Not all 9mm brass created equal - got some chubbies?

[BrianV]

I'm new to reloading (and shooting handguns for that matter). I'm using a Dillon 550B, and I've done about 305 rounds so far (yep, 5 rounds was my first sample size with praying involved before pulling the trigger - even though I measured everything multiple times while reloading).

I'm a member of CGC, and the RSOs are great about not only allowing me to pick up my own brass - but sweeping other 9mm my way, too. The shooter next to me was shooting 9mm this last time, and he also sent me his brass since he doesn't reload.

So I'm getting a wide variety of brass for reloading, and I think I'm seeing a pattern. I've been using a 9mm gage, and everything slides in beautifully - until this last session. Now, I have 9mm CBC brass and a few Hornadys that are not fitting in the gage (just barely). These are all labeled 9mm Luger. The finished rounds are in my acceptable range for length of the round (in that 1.153 - 1.156 range). Other rounds I load before/after are fitting just fine with the same "stroke" used on the Dillon.

The ones that fit are Blazer, something marked FM, RP and FC - are these these the Remington, Federal American Eagle, and Winchester I've shot?

These chubby 9mm Luger rounds successfully came out of somebody else's 9mm - question is, is my Glock 19 forgiving enough to handle these little muffin tops?

Thanks for any advice - I have these little chubbies in a separate bin...just hoping I do not have to pull the bullets. And, I think I have a lot of that CBC brass that came my way on the last sweep!

[Hoser]

Did you try taking out your barrel and using it as a gauge?

[BrianV]

That was going to be my next step after reading a couple other threads. Shame I did things out of order because I just cleaned the gun, reloaded a bit more, and then wife came home and got to cooking some good stuff.

Thanks, I'll get to it.

[Irving]

I assume you mean they are fatter after you've resized them?

[BrianV]

I assume you mean they are fatter after you've resized them?

I don't think the resize is the issue (in this particular case...I know it can be in a lot of cases) - I think a few of these are fatter before I ever run through the first stage. I need to drop a few empties in the gage, and I bet they will still be fatter. And I have plenty of rounds before/after that do not have this issue.

[gnihcraes]

I check loaded rounds randomly on a case gauge. You'll find some that have a slight bulge at the very base. I've not seen those cause a problem chambering in a Sig or Glock so far.

[Hoser]

Gauges suck.

The only time they don't suck is when they are made with the exact same chamber reamer that cut your chamber.

If not, they are just a guide and normally wasted money.

Kinda agree, but I do find a lot of 38/357 cases that even after sizing won't fit the gauge or the chamber.

[KS63]

How many cases of 9mm do you have in stock? Break the fat ones down and toss em if they don't for your chamber. I try to stick to the same headstamp, but that's more my OCD talking.

I've considered doing that - especially since two brands seem to be causing most of my issues. Since I was a new reloader, I was hoarding the brass to get up a stock enough to reload a couple hundred at a time....which still isn't much!

[Not_A_Llama]

I'll buy your brass that you don't like.
Pragmatically, I can't recommend this viewpoint, but my glocks have eaten every casing that'a come out of my reloading press. I have literally never found a case gauge that was more generous than my OEM barrel chamber. This in probably close to 100k rounds.

Which is why I'm tempted to (1) use my Glock barrel as a gage for these 20 rounds, and then (2) try them if they fit. That will also give me some peace of mind and license to continue building up my brass supply with the help of the generous, non-reloading shooters around me.

EGW Undersize die 9mm

Problem solved, chambering issue gone, bullet set-back potential minimized.

No 9mm target load is high enough pressure to guppy a case beyond reuse. My 9mm brass is reloaded till I lose it, the primer pocket fails, or I can't read the headstamp. I cull any brass stamped F C (any stamped 'Federal' are retained) or stamped something I cannot determine. CBC, GFL, S&B, all fine.

Dang. Finally found a tme to disagree with you. I prefer to use the tightest gauge I find. That way, if it gauges there, it'll most certainly feed in any gun I own. If I just used the, say, Glock barrel, and then tried it in a STI, it probably isn't going to be 100%.

[rondog]

Check the fat ones closely, especially length. 9mm Makarov cases are very close to 9mm Luger, except a little shorter and a little fatter. Just a little. Headstamp might say 9mmMak, or 9mmM, or 9x18. You may even run into 9x19 9mm Luger brass that's been trimmed and resized to 9x18 9mm Makarov, it's very easy to convert 9x19 to 9x18. But the headstamp will still say 9mm Luger, or 9mm Para, or 9x19, etc.

Confused yet?

They definitely all say Luger. I didn't measure the brass by itself (length OR diameter), but I did measure the overall length after the reload. They are in-line with all of the "good" loads. I need to go back to some of my empty brass, before any resizing, and see if there is a noticeable difference in diameter.

I'll have to check out that die / although I was hoping I was done after this initial substantial investment...at least until I had some savings from the reload. And yes, I quickly realized there would be no savings - just license to shoot twice as much.

Interesting / I've had no issues with the FC but definite issues with CBC.

Do the drop test in your barrel before you do anything else. Take the barrel off the gun first.

That's my next step - got sidetracked last night (prepping for a Breckenridge/Fairplay weekend...not looking forward to the drive in these conditions). But I'll disassemble the gun and do the drop test before taking them to the range.

[muddywings]

ran into the CBC headstamp issue a few weeks back. a bunch didn't plunk. ETA: what I mean is the CBC stamped ones didn't plunk.

The Lee and the EGW are the same basically. Lee makes them for EGW based off of EGW's specs.

Loading 9mm Luger...about 5.4grains and 1.15ish in length

[RANGERRON72]

Brian, when I gauge my 9mm and sometimes they don't plunk in and out freely, if its practice ammo, and they are close to fully seating in the gauge, I go ahead and use them. For any competition matches or schools, I make sure they gauge without question. Make sure you are cycling the handle of your 550 all the way to get full length resized. Also, maybe adjust the sizing die down just a smidgen........ When I got the Dillon 650, I was getting a lot of 9mm that wouldn't gauge, and I played with the sizing die, but I still get a few that don't drop in freely......I am guessing its just a little longer case.

Also the comment above, 9mm Mak cases can slip into the pile, but I am guessing you have made sure its all 9mm Luger...... I have not seen particular problems with CBC, they seem to do fine....... Glad to hear the Dillon is working.......Be safe, have fun

All of the above is correct but in my experience CBC headstamp is crap brass. I'm trying to remember its source, somehow I want to say South African.

I reload it all the time except 40 S&W. I even reload their 5.56.

I'm telling you, the resizing die isn't getting low enough on the case and leaving a muffin top. Go to a "U" die and the problem is over. Been here, done this, tested multiple fixes, this is it.

[sportbikeco]

The normal lee dies go lower then other brand of dies it seems. What brand dies are you using? Are you maxing out the travel of the shell holder to the sizing die?

Everyone definitely seems to favor the dies to address this common issue. I'm using the dies that came with Dillon. I'm definitely pulling with the same stroke, and most of the rounds are having no issues with the muffin top. Perhaps the longer dies would address the issue...or, I just stay away from CBC brass. With all of these other brass manufacturers giving me no issues, I'd like to stick with the Dillon dies if at all possible.

Been out of town all weekend, so I haven't had a chance to try these rounds in the disassembled barrel itself.

Thanks for speaking from experience. Seems like the right dies address a lot of woes. I may run some experiments loading everything BUT CBC, and see if I run into any issues with the other brass. I'd really like to stick with the Dillon dies if I can...but not if this becomes a recurring issue regardless of brass manufacturer.

Sure, I just thought the other poster was asking Luger or Mak. FYI, I'm using RN plated...really meant to get FMJ first time around...my mistake on my first order from Xtreme.

FYI, in addition to the OAL=1.15 and powder weight of 5.4 grains, here are more specifics on the recipe:

Powder: BE-86 - 5.4 grains
Primers: CCI Small Pistol #500
Bullets: Xtreme 115g RN plated

[BrianV]

Finally had an opportunity to test how the rounds would fit in the Glock 19 barrel:

Good rounds - of which I've had about 285 (remember, just started). Notice the brands on the brass:

6519865199

Bad rounds - again, notice the brands on the brass. Had 20 of these:

6520065201

I just grabbed two rounds randomly from the two lots - all of the rounds are within a few thousandths of 1.15" in OAL....none above maybe 1.156". The good round is on the left, the bad round is on the right:

65202

Since those bad rounds aren't seating properly in the barrel, is it time for me to go buy a bullet puller?

[SA Friday]

Guppy brass... U-die, problem gone.

BTW, you have waaaaaay too much crimp. Crimp should lay the brass flat against the bullet and no more on an auto pistol round.

[sportbikeco]

post a better profile photo of the loaded rounds.

[Hoser]

1.150 is a touch long.

I might try 1.130 or so.

[BrianV]

Thanks for that input on "too much crimp" and length - I will adjust both for the next reloading session. I actually went with the 1.150 based upon watching a Dillon 550B setup video (How To Bob, I think).

[Not_A_Llama]

Something is very very wrong with your dies. Are they kissing the shell plate? Are they the right caliber?

Lee carbide dies are cheap and work very well.

As others have mentioned, "crimp" is really "de-bell".

[Irving]

Definitely way too much crimp (I did the same thing in my .40 S&W thread when I started). The ones that don't plunk, do they plunk after you push them down?

[Jamnanc]

I bet the tight crimp is pushing down too hard and bellying out the brass on those bad ones. Crimp just enough so the brass lays flat, bell the brass just enough so the bullet sits on there easily. If your worried about the bullet not being tight enough, measure a loaded round, push the tip into your bench "hard", then measure again, if it doesn't move, your good to go. Do this every once in a while even after you get comfortable. If you want, a lee factory crimp die will do a little resizing and "almost" works like an error check for these situations. They are about $19.

Outstanding info, folks...and I see everyone pushing those Lee dies ;)

[Not_A_Llama]

Just as a bit of theory as to why you don't "crimp" that way... Brass is a lot springier than lead. The brass will spring back from the crimp, but the lead won't.

Your bullet is retained in its case by the rubber band effect of a tight brass case mouth. It is also protected from setback by a couple factors, the first of which is the "waist" that develops when the resizer squashes down the case. The bullet must bell the case out progressively more to get deeper in the casing. You also have thicker case walls internally as you approach the case head.

(Vocab apologies for the MechEs - if you know about yield strength and Young's modulus, you're not learning anything anyway)


Lee dies are cheap and work well. If you can get over the idea of price not reflecting quality, you're set. They do have problems with not being long enough to achieve shellplate contact in certain presses with thick toolheads, though.

For all that holy on this planet, do not buy and use a Lee factory crimp die. They are a solution looking for a problem. Fix the problem, not try to do a work-around at the end. Lee FCD's will crush the sides of the bullet and resize the case after being fucked up at a different stage. This is not OK. Any lead or plated bullets will then keyhole and lead will lead your barrel. Don't crush the case with crimp. Use a U die to resize down to the webbing.

Lol, I have been exactly where you are right now and went straight to the Lee FCD. It causes more problems, not fix them. Fix the problem.

[Not_A_Llama]

I don't think the U-die is even necessary. The basic Lee sizing die that goes for $25 has not once in many tens of thousands of rounds ever produced a casing that wouldn't fit in my Glocks.

Tell ya what, Brian. Buy the Lee die. If it doesn't work for you, I'll buy it from you for the $25 it'll cost you.

Offer 2: mail some troublesome casings and bullets to me, or drop them off at Bowers. I will run them through my press and see if it is a problem. Or drop off assembled rounds and new bullets, and I will pull them.

The factory crimp die isn't cancer, but it's almost as bad.

I agree it isn't cancer, it's curable by just not using it.

As for the U die, I can prove it's worth the extra $15. I did a whole thread as to the danger of bullet set back years ago. https://www.ar-15.co/threads/16723-Bullet-Set-Back-Why-Some-Guns-Go-Kaboom?highlight=Set+back It just makes too much sense to use after the testing I did.

[Not_A_Llama]

To be entirely fair, and I recommend strongly against replicating or taking this as anything but an abnormality.. in 9mm, even hammering the bullet back to the point that the case almost won't chamber.. no KB.

Long days of practice and a curious mind can be dangerous.

Completely powder specific.

Out of curiosity, I grabbed some 9mm CBC cases I picked up at Centennial Gun Club that were shot from a striker fired pistol. I took my STI barrel and they dropped in. Next up I tried my CZ, which arguably, has a reportedly tighter chamber. Dropped in. For giggles, I resized them in my 550 with a Redding carbide sizing die. Fell in both chambers as expected. Measured and compared case wall thickness near the neck in CBC and Winchester brass that are shot in my pistols. The CBC, on my sample cases, measured .010"-.012" to the Winchester .009"-.010". If it were me and the majority of my brass is NOT CBC, toss or sell them. Not worth the headache.

I agree with the others, way too much crimp. When starting reloading, you will quickly learn with the expander and crimper that more is not better.

You guys are die-hards...or die snobs...or just have a buttload of experience and know what works.

Looking forward to a little tuning with my existing Dillon dies first - at resizing and crimping - then changing out if still struggling.

But this weekend focuses on the 22-yr old daughter graduating with her Master's...did I mention she did it while getting married and having two sons?!?

My latest reloads - adjusted the resizing stage, bullet seating die, and crimp stage. Still running about 1.15" OAL...fits the gage just fine...how's the crimp on these?

FYI, I really needed to move the resize die to come closer to the shell plate - didn't see the gap the first time.http://uploads.tapatalk-cdn.com/20160517/ab28269976a9ee71f5765bb111c5e364.jpg

I don't know shit about reloading compared to hoser so take this for what it's worth but this is what I was told and I"ll try to paraphrase-
After you seat the bullet, if you take it out and look top down you'll see the flare/belling and it will have a black line between the case and the bullet. (that black line/ring is the visual separation between the case and the bullet)
Back out your crimp die until it isn't crimping any more as a starting point then start moving it down a smidge at a time and relook each time to see when/where black line just barely disappears then stop.

ie: don't crush it

I hope that I got that right and if I didn't, I"m sure someone will tell me!

[BrianV]

Based upon what hoser said, I made another tweak to the crimping, and I think I'm getting at the edge of that "black line"(based upon the last pics, at an angle, you can see a seam vs appearing flush).

By the way, after all of the adjustments, the CBC...and all brands of brass in my collection...drop into the gage just fine.

No.More.Chubbies! I think the real culprit was that the resizing die wasn't making it down to the plate.

Lee 9mm U die, $19.99
