TULA primers 223/556

[Steve H]

I am lucky enough to receive 2 cases of small rifle primers, both Tula. One case is SRMag and the other is SR. Please look at the note with the primers. It claims to use the SR with extruded powder only and not "full "loads". these will be used for AR 55 abd 62 gr loads
Does this seem correct?

I have used that very primer with surplus 846, maximum loads, with outstanding results. I noted no difference between that stuff and WW/R/CCI...............that note is someone ELSE's experience and not yours, Don't trust anyone else's data, just what you verify for yourself!

I have never heard of 556 mag...........nor seen it mentioned in any reloading manuals Any idea what those primers would be used in?

I experienced consistent hang fires with these primers and military surplus, pull down powder WC844 (very similar to the commercial powder H355)


This, evidently, was a common problem with this particular combination, that I was unaware of when I purchased them.

I have used these primers with other ball powders such as Win 748 and Ramshot TAC with absolutely no problem.

I realize that these aren't the EXACT primers in your photo but my experience and the note included with yours seems to indicate the same "problem".

I will say that, if the opportunity ever presents itself again, I wouldn't hesitate to buy as much of these as I could afford.

Aside from that specific combo, they have been very good, consistent primers.

If they are like their Wolf counterparts, the 5.56 “Mag” primers are a standard mix with harder (mag) cups for 5.56 semi automatics, not a hotter “mag” primer, while the others are just standard small rifle primers

I used both extensively in 223, 223AI and small primer 6.8 with several AA and Ramshot ball powders with excellent results. I wish I had more.
They are slightly larger diameter and very useful in brass that have loose primer pockets to extend brass life.

I purchased and loaded about 30K of the standard Tula SRP with a bunch of different propellants of both types in the past. I experienced zero problems using Ar's, Mini 14's, and H&R Handi Rifles. I however did not try them in the winter or temps below 30* that I remember.

I really can't imagine a Russian primer being sensitive to the cold.

Agree completly! Its actually those wimpy little round beads of propellant that are the problem. Can't deal with the frost LOL.

The problem with ball powder is its like nitroglycerin forgets that it's nitroglycerin when it gets down around -20f and below.

I’m from Florida. At 20below I turn into a meat popsicle.

In Michigan that’s swimming weather. Just have to lift the ice off the pool first.

Coincidentally, in Florida, I melt!


As for the primers, they say 5.56 right on them…

I think that was the problem with the Wolf branded primers: Russian nomenclature.

There were 3 options for small rifle primers offerd at the time.

Standard, small rifle with IIRC, ".223" in the description: thin cup, milder/standard brisance.

Next, the primer that we're talking about in this thread, which has "5.56" in the description and a harder cup but not a higher brisance.

Finally, a true "magnum", with a thicker cup and higher brisance but, also with ".223" in the description again thus causing confusion.

*edit for spelling

 

[N555]

I read nearly everything I can get a hold of on making primers.
Military primers use harder/thicker cups.
Magnum primers contain the same amount of magic paste, but are spiked aluminum powder to make them burn hotter.
Milspec primers are both. The harder cups and the No41 mix does contain several percent aluminium.

Follow up............ I finally tested both Tula primers, the "std and the 556 M". 223 and 556 mixed head stamp cases, 27.0 grs of W748, 55gr FMJ pulled bullets. Nice sunny day temps in the 60's. No chrono. All went well and everything went BANG. No noticeable difference at all.
