I am having a small problem. I am finding a variation in the thickness of the base of the brass(the rim that slips into the shellholder) and some don't slip in to the shellholder without force, they bind because they are thicker.

This problem continues on to the CRF bolt claw of my Mauser - most feed great but some are thicker and the bolt claw has problems slipping over the rim.

I can force the brass into the shellholders and I can slam the bolt forward and the shell loads but I think they all should work the same - smooth.

The brass I have been using are S&B as well as Prvi Partizan. It is probably 5% of the brass or less that have the problem.

I have not had this problem with any other caliber brass, but all my other brass is either Winchester or Remington.

Anyone else have this problem? Is it my brass brand choice? What brand of brass would you suggest?

Thanks in advance for the feedback.

I don't load the 9.3x62, but I occasionally get similar problems with various sorts of European brass - mostly RWS, which I see quite a bit of. The problems I have experienced, have usually been a somewhat oversize case diameter, and I have mostly been able to resolve it by using a shell holder for the 6.5x55 - which is slightly larger than the standard .30-06, 9.3x62 etc.

If you want to try different cases, you are more or less limited to European brass. I would personally try (in order of preference): Lapua, RWS and Norma. Lapua surprisingly still sells 9.3x62 brass, although they have stopped making bestsellers like the .270 Win. I'd try the Lapua, and if it works well, I'd quickly buy 4-500 cases to be on the safe side. I believe Bruno's may still have some available.

I have this issue with Graf brass in my 9.3x62. Like MHO says above, using the shellholder for the 6.5x55 (or the .257 Roberts and 7x57) will take care of it. I use the one for my 7x57 Ackley imp, which is the same as the 7x57. For the Lapua brass, the RCBS #3 works fine.

I had the same proiblem with Graf 9.3x62 brass. I don't care how cheap their brass is I'm never buying their crap again.

I can always use a bigger shellholder - I understand, but like I said - if it won't fit the shellholder without forcing, it won't fit in the bolt claw without forcing.

I guess I should go to a better brass. I'll look at Lapua and Norma.

Thanks

I use the Graf's brass and have not ran into this problem. Maybe they had a problem with a particular batch.

FWIW, I used Graf 9.3x62 brass with complete satisfaction and the #3 shell holder fit perfectly. But, 7x57 brass required a shell holder for .220 swift I would have returned it but it worked after a fashion and I was hard up for brass. It shoots fine, just gotta use the proper case holder. I did call Graf's and they said it was an issue with that lot of brass.

The head of a 9.3x62 case is a few thousandths larger than the heads of '06-based cartridge cases. That's why people warn against forming 9.3x62 brass from '06-based brass - even though it works, technically the '06-based brass is too small. Proper 9.3x62 brass may bind in an '06 shellholder or in the extractor if your rifle was built to fire an '06-based round before you converted it.

I fixed the problem by using a 6.5x55 shellholder. My CZ 550 didn't have the problem since it was always a 9.3x62.

Either way, it's frustrating as hell.

I think some of you are missing the point.

If some of the brass will not fit the correct shell holder, then they also WON'T fit in the claw on the bolt.

Hence they will not feed correctly or at all.

My question was more: Have you ever had this problem? and What brass would you recommend?

Now I just throw out the brass that won't go in the correct shell holder.
