Wolf SRM in .223?

[jelenko]

Sadly, I have no more Tula or Wolf SRM primers

When I first started using them, I did have a few FTF's. Over in the National Match Competition forum, a couple people mentioned that Tula/Wolf are [were] sensitive to being fully seated. I had no more FTF's after modifying my Dillon 550B to increase the range on seating depth. Hand priming cases also worked.

When i was shooting the .223 in mid and long range.. the Wolf/Tula SRM primer was all i used..

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.

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.

Thank you for your reply.

We have them back again in the UK under the Russian brand name (Murom). For years, we got them here as PMC primers before PMC dropped out of the sporting ammunition and components business. Back then, they were regarded as low price, but equally low quality - the first true, the second very much untrue. (The Tula/Wolf brands have never been used on primers in Europe AFAIK, but we do see Russian ammunition so named.) I worked for the UK PMC distributor for a while and am still using up the last hundreds out of cases of these Russian primers I bought with an employee discount some 15 years ago. I only wish I'd bought even more than I did.

One very late / belated finding was that the 5,000-ct carton of LRMs I'd acquired didn't turn out be the overly 'hot' number I expected and is not only 'mild' compared to true 'hot' magnums like the F215M, but is milder than most standard or BR LR models. I used it in a 7mm Shehane for a few seasons and now in one of my 7mm-08 loads very happily with powders that most definitely do not need true 'Magnums'. That's the KVB-7M in Murom nomenclature.

FWIW, I used Murom / PMC SRMs in all my match 223 Rem F/TR ammunition with Viht N150/550, H. VarGet and (most often) Re15 under 90s for long-range. I got considerably better results than from CCI-450/BR-4 or F205Ms. I like the later KVB-223M / SR 223 in 308 Win 'Palma' brass F/TR loads, but have yet to try them in 223.

Another SR primer I liked for 223 was the Rem 7 1/2BR, but it has a slightly softer cup IMO than the Russian SRM. I've long used the 7 1/2BR in smaller cartridges and like it a lot. As with the Russians, we had a distributor here who used to sell them at what is now a fantastic bargain price and I'm still living off my purchases of years ago. Long gone here now at any price, I'm sorry to say!

A final suggestion is a make and model we don't see much of in the UK, but may be more common in the US for all I know - the Brazilian CBC Magtech 7 1/2. It's another 'mild' primer ideal for smaller cartridges, but as with the Remington BR has a bit 'softer' cup than the Russian 'magnums'. I use it in 6BR and get excellent results from case-full loads of Viht N150 and 107s.

I use them for everything from 5.56 to 6.5x47L. Never had any ignition problems.
