New Tool

[Doriangray6]

I reload a fair amount and just ordered a Universal Rollsizer from Double Alpha Academy in order to have better and longer lasting brass.
The nice thing about the Universal model is that along with the five handgun calibers I reload I can also use it for my 30-06 and 45-70 brass.

Universal Rollsizer

The Universal Rollsizer is an Adjustable Rollsizer capable of rollsizing all cases between 380ACP and 50BMG in one machine. Vernier accurate, high precision suited to low volume reloaders looking for the ultimate in accuracy.Your cases can be dialled in on the base to suit factory or custo...

My buddy has the DC unit. Works perfectly and it’s essentially production line ready for a commercial application. He has a few Glocks and fired cases suffer from the Glock bulge. If you don’t want lots of failures to feed you simply must roll size the cases.

I've read at several places that brass fired through Glocks have a really noticeable bulge.

I'm not familiar with this machine. Is it primarily needed only for brass that has been used in Glock pistols?

The cases have a bulge easily discernible by eye and by feel. The rollsizer is a must if you reload.

Primarily but I’ve noticed deformed cases fired from 1911 platforms on occasion. For those who invest in a rollsizer it soon becomes routine to size all cases to insure uniformity when reloading. Failure to feed becomes a thing of the past.
The price of a rollsizer makes it a perfect candidate for several friends to share the cost and use.

If you are getting bulges towards the base of the case it would be cheaper to replace the barrel on most pistols considering this roll tool costs a whopping $950.

If you are getting bulges in the cases coming out of a rifle you had better replace the barrel immediately or just not shoot it anymore.

Nice tool but it should be for that price. And I will not lie to you, I wish I had one because you can never have enough quality tools.

Unless a sizing die covers the entire length of a shell even brass without a bulge from firing will have a slight bulge at the base after it goes through a sizing die.
With the Rollsizer I'll be able to eliminate this on all my brass.

Just a few thoughts...Certainly a great tool for the purpose when needed. I've been handloading many handgun and rifle cartridges for sixty years. Three times I've had cartridges (all rifle cartridges) that wouldn't chamber after full-length sizing.

Twice, new sizing dies solved the problem. The third instance was with a batch (about 10%) out of a pile of once-fired .223 Remington brass that wouldn't chamber, probably due to being fired in an oversized chamber. The size die would not fully correct the problem. A roll sizer would have likely resolved the matter, but to discard a hundred or so pieces of cheap brass was of little concern.

I've never owned a Glock pistol and have no experience with bulged brass after firing in such guns.

I roll-size all my semi-auto brass I run through my 929, 610, and 625's. Gives me a little extra clearance for the fully loaded moon clip to slide in smoothly. It also helped reduce my ES and SD, I think by giving me a uniform case volume. I don't bother with my 38sp/357 brass. It didn't seem to make a difference.

 

[Petrov]

Semi auto brass is cheap enough. I invested in induction annealer to make my rifle brass last since I put so much effort into it.

 

[Imissedagain]

Can't remember where I recently read about 10mm brass, fired in Glocks, and the bulge issue.
Even when roll sizing, many advised to use that brass only for plinking loads.

 

[Petrov]

You can get those bulges out with a lee AP press , they have a pass through sizer.
That was mostly an issue with early 40 cal glocks

My Universal Rollersizer got here a couple of days ago so first I read the owner's manual then cleaned and inspected it and set up a spot for it on my work bench.
Ran 200 pieces of 9mm brass through it yesterday and though the crank is very easy to turn I could definitely feel the shells that had significant bulges.
Setting the size was easy; I just backed the micrometer adjuster out until the rollers were just touching the shell when I turned the crank and then gradually adjusted it inward while checking the shell's base dimension with a 0-1" micrometer after each adjustment until I got to the factory spec.
After that it was just a matter off putting shells in and taking them out and turning the crank.
Loaded the brass afterward using my Dillon Square Deal press and they did seem to go through the sizing die easier.
Next I'm going to run batches of my other brass through it. During the summer I'm just going to size and load enough brass for each trip to the range but in the winter it will be a great way to pass the time working my way through all my brass.

Certainly looks like a stout and extremely well constructed tool. I believe my eyeballs popped out on stalks at the very idea that I would even consider spending $950 to get the results this device provides, but if there is one thing I am dead sure certain of it's that you cannot accurately place a price on pride and confidence in one's handloads. What I am saying is that if this device gives you confidence in your ammo, that pays off without question or argument. Frankly, I believe the confidence in your loads can help you to shoot better, I truly believe that.

I do have an issue with this part of the conversation. And there are many ways to skin this cat. First of all, it's been long proven many years ago with real evidence that the Glock and it's inherent lack of case head support (which leads to the bulge or "Glock Smiley" has evolved as the guns themselves evolved. It was absolutely at it's worst with the Gen 2 Glock 22, 23 and 27 pistols in .40cal and Glock engineered later guns to have MORE case head support and reduce the occurrence of the the bulge.

Secondly, as was suggested, another fantastic way to get better case head support is to buy an aftermarket replacement barrel and last I checked, a billion manufacturers offer them. Well, maybe less than a billion, but you get the idea.

Thirdly, and most importantly, it's simply a BAD idea to roll size or even use a push-through sizer or "bulge buster" to attempt to fix a piece of bulged pistol brass. The damage here is done, you've merely given the outside a facelift and the structural integrity is suspect.

This ends up being much worse than a piece of bulged brass because a typical piece of bulged, wrecked brass is nice enough to appear bad, wrecked, and dangerous.

One of my favorite comedians quipped, "What's the difference between Charles Manson and every woman I have ever dated? Manson had the decency to look like a nut when you first meet him!"

And it's the same with bulged brass. Subjecting a piece of brass to 35,000 or 37,500 PSI when it's structural integrity is destroyed is a BAD IDEA I wish that folks would never attempt to do this.

Annealing might fix that, a roll sizer never could, and a roll sizer makes it almost look good and safe... when it isn't.

Confusing. So you're saying that even just running brass through a regular sizing die is a bad idea? Because all brass, even when it's completely supported in a cylinder or chamber, expands from pressure when fired. Brass with a bulged area at the base has just expanded unevenly.
Ideally the best thing to do with used brass would be to anneal it first to soften it then size it back to the correct dimension and a friend of mine that shoots extreme long distance matches with rifles and revolvers does exactly this with his brass and keeps track of and limits the amount of times he reloads each piece. He has also hunted big-exotic game all over the world and at times has had to take shots at very long distances.
Of course he's competing and sometimes hunting with custom built or modified revolvers and single shot or bolt action rifles usually chambered for very high pressure wildcat ammo for this rather than auto loader firearms because he says that auto loaders don't handle pressure as well so cases with unevenly bulged bases aren't a concern.
He has and shoots auto loader firearms, including several 44 mag and 50 BMG Desert Eagle pistols, but says they just don't work well enough for his competition needs.
I don't shoot at that level though and don't feel a need to go through the extra steps that he does so for the kind of shooting I do the Rollsizer will work fine for all my brass.
