I'm new to reloading and i was wondering if there is much of a difference in "TULAMMO SMALL RIFLE PRIMERS (KVB223)" or "TULAMMO SMALL RIFLE MAGNUM PRIMERS (KVB556M)"
They are the same price, and was planning on using them for 5.56 and 6.8spc.
Thanks.

Magnum primers are for magnum loads.

They burn hotter than your regular SR primers.If for some reason you're going to use a SR-M primer in your 223REM, be aware that you NEED to rework your powder charge, and lower the maximum charge (and be aware of pressure signs).

Uhhh. I didn't say that... Don't come lookin for me if you get a Kaboom. Honestly, I see no reason to be mixing a SR-M primer into a cartridge that uses a SR.

You need to contact Tula and ask them. If they are the same primers as Wolf primers, but just under a different name, the only difference is the hardness of the cup. Wolf only marketed their "magnum" primers the way they did in order to appeal to the AR15 reloader market, and they simply did so with harder cups so they wouldn't slamfire in the AR rifle.

Are you sure about that? Because Wolf/Tula have 3 kinds of SR primers:

SR 223 Primer (hard cup for anti-slam fire)
SR Magnum Primer (magnum loads)
SR Primer (regular)

Just don't mix them with H335. The recent production primers from that plant aren't running good with that powder.

I use the hottest 5.56 mag primers in every load and it makes no difference in max charge over a std primer, so work up looking for the most accurate load and don't worry about the primer, a primer can not cause a kaboom.

Contact them and ask. Wolf started with just "small rifle", then they added "small rifle magnum" and they were the ones that heavily advertised them as being the same with only harder cups, and then they introduced the "223 primer", because no other company had ever sold "magnum" primers the way they were and they were causing confusion. I am willing to bet that the 223 and magnum primers are exactly the same. Just relabeled.

Wolf at one time was making only SR regular and SR Magnum, H53EXPERT is entirely correct. Wolf SR Magnum OF PAST was made with a harder cup than their regular SP primers and not like American SR magnums which meant extra zippy. Wolf SR Magnum OF PAST was equilalent to CCI #41. This info was posted on their website as such IN THE PAST. Now it is not and states 3 different:

Small Rifle, Small Rifle - .223 Rem, Small Rifle Magnum

Maybe they are trying to be consistent like American companies but for many years Wolf SR Magnum was sold as just having a harder cup. Oh their naming method was/is stupid and leads to contradiction like this on the web. Silly Russians should have named it right in the first place.

This is the information that is still posted on the Widener's website for Wolf primers:

Wolf small rifle primers are now available in types.

SMALL RIFLE PRIMER (part # QQQSR) - Used as a standard small rifle primer. Perfect for the 30 carbine and 223 standard loads. Many people use this primer in bench and other loads for the 223. This primer is a copper colored primer.

SMALL RIFLE MAGNUM PRIMER (part# QQQSRM) - This is the primer we had before for use in the 5.56 loads and hot 223 loads. A thick cup for the higher pressure. We sold a lot of these primers earlier this year. The new lot is brass colored instead of nickel.

SMALL RIFLE 223 (part # QQQSR223) NEW NEW This is the newest primer available in the Wolf line. It is ever so slightly hotter than the small rifle magnum primer and it comes with a brass colored thick cup. This primer can be used in place of the SRM primer or used when a different powder is used that is hard to ignite.
