Hello,

I've picked up a small quantity (less than 2K) 9MM cases that I'd like to get roll-sized. If any shooters have a roll-sizer and would be amenable to running my brass through, let's get together to figure out a cost for your kind service.

Thanks,
Chase

It's unclear whether they offer this as a service for your brass, or if they process their brass this way.

Interesting - I'd not heard of roll sizing previously. Looked at the Wolf Bullets site and that led me to the equipment manufacturer:-

Thanks fellows- I found a shooter who could help. 

I like the idea of this sort of preprocessing (which I sort of do for my 45 brass) because it will feed through the reloader smoother, and, in theory, keep powder drop variance low. 

But mostly, it's of benefit to my elbow and shoulder when running the press. A little bit of case lube and sized brass is the way to go.

What does a "roll resize" do that a resizing die does not do?
What makes it easier to do, for the operator?
Is it working on the diameter of the brass, or the length?

Never heard of this. before.  Just curious.

Glocks and some other ‘wondernines” have large feed ramps that extend into the chamber.  Cases fired in these pistols have a tendency to bulge at the lower 1/3 of the cases.  Glock 40s are notorious.

Hmm, if they do, which I assume is when the gun fires, does this get corrected by a good resizing die?  Maybe that's why reloading those cases takes extra effort?

They bulge below the area touched by the sizing dies.

Mike, look at the links above and you will see some diagrams that explain how it works. Yes, as Wobbley has said, some guns allow the brass to bulge or otherwise deform at the very bottom of the case just above the rim. A conventional sizing die cannot reach down so far (because the case is held in the shell holder in the loading press when you are resizing).

I often see once fired 9mm brass in the range bin with such defects - fortunately 9mm brass is so plentiful I just toss the bad ones away - in fact I don't even bother with 9mm range brass these days.

Fascinating!  I found the link, and found the drawings, along with the explanations.  Just one more thing I never heard of before, and now it has become part of my vocabulary.  

So, this is something that happens to all brass?  Do you and others ignore this, or do you buy another tool to correct it?

So, taking out the bend also makes the case longer.  

Only $1,100 with the extra sizes.  

I assume that for the light loads used in Bullseye, this isn't needed, unless we buy used brass.

Thank you, I think.  :-)

90% of bullseye guns donNOT have the problem.  Even the aftermarket barrels help.  But there are legions of people who have stock guns.

Mike,

Roll sizing has the biggest benefit if you process large quantities of brass. You can decap with a universal decap die with significantly less effort than a decap/sizing die, and then let the roll sizer do the work for sizing. It clearly has other benefits but to me the biggest is that it saves the effort of sizing. Personally I have no justification to have one.

From what I've read, this seems to be mostly for 9mm, as with all the poorly designed guns out there, 9mm brass is likely to include cases that are deformed.  With the huge amount of 9mm brass, thanks to what I read here, maybe there is a took that I can buy that just checks for bulged cases - or maybe forget all about this.  Maybe I should get a "match barrel" to check my reloads, if I can't get a tool to do so before the reloading.  

I just got my 9mm dies and other accessories, but haven't reloaded any rounds yet.  My "9mm kit" that LenV sent me is still on my reloading table, and last week I got to shoot my (only) 9mm gun, a Taurus PT92AFS.  My box of 400 rounds of remanufactured 9mm from Wilson arrived, and it shot pretty well, better than I anticipated.  

Are there other solutions to this problem, without the need to spend $1100 ?

Sure, Get a LEE Bulge Busting kit and get a Markov 9mm crimp die. Unscrew and remove the screw in adjustment. The lettering on my die is LEE-9mm-MAK-K5. Works like a charm. I had a Storm Lake barrel in my Glock that I used for IDPA and my reloads would not chamber. After bulge busting they would do the plunk test with no problem.

You can also inspect your brass before loading. The answer to this depends on how much it brass you have with the issue and how much you want to load

Now I understand:

Your Taurus is likely ok.  The real problem children are Glocks, but some other 9mm are problematic.  Taurus and their parent Berettas don’t have that issue. They have other issues, but poor chambers aren’t one of them.
