Reloading .223

[ArchAngelCD]

While I prefer using CCI #41 NATO primers I have also used CCI-400, CCI-450 and Rem 7 1/2 primers and none have given me a problem. I only use standard SR primers when I can find nothing else and when loading for a bolt action .223 rifle.

thanks for all the good advise I picked up some CCI 450 today, now time to
process the LC brass and give them a try

Thanks for the answers fellas, and the thread JoJo. Hope I didn't veer it to far off topic.

This is the first Ive heard of "dimples"in primers, and Ive been hangin around here for awhile now.

What exactly do you guys mean, imprints on the primer surface that faces the firing pin? Can anyone explain?

Thanks Bexar, for the link, though I haven't checked it out yet.

not sufficiently indenting the primer to compress the anvil inside against the priming mixture, thus the primer doesn't ignite. But you still have the dimple

Ok thanks fellas. Still though, im not sure I see why this is bad. You're saying, and remember Ive shot my AR15 exactly twice so Im not very experienced with the platform, you pull the trigger, nothing goes boom, and you have a dimpled primer. Dont you just rack it outa there and move on? Forgive me if Im missing something, which I'm pretty sure I am.

Bexar, Im thinking some of my answers are in your links but I havent had much time to explore them as Ive pulled babysitting duty while my wife substitute teaches today. I have a 3 and 5 year old flicking rice krispies at the back of my head at the moment.

Not quite, the dimple is there before you pull the trigger. As the bolt travels forward to chamber the round and the rifle goes into battery the firing pin is at the rear of the bolt. When the bolt makes a sudden stop chambering the round the firing pin continues to travel forward since it is not spring loaded and bumps the primer with a very mild force. The idea being the force the firing pin strikes the primer with is not enough force to detonate the primer. Does that make sense?

I gotcha. Thanks Ron. I see what we're talking about here now. Got a chance to read some of Bexars link too, and it cleared up some of my questions.

The dimple gets there upon chambering, and the fear is that it may fire as it chambers, right? I was thinking light primer strike at the pull of the trigger or something I think...thanks.

Makes perfect sense. Pretty scary sounding,too. Im not sure I feel to good about the firing pin running into the primer before I want it to.

The firing pin dimples the primer of every rd that chambers? Im still reading Bexars link which might answer that as I get further.

Well...don't just take it...flick back!!!

Blessings to you and your family.

As Edfardos mentioned the primer can not be impacted by the firing pin out of battery for any reason unless the firing pin is broken and protruding through the "touch hole" on the bolt. In reloading the apparent preventive measure is to make sure the primer is seated BELOW flush of the cartridge case and clean your primer pocket of any latent residue before seating a new primer so either copper shavings...grit...or the bolt face doesn't set the round off out of battery. I imagine in a healthy rifle and proper primer seating you would be part of the billions upon billions of rounds fired that never were set off out of battery. I've had one slam fire (in a Garand) years ago but the bolt was closed and the Garand can not fire out of battery by receiver design either. It happened so fast I didn't realize it had happened until someone asked me about it. Seat your primers correctly and let your bullet join the other billions of rounds downrange in this noble two century on-going experiment we call FREEDOM!!!! (Can I get a Hip...Hip...Hooray!!! here. )

In case you check back, JO JO.
All of those primers you mentioned will be fine( cept the WSP, the WSR ok), if you've done everything else correctly.

To poster # 34.
If you follow what post # 22 said, that firing pin will only "run in" to your primer with the momentum of the weight of the firing pin.
If that dimple bothers you?
Do as I'd guess most of us do and make sure it goes in last when you reload it in a magazine next time.

 

[JO JO]

I don't no why I wrote WSP instead of WSR my bad, anyway I am going with the CCI 450
for now lgs has a ton in stock and they even had some TAC come in so I grabbed a pound
supply's are so hit or miss in my area happy to get what I can.
Thanks for all the above advise
