I did search but didn't find much related to Murom Small Rifle boxer Russian primers. Since it's one of the few primers that are regularly available to me in my area, I would like some feedback on them.

If they work well in precision loads great, if they work well in my bulk 5.56 loads that will work as well. I can save the hard to find US primers for precision work and use these for my bulk 5.56.

Thanks

Murom is the name of the plant that also makes the Tula and Wolf branded primers.

My experience tells me these are really good primers. Use them if you can get them in any application.

I ordered 5000, they are located In Pompano Beach which is just north of my location. I have a buddy that orders from them often, this will be my first time. Should be here in a couple of days, fuel for the drive is more than the shipping.

Here the link if you want to order some:

Just got my primers order in from Cheapest Ammo.
They are the KVB-223, not the competition primers. They are not the CT-KVB223.

BTW: I encountered one hang fire out of 50 6mm creedmoor round I fired on Saturday with these primers.

The Win SR and CCI 400 continue to shoot well.

I'm trying some CCI 450s this weekend if I can make it to the range.

@Leadrain22

Did you swap these primers into a known load?

If so, did you get any velocity info to see how the same load, with only a new primer, fared? Accuracy worse, the same, better?

Thanks for making the leap and keeping the rest of us posted. I've got some friends who got into reloading at the worst possible time and I've forwarded them a few in-stock notifications for these while they try to build up their stockpile.

    Russian-made primers fit very tightly in the case. You need to make absolutely sure they're all the way in.

    I've fired close to 7000 of their small pistol primers with zero malfunctions, but I use the priming session as a grip workout too.

    Tried the following primers in Lapua SRP and 42.9 gr of Stabal 6.5 behind some ELD-Xs @ 3140 fps

    Rem Buchrest - Hang fire
    Murom KVB-223 - Hang fire
    WIN Sr - worked fine
    CCI 400 - worked fine

    Going to try some CCI 450 next.

    Other than the CCI 400, I haven't shoot the others through a chrono Didn't see any reason to if I'm getting hang fires.

    But it's simple enough to load a string of each and shoot them through the chrono. I might do it next time around.

    They shot well, but I was getting vertical dispersion. Likely some small seating depth or powder tweak would correct.

    I'm going to load some 5.56/223 with these Murom primers. I suspect they'll work well enough, if they do I'll use them exclusively for my 5.56 bulk range ammo.
    They will be used in something for sure.
