you tend to use?

CCI400

CCI BR4

CCi BR4 or Rem 71/2. I've never had a problem with CCi SR primers but the bench rest primers give you a warm, fuzzy feeling that worth the few extra bucks.
FWIW, I use H335 and have never had ignition problems with standard primers.

Remington #7 1/2 Bench Rest work for me in the 40X and Semi auto loads.

IMO you never need to use a magnum primer in a 223.
In my bolt action rifles I use Fed 205's in my semi-autos I use Rem7 1/2

CCI BR4,Fed 205

CCI #450 with H-335

Remy bench rest

Use the one you find now a days

CCI 450

Started with limmited supply of rem 7-1/2 they ran out, bought the CCI model tried them in loads I worked up with the rems, a flawless transision and never looked back since.

Glad I bought the amount I did four years ago too, for some reason they are not so common right now....

I have not used any ball powders, but use my .223 alot in the winter months and have had 0 issues in the 'go-bang' dept. Don't know if it really makes any differents, Bad or problematic primers for me have been so rare, I almost believe that a bad primer dosn't exists.... Any primer size or application

Powder and bullet seat depth seem to be more problematic than primers in load trial and error....

Ive used the CCI400 and the cheap Magtech primers and they have both worked fine.

I have used about everything available, but my preference is the CCI 450. I load for 3 AR 15s, and prefer the slightly thicker cups as an extra measure of safety. I do tend to get lower shot to shot variation with them also.

Living up here...what he says!

26 H-414 is also my go to load with 55gn Sierra's
Tried reg & mag primers & never found an ounce of difference.

+3 or 4 ... Used these in a .223 hand load that would consistently shoot in the .3's out of a factory HB Savage that I wish I still had....

Prefer the RP 7 1/2, have used CCI-400, 450, BR-4, Win SR, Fed 205 and most recently Wolf 223. Have had good results with all of them. Would use the Rem 7 1/2 if available, but have a good stock of Wolf 223. Just glad to have a good supply on hand these days.

i have been using cci400 and 450 mag i have seen that the cups on the magnum primers are harder has anyone noticed this to
