Per Widener's nomenclature;

QQQSR KVB-223 Small Rifle Primer

QQQSR223 KVB-223M Small Rifle Primer

QQQSRM KVB-556M Small Rifle Magnum Primer (for use in 5.56 loads)

Per Widener's nomenclature;

QQQSR KVB-223 Small Rifle Primer = Standard primer

QQQSR223 KVB-223M Small Rifle Primer = Harder cup and hotter

QQQSRM KVB-556M Small Rifle Magnum Primer (for use in 5.56 loads) = Same as standard but with a harder cup

The consensus is get the QQQSR223 - thats what I have on order from Wideners previous batch.

Hope this helps.

SR-Standard Primer

SRM-Harder Cup, Hotter primer; the magnum primers are hotter than the standard primers and the .223 primers

SR 223/5.56- standard primer, harder cup; the .223 primer may or may not be hotter than a standard primer but for sure not as hot as the magnum primer, they just took a std SR primer and gave it a harder cup and call it a .223 primer, it has been proven to be slower than the SRM primers so I bet it's the same as the std SR primer.

Yep, the Wolf 5.56's are standard power primers with a hard cup. I've found them to be very consistent in both 6.8 and 5.56 loads.

An additional benefit is they tend to be a snug fit in the pocket, which is a good thing with some brands of brass.

 

[Test_User]

Thru all the accuracy testing and SD ES testing I found the 5.56 primers to be the most effective. This has also been confirmed by numerous people since I first starting telling people about the Wolf primers on here. It has the standard level charge but a harder brass cup. What ever you do do not use the standard small rifle primers as they use a softer cup that you will likely pierce with the AR firing pin setup.

Thanks everyone. I missed a chance to pick up SR and SP primers as Wideners is now out of stock on small pistol. It looks though like they are starting to get Wolf in on a regular basis. Next time they have both, I'll pick some up.

Thanks

Confusion over Wolf primers ?

Guys, I'm still a little confused about the Wolf primers, so please bear with me as I'm sincerely asking for clarification about the new Wolf primmer..
From Wideners website: SMALL RIFLE 223 (part # QQQSR223) NEW NEW This is the newest primer available in the Wolf line. It is ever so slightly hotter than the small rifle magnum primer and it comes with a brass colored thick cup. This primer can be used in place of the SRM primer or used when a different powder is used that is hard to ignite.

A post from Widerners on ARFCOM: Originally Posted By team_oops:

I am wondering if I should have purchased QQQSR223 instead of QQQSRM?

And their response : Originally Posted By WRSSI:

The part # QQQSR223 Is a FULL BLOWN MAGNUM PRIMER and should only be used on loads that call for the use of a Magnum Primer. This can be confusing because of the packaging, the True HOT magnum Primers say 223 on the inner packaging or KVB-223M on the outter 5k case, and the 5.56 primers say Small Rifle Magnum on the inner packaging or KVB-5.56 on the outer 5k case. We had no control over what the packaging says, only in how it is worded on the advertising..

When you order the QQQSR223 from Wideners the item # in your cart is--QQQSR223-KVB223M------So this tells me that these primers must be hotter, as they say it's FULL BLOWN MAGNUM PRIMER..Am I reading too much into this ? Is this primer suitable for 6.8 & 223 ? Just use it and start off with reduced loads or don't worry about ? Any and all advice will be greatly appreciated..

SMALL RIFLE PRIMER (part # QQQSR) - Used as a standard small rifle primer. Perfect for the 30 carbine and 223 standard loads. Many people use this primer in bench and other loads for the 223. This primer is a copper colored primer.

SMALL RIFLE MAGNUM PRIMER (part# QQQSRM) - This is the primer we had before for use in the 5.56 loads and hot 223 loads. A thick cup for the higher pressure. We sold a lot of these primers earlier this year. The new lot is brass colored instead of nickel.

The SMALL RIFLE MAGNUM PRIMER (part# QQQSRM) or the SMALL RIFLE 223 (part # QQQSR223) NEW NEW are the better choices. I didn't notice much of a difference.

What you say makes sense to me, because I trust your testing results, it appeared Wideners was warning folks that the packing description didn't match the intended content of the item..And I'm NOT picking on Wideners because I happen to use them and they have always provided good service.. It's just been one of those weeks, ever have one ?
Thanks again,

I have SSA LR brass. What's the top 2 primers for 6.8? I load 90 gr TNT's, 110 PH, and 130 Sierras.

 

[Bubba FAL]

I use CCI #34 primers for all military rifle cartridges with a large primer (6.8, 7.62x39, .308, .30-06, 7.92, etc.).

These have a harder cup for protection against slam fires when fired in autoloaders with floating firing pins.
