223 Primers

CCI 450 There cheaper than the 41 and still seem plenty hard enough to run in the AR.

I've run a bunch of the 400s in my AR, no problems and they cost less.

450 and #41 use the same cup according to cci. Good to go in floating floating firing pin applications. I got a few doubles when using cci400.

Just picked up 2k of CCI 400s at the local shop for $34.95/1,000. I've had no problems with CCI and, like has been said here before, they're cheaper. Be safe, and have fun.

+1 on the CCI 400s. I've had good luck with them. They are easy to find and have given me no problems in the last 1600 rounds

Tritto on the CCI 400.

I use in this order:
CCI#41
CCI450
Rem 7 1/2
CCI400
WSRP

Just a note, the CCI#41 primers use a compound which is less sensitive than "normal" primers, bit standard and magnum.

CCI 41 or CCI 450. Nothing else.

No issues with CCI 400's in any of my AR's. Never once a double or slam fire.

I've reloaded and shot several thousand rounds of .223 in my AR loaded with CCI 400 Primers. Never an issue.

This ^^^^^^

I decided to use CCI 450 primers when I began loading for my AR. They are harder than the 400 and I just felt it might be safer without spending the extra money for their #41. I have never had a problem. I do have friends that use 400s and have never had any issues.

I use CCI 400 primers as well.

Remington SRBR for me.

If your buying online,Powder Valley has Tula.

400's are fine with me. Like a lot of guys, thousands without a problem.
And yes, I have had a slam-fire in an AR, but not with CCI primers.

cci 400

I have used 2000 CCi 400s in 223 and never had a problem either.

Forgot, I've also used a lot of WSRP. No problems there either.

used about 6k CCI400... not a single issue

Most people don't have problems using CCI 400 primers and when they do, probably 75% are caused by not seating them deep enough. I've seen a slamfire that occurred with commercial .223 ammo and I don't really want to experience one myself so I use 41's and 34's just for that extra measure of protection which they will provide. My LGS sells all CCI primers for the same price (too much) anyway.

Although I have never experienced a slam fire, I want to avoid them as best as I can. I am often able to find Remington 7-1/2. Sometimes CCI 450 and once in a blue moon, I'll find the CCI 41.

Ever wonder which primers Winchester uses in their 223 ammunition? I would imagine their srp primers, but I have no idea.

I have used CCI 400, CCI 450, CCI BR4, Wolf(Tula) KVB223, Remington 71/2, Winchester WSR and Federal 205 ... never had any problems with any slam fires or other ...

I've read that everybody's .223 is primed with SRP's and 5.56 is primed with NATO primers. I don't know for sure but it makes sense to me.

I should add that another reason I use CCI 450 is I also load for 6.5 Grendel and it seems to like the magnum primers. Its just easer to use the same primer for both.

Only slam fire problems I have ever had was with one box of factory 6.5 which I had a slam fire and several doubles. Never had a slam fire in my 5.56.
