If any of you load for this caliber, you've no doubt found it hard to find brass. Graf and Sons has unprimed Prvi Partizan for 46 bucks a hundred with free shipping. I just received 500 and it is nice brass. Also, the case necks look to be annealed on it already, so it should last a long time with my cast bullet loads.

another option is to buy the ppu brass with a primer, bullet and powder in it already. only $26 more per hundred to get em loaded already, aim has a good bit of it for $14/box
^^^^^^
I do the same for my lower volume/obsolete calibers. 7.62x54R, 8mm, 6.5x55, 303 Brit. I have never had a complaint about Prvi brass. In fact, 5 loads later at 2300-2400fps(174gr) in my .303 the cases are still holding on through initial firing w/ o-ring and neck sizing there on.
All case necks are annealed as one of the final steps in bottleneck case manufacture. Some manufacturers polish it off, others don't bother to. Personally I don't mind either way but if it keeps the cost of Prvi where it's at then so be it!
Good luck with your new brass. I'm pretty sure that the o-ring method will help keep case head stretch minimized in 54R as well if you're shooting a Mosin or other bolt action milsurp as long as the cast bullet loads generate enough pressure to form the case.

Hey 119er, I've been loading the Mosins with cast bullets for years, but I have never heard about the O ring method. What is it buddy? You've perked my ears up now! The brass for the 7.62x54 last a long time as is, but I have to know what that is! Are you using it to take up some of the excessive headspace some of these puppies have?
That could be a good possibility. Its a common methed for enfields in 303. None of mine are that way except one, I bought a really nice enfield with a new carbine barrel, redfield peep and lyman front sight. I literally paid next to nothing for it. The action is smooth and tight, the metal is in really nice shape with a lot of blue, and the barrel is brand new but whoever put it on never had it headspaced. So...That's my next project. I used an .08 thousandths o-ring to try it an it shot perfectly. Without it it tends to be challenging to pull the bolt back after firing.

Just a note, all manufacturers have to anneal the brass during the process of forming the cases. The American manufacturers tumble the brass afterwards to shine them up before they sell them. The exception to the rule is military brass.
I never knew they did that to all brass. I know I never do it either, even after the necks harden after a lot of firing, but I have always had intentions to do it. By me, getting brass was just as easy as bending over and picking it up at one of the ranges or gravel pits where people shoot. But, now, as we all know, it's definitely not that easy in most places any more. A guy has to take better care of the brass one has.
It's nice to see oddball brass hitting the market again. I think it's a sign that maybe things are starting to let up a bit. Just on the other side of my land there is a county range and lately there has been a lot more shooting than there was 6 months ago.... (wish they'd leave their brass!)

There are excellent tools available to the handloader for annealing. Too, one can buy a little tempilaq and a deep socket large enough to accommodate his brass, a Bernzomatic torch and anneal his cases himself as another step in case prep.
Hornady used to sell a kit for this, but it has been discontinued.

I love prvi brass, its all I use for every day obsolete rifle stuff.
Hey Duckdog I've been away for a bit. That is exactly what it does. The O-ring keeps the case head against the bolt face to ensure that brass stretches forward. If there is a generous headspace the case body swells to the chamber under the pressure of combustion thereby "gripping" the chamber walls. The head of the case and ~1/4" above it do not expand because of the extra wall thickness in that area. The non-expanded portion will then be stretched back to meet the bolt face. This thins the brass at the area where case expansion begins and can lead to case head separations if ignored; especially when full length sizing. From the stretched area forward the case behaves like you would expect a rimless cartridge to.
I used to be able to find an animation of what is happening but can't locate it now.
I do believe that the next time I am doing the o-ring forming I will remove the extractor. I don't like watching it pop over and try to compress the o-ring. Just looks bad to me.

The Prvi brass is real nice, though the first time I loaded the 54rs I was a bit confused as to why the primer sat so far in the pocket. But sufficed to say that they performed flawlessly in my PSL out to 600 meters. Even took a chuck at 200 meters. The stars aligned that day and the steel never stopped ringing.
I also use Prvi on my 30-06 for long range shooting. Never a problem with it. I too recieved mine from Graf's. Thanks Kirsten

I noticed that too, my primers always seated VERY deep in Prvi x54r brass.
