So...what's the deal with some 45 LC cases having the "hump" inside the base above the primer pocket? I recently prepared to begin to reload this caliber, and I guess I never noticed this before.


The one on the left has it...and both are Remington Peters cases. (It doesn't correlate to brass or nickel composition within my batch of brass, for those who might be wondering).


Is one kind better for shooting horse thieves than the other?

I like to shoot my horse thieves with a .44 Russian or .44 S&W special in a break action Schofield type revolver.

I suspect that the "hump" is there to reduce case capacity which may be beneficial for certain target loads in which the powder charge does not adequately fill the case.

Called the "Super Balloon". Low pressure hulls are made in this manner, although some high pressure loads have been offered in such hulls.

The "hump" cases are called balloon-head cases. They are old and not as strong as the newer cases. Mike

Federal used the Super Balloon design for their 40 brass when the round first came out. A new term was created because of this. "Glock Kaboom", although Glock is not the only 40 that would not tolerate this ammo. High Pressure loads in Low Pressure brass is a recipe for disaster.

The photo shows 2 40 cal cases, one is the old style Federal and the other is the new style. It is hard to understand why an ammo maker would do this. To this day they have never admitted they blew up a bunch of guns.

Well...I sure would like to get my hands on the bastard who came up with the idea of those "small primer" 45 acp shells that have been hanging up the deprime punch of my loader so bad!

Small primers make sense for the 45. At its inception, the same tooling that the 30/06 was made on was used for the 45 case head.

I despised the SP brass when it came out, but ammo loaded with this primer is more accurate.

I still despise sorting brass by headstamp, THEN BY PRIMER SIZE. Oh well, it has to be done.

Thank God for Starline Brass. I refuse to go along with this "Small Primers in 45 acp" foolishness! For what components cost...take your incremental continuous improvement, and either use it to give us something genuinely useful...or shove it!

Shooting Coach hit the nail on the head for the balloon cases.

A word of caution. They should only be loaded to blackpowder pressure levels. Don't try to jack the pressures up. Use the modern solid head cases for that.

BTW, not shown in Shooting Coach's chart and photo are "inside primed cases". These look like the folded head case, but there is no visible primer. They look more like a big rimfire. The base of the case is so thin on the inside primed cases that it will readily dent from a firing pin, setting off the hidden primer inside. I have examples of these in .45 S&W (sometimes called .45 Schofield or .45 Short Colt), .45 Colt, and .45-70 Govt. All of my examples have cases made from copper, not brass. The 45-70 version was notorious for being sliced through by the extractor on the Trapdoor Springfield.

FWIW, The 230 grain FMJ Blazer .45acp, the aluminum case ones, have SP primers in them. Been using them for years, and is the most accurate factory ammo I've ever shot out of my Sig 220.

My 1894 Marlin chambered in 45 Colt -- I don't think you could ask for a more handy but devastating brush gun!

Kiv, I have one of those Marlin 1894 Cowboy Guns in 45 Colt as a companion to my pair of Schofields. Used to used them for cowboy shoots with blackpowder. Sweet shooting rifle.

Well, it's not exactly a .45 LC, but, it uses shortened .45 "Cowboy" special brass...
