I know nothing about the Tula small rifle primers other than these are designed for 223 rounds; the KVB223M is the NATO spec if I recall correctly.

How are these? For my 308 I use the 7.62 Tula primers and they are awesome. Any reviews on these, and will these work well with ball powder like AA2230 and/or small extruded like Benchmark?

I plan to use these in a 16" Stag and 16" KAC carbine.

Thanks

I use the wolf 223 primers and aa2230. I have had a couple no bangs out of about 500 rounds. Not sure what the cause was. The primers seem a bit tight when seating, but im a new reloader so I don't have much to compare it to yet. I got them for $14 /1000 so no real complaints.

I have some of these primers and I have used a few hundred so far. No issues so far that I can find. But I have only used them in cartridges other than 223.

The problem I have with TULA primers is the anvils fall out in handling.

No issues in .223 or with their pistol primers.

Fired 1k so far.

For AR15 you want either the KVB223M or the KVB556M both of these have a thicker primer cup than the KVB223. The KVB223M was marketed after some reported difficulty lighting ball powders in 223/556 w/ the KVB556M.

So:

KVB223M or KVB556M for stick powders in AR15
KVB223M for ball powders in AR15

KVB223 - low pressure loads only in 223 or for other low pressure small rifle loads (22 Hornet, etc.)

The main issue with kvb223 is ignighting h335. Had it happen twice. TAC ingnights without issues and very consistent. I get better SDs with them vs CCIs

As mentioned kvb223m is hotter and kvb556 is just a thicker cup.

Never had a slam fire with kvb223, or pierced primers.

So the kvb556 is NOT a magnum primer, just a thicker cup?

If yes, I'll look for some. Some Service Rifle loads I'm working

up are too hot for a magnum, but thinner cup like CCI 400

is not ideal.

Their labeling is confusing, I've been using the kvb556 primers with wc844 and haven't run into any issues. Shot a 50 round string that had a SD of only 14 loaded warm with 844 and Hornady 55gr FMJBT's. 10 round groups of around 1.5" at 100yd with chrome lined barrels and me limiting accuracy
