Which primer?

Post by JoJo » 26 Jan 2013, 09:20

Before you scold me: I did search!

I have three brands of small rifle primers on the shelf and I know I need to standardize on just one. My only reloads are 5.7 and 223. If necessary, I will keep different primers for the two calibers.

Suggestions? :ponder:

What does your manual say for the two calibers?

I only listen to people with real experience with reloading! I think you fit into that group somewhere. I have no manual for reloading because I do not experiment. The info from this forum is worth a lot more than any manual. :D :D :D :D :D :D

I do reload but I use the manual for every load other than 5.7 (I too use the forum for that :D).
I can tell you that I have used CCI 400, Winchester Small Rifle, & Remington 6.5 primers for the 5.7.
For .223, my Lyman manual has Remington 7.5 primers listed & the Speer manual shows CCI 400 & 450.

That Rem 7.5 primer has also been successfully used by some people on here for their 5.7 loads. I have no doubt that other manuals will show other primers as well but that is all I have.

You can never have enough manuals. I have hard copies of every single loading manual in their up to date form. I also have traded for with members here and from other sources dozens of older manuals. I have 1st additions of all the current well known manuals. They are a treasure trove of information and an endless inspiration for me to come up with new loads. I have dozens of loads I have created with custom bullets we have not been able to bring to market inspired from what I have come across in old manuals. There are rounds that where at there time were cutting edge, stretching the boundaries kinds of rounds that went nowhere and then where dropped from all subsequent manuals.

The 5.7x28 is no where near as new as some folks think. It's decades older, well it's rimmed inspiration is.

GONRA knows SMALL RIFLE MAGNUM primers (CCI Military, Remington 7 1/2)
(thicker cup, withstand higher chamber pressure, are slam fire resistant)
are what you want for .223 reloading.
Just Don't Doit With Small Rifle Primers! DON'T EVEN THINK ABOUT IT!

SMALL RIFLE (Wincheter WSR, CCI 400) are fine for 5.7x28FN .
BUT - others reloaders seem to be satisfied with SMALL PISTOL primers. ???

Remember that SMALL PISTOL MAGNUM primers
are usually IDENTICAL with the same manufacturer's SMALL RIFLE primers.
(This is NOT "Urban Legend BS".
Looong ago, eyeballed manufacturer's data sheet / manufacturing print
in their ammo factory, that listed their INTERNAL MANUFACTURING PRODUCT NR.
Print continued on - mentioned USAGE as SMALL PISTOL MAGNJM and SMALL RIFLE.
Maybe I have copy of the print in my huge Primer FIles. Who nos?

Yea, WHO CARES???)

Jojo,
As odd as this may sound, I'd take a look locally or at least from your major supplier and see what's available through your normal channels. Choose the primer that you can get reliably and work a load up for that. I, like a lot of other shooters, keep a reasonable supply on hand, and I try to buy in quantity for both consistency and price. Sometimes one type is available over another. Keep your loading data complete and you can switch without too much effort. Buy in reasonable quantity and you won't have to switch much at all.

Just my two cents worth.

Anyone utilize Federal Small Rifle Match Primers for 5.7x28 loads? These primers are all I've found in my area.

I would stick with what GONRA said about the primers. I also only load 223 and the 5.7 and I tried CCI400 and WSR for both. I found they only work in 223 with light loads. At normal load levels I started seeing CCI400 primers flattening earlier then with CCI41's and REM 7 1/2. I didn't have any pierced primers but have been told I was lucky. I now use CCI41 or REM 7 1/2 for my AR depending on what is available. And I use CCI400 and WSR for my 5.7 also depending on what is available.

Thanks to you all especially Gonra! Looks like I am ok with the 5.7 primers but I have to find some for 223. :)

I use Remington 6 1/2 or 5 1/2. Seem to be identical as stated here. Lyman calls for 7 1/2 but that's overkill and more $$$. WWSR also work fine. I use True Blue powder. Loading 40BT, 50SPSX and 53 VMax subsonic.
