Reloaded 9mm question?

This can be a common situation when +P cases from some manufacturers are used with long bullets. I went through a bad patch twenty five years ago with Winchester 38 Special +P cases and the wadcutters I was shooting PPC. The bulges would make foe hard chambering, real PIA until I sorted out all the Winchester cases and gave them away. Resorted to using Federal +P cases and never had another problem. Their cases did not have the tapered thicker wall of the Winchesters. If the chamber is tight you get the same effect, we also encountered it with US made 32S&W long match cases. The effects are very dependent on the case, bullet, and chamber dimensions.

Sorry, I have to disagree, there is 100% nothing wrong with the pictured reloads, they have been sized with either a Dillon die or an under size die which is done on purpose with a taper to make sure cases are not oversize, when reloading multiple brands of brass with different thickness walls its not uncommon for some to spring back after sizing and be over size and cause problems when chambering the round, this also makes the case slightly smaller than the projectile which eliminates problems with bullet set back and reduces the need for extra crimp, plus when the case is sized with a taper is releases easier on the down stroke when being removed from the sizing die.

Frankly, I have no idea how remanufactured ammunition is made, but if they use similar processes to you and I then you could be right on what's causing it. But that still doesn't mean the cases are in spec. One of the reasons 9x19 is so reliable is because of the straight taper case. These are no longer a straight taper case. :)

To my eye it looks more like case buckling (rather than springback), which is a more serious problem.

Again, I probably wouldn't worry about shooting it (outside of a match), but I'd still let the manufacturer know. They could have equipment out of adjustment or a bad bunch of brass and not know it.
 
I am conflicted. Ganderite has reloaded more 9 mm than I have everything and he really seems to be on the ball. I have reloaded > 10000 9mm and I'd agree with alpining that those ain't "right". There is always a ridge in the case where the projectile base ends but that deformation ain't about that. I mean that is well past where a 147 grain would sit in the case. Will they work if they punk? I'd say for sure. Is that normal or right? I'd say no. I am no expert but I have reloaded a few of these and I would say that there is a seating/crimping timing problem. As an amateur I'd be unhappy with this and try to sort it out.
 
You see this more often when you load lead bullets sized .357 which is what I size my lead bullets to. If they drop into your chamber via the plunk test shoot them. An undersized die will do this. I have seen once fired Aquilla brass, the type with the crimp about half way down the case buckle at the grove and become unshootable but that is not what we see here.

Take Care

I have fired a few of those in 9mm and you really won't notice any difference when firing and no evidence on the brass at all after being fired, it will be ironed out completely.

I recently bought a bulk case of commercially reloaded 9mm. I've used commercial reloads from a variety of companies in the past but this is my 1st experience with this outfit.

I have noticed that a significant percentage of these cartridges have a slight but noticeable ring or bulge around the casing about 1/2 way up from the rim. Is this anything to worry about. I haven't noticed this before in other ammo. You can feel it with your finger and it is enough to catch your eye. Anything to worry about?

Sorry if this is a stupid question but I know next to nothing about reloading.

Crappy cellphone photo but hopefully it shows up.

I load Berry's and Rainier plated .356 bullets as well as Lee Tumble Lube and Single Groove bullets sized to .356.

That bulge happens to me as well for some brands of cases, i.e. Winchester, IVI, S&B, R-P, GECO

However, Federal and Speer cases have considerably less bulging, sometimes there is nary a bulge.

I think the difference is that Federal and Speer cases have thinner walls at the neck.

Either way, bulge or no bulge, I have no issues with feeding.

Good data, thanks. What type of crimp are you using? Have you measured case length?

Again, just because it works doesn't mean it's in spec.

Interesting responses. Bulging cases being normalized,, what??? Have not loaded 9mm, but many, many other calibers. If I had a reload come out looking like that I would investigate and remedy the problem. Passing a so called "plunk test" with a round loaded like that suggests a few issues, possibly including that the firearm may have a questionable chamber as well.

Some of you just don't get it, there's nothing wrong with that ammo. Below is a picture of my 9mm reloads. God knows how many I've loaded over the years (150K+) and I've never had a problem. I verify all completed rounds with a Shockbottle Hundo gauge and my rejection rate is less than 1%. Some 9mm dies, especially Dillon, produce a coke bottle/wasp waist shape which provides good case tension.

Good to know I never noticed that advantage thanks
