Wolf SRM in .223?

[wolfman]

I know there have been issues with using SRM Russian primers in .308 palma cases, but I'm wondering how they do in small cases like .223? I've got 11K of these things. Looking to load a bunch of .223 AI with Leverevolution powder and 75 amax.

You will love them. I have shot 10s of thousands in a regular .223 with never a problem. I am now down to 6-7K of them and am waiting for something special to use them on. They were my go to primer for the 223. The Russians definitely had primers worked out.

Aren’t Wolf designed for military rifle cartridges like 223 and 7.62x 39? Should work just fine.

 

[P1ZombieKiller]

if they don't work, I will be glad to replace them 1 for 1 with the primer of your choice.

 

[searcher]

I too have shot many thousands of them in .223 A/R and bolt guns. I love them.

 

[wolfman]

glad to hear it guys. Thanks

Switched from Rem 7 1/2’s to Wolf SRM’s in an AR match rifle a few years ago and my SD dropped and accuracy was excellent.
Now using Tula 556M’s in my Dasher getting good SD’s and accuracy. Tested them against BR4’s in multiple 10 shot strings, BR4’s SD was always between 11 and 12, the Tula556M’s were all under 6.
The Tula’s have shot so well in matches, it’s my go to now...108 Berger’s, N203B and Tula 556M, jump .010

I used them when the great O shortage happened. I continued to use them until he banned imports from Russia. They worked very good in .223 with Varget at 24 to 25 grains and a 80 gr bullet. I would probably still be using them except for the ban and the fact that I have 19,000 CCI 450's to use up first.

Just make sure you seat them flush to the bottom of the primer pocket and they are AWESOME. I only have a few SRM left and they are for SPECIAL situation ammo. I have more of the Wolf LR and LP than SRM. Sure wish we could get them imported again.

I shot lots of them in my 223 Palma rifle and they perform very well with low SD’s. Wish I could still get them.

CHOOSING THE RIGHT PRIMER - A PRIMER ON PRIMERS
http://www.sksboards.com/smf/index.php?topic=56422.0

PRIMER CHART & REFERENCE GUIDE

Small Rifle Standard

CCI 400 -thin .020" cup, not recommended for AR15 use by CCI/Speer. Good for .22 Hornet, .30 Carbine. See Note 1 at the bottom of the page
CCI BR4 - match primer with a thicker .025" cup.
Federal 205 - Mil-Spec cup thickness according to Federal - okay for 5.56mm. .0225" cup thickness.
Federal 205M - same as the 205 but the match version.
Magtech PR-SR - .025" cup thickness (not much feedback yet on this new primer as to AR15 suitability but with the same cup thickness as the Rem 7 1/2 it looks good so far)
Remington 6 ½ - thin .020" cup, intended for older, lower pressure rounds Remington says do not use for the .223 Rem or other similar pressure rounds. Good for .22 Hornet, .30 Carbine.
Remington 7 ½ BR - A match or "bench rest" primer. Lyman & Nosler classify this primer as a Standard. Remington says the compound is the same as the 6 1/2 but with a thicker .025" cup.
RWS 4033
Winchester WSR - some piercing issues noted when changed from silver to brass cup. Cup thickness is a bit thinner at .021". Most say they are good to go for the AR15 despite that, probably because of the hardness of the cup. Some feel they are less resistant to higher pressures.
Wolf/Tula Small Rifle SR #KVB-223 - soft, sensitive copper cup, not recommended for AR15/military rifle use or high pressure rounds.

Small Rifle Magnum

CCI 450 - same thicker .025" cup as the BR4 and #41.
CCI #41 - commercial version of the fully-qualified DOD primer for use in U.S. military ammo. With this primer there is more 'distance' between the tip of the anvil and the bottom of the cup than with other CCI SR primers. .025" thick cup. Same primer mix as CCI 450.
Remington 7 ½ BR - A match or "bench rest" primer. Hornady, Handloads.com, and Chuck Hawks classify this primer as a Magnum, differing from other sources that classify it as a Standard. .025" cup thickness.
Wolf/Tula Small Rifle Magnum SRM - hard, less sensitive brass cup intended for AR15/military rifle and high pressure rounds - #KVВ-5,56M.
Wolf/Tula Small Rifle 223 SR223 - #KVB-223M "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."

NOTE 1: According to Speer/CCI Technical Services - Both the CCI 550 Small Pistol Magnum and CCI 400 Small Rifle primers are identical in size. Both primers use the same cup metal and share the same cup thickness. Both primers use the same primer compound formula and same amount of primer compound. They can be used interchangeably.

I wish I could get them also. I use CCI 450's since the Wolf is not available. I did get my hands on 30,000 Tula LRMP from the last stock at a vendor in the U.S. before they were gone.

 

[JAlfred]

Great with extruded powders, with ball I stick with Rem 7 1/2 or 450s.

 

[stacy]

SEND ME A COUPLE THOUSAND I'LL SHOOT THEM AND LET YOU KNOW IF THERE A PROBLEM !!!!!!!!

Why? Would you please expand on this?
Thanks

Sure,
I have had a few issues with Wolf SRM and ignition with ball powders. Though labeled "magnum", they are not different from their standard primers other than cup thickness.

http://bulletin.accurateshooter.com/2008/02/wideners-has-russian-small-rifle-magnum-primers/

The other issue is the "sponge worthy" problem. They are my choice for accuracy loads but they cannot be replaced, so why waste them on loads that aren't your very best. Ball powders don't generally give best accuracy for me.

I do not use them outside of 223. I have small prime 6.5 CM brass but have avoided trying any worrying they may not have enough juice for ignition in the bigger case.

I believe that's why the KVB-223M / SR223 model was introduced. There had been complaints the SRM / KVB-5,56M didn't always ignite some newer ball types well giving increased ES and SD values, or worse. (I have a suspicion this may refer to Hodgdon CFE-223 which I've found harder to ignite than other, older ball types.)

TAC was the problem child in my case.

 

[mousegunner]

I have Tulas which are supposed to be almost the same, no problems for me. I'm down to my last 4K, wish I had bought more.

I use them for H335 and IMR 4895.

 

[Longtrain]

FWIW, as long as ball powder issues came up, I have had no problems using KVB-556M’s and AA2460 ball powder in my 223 and 223AI. I have a supply of TAC, but haven’t used it lately, it was used with 7 1/2’s.
I did have FTF problems using Tula or Wolf LR primers in my F-TR 308 a few years ago. May have been just that batch, but had at least 2 or 3 rounds in a match that didn’t light even with a 2nd primer hit. Sometimes it would go on the second hit. Switched primers, no problems.
