Russion primers

[blackthorn]

I got 1000 primers (Russian made) as part of a deal at the local gun show. The box is marked KVB-223M and it has a green circle with a red M inside. There is a vertical green line inside the circle that runs down through the M. There is an R inside a circle just to the right of the green circle and slightly above. Inside the carton are flat 100 piece primer "flats. The paper cover on these says: MUROM apparatus producing plant made in Russia. Anyone know anything about these? Any good? I want to use them in my Weatherby Vanguard 223. Thanks!

Wolf / Tulammo KVB-223M magnum primers are for NATO spec ammo for Semi-Auto's. These will be mil spec in sensitivity and should minimize the slamfire hazard. Haven't had any issues with using them, work just fine. A lot of high master highpower and long range precision shooters swear by the Wolf. The Magnum primers are used for harder to ignite powders like heavily coated ball powders such as H335 . I will say Wolf tends to be slightly larger than some US primers so they fit snugly in primer pockets that have seen a few max loads already.

"We stock the KVB-223 and the KVB-556M, The 223 has a copper cup, and is for use in Bolt gun applications, the 556M Has a harder cup to aid in the prevention of slam firing, similar to what you have in CCI's Standard and Military primers. With Wolf's Standard being softer
There is a slight temperature difference between the 223 and 556 but nothing like the difference between the 223 and the 223M. The 223M is a true full blown Magnum primer."

The anvils on Russian primers are flush not proud like US primers so they need to be seated to the bottom of the pocket or you will get FTF's. With the Russian primers "magnum" is always a thicker cup but it may or may not be hotter.

I use them in pistol and revolver loads they work ok for me and that factory in Russia has been making primers since the early 1940s.

Thanks guys! They were basically a freebee to sweeten the deal on the 50 handloaded (to be broken down) Weatherby cartridges (in a plastic 50 round box) that I was looking at. I know the guy that loaded them and I trust him BUT I know he likes hot loads and I make it a point to never shoot someone else's reloads. Sure enough when I checked the manual(s) he was a full 5 grains over maximum (average). When I pulled them down, the charges were exactly what he said they were. Needless to say they are not anymore.

I bought 5M of the Tula Large Pistol primers. They have worked very well for me. The ones I have measured average .0003 larger in diameter, as compared to a CCI LPP. I bought them because I had heard they are a little larger and I like my primers on the "tight" side.. I've gone through, maybe 2000 so far and no misfires.

You bought 5 million primers!!!????

[sdcitizen]

I'm pretty sure that M is the abbreviation for thousand. Roman numerals.

[tomme boy]

Not where I come from. That means 5 Meg or 5M = 5 million

This may have something to do with the ~1% failure rate I had when I tried the Wolf primers. I had also just uniformed all the pockets using the redding tool.
