Yes, usually you can use small rifle primers in most small pistol applications. Can I use small rifle primers in 9mm Steyr reloads? Sometimes you have to do what you have to do in order to just get by. In addition to that, there have been primer shortages, and ammo shortages. Obviously, we recommend that you try to stick with accepted load data, however, not every gun is the same, and sometimes a gun responds better to one powder or primer better than another. In the end if you are following good reloading procedures, load light and build up to what you want with either one.” Why use other sizes of primers other than what’s in load data? You can over pressure the case quick so be careful. You need to burn a lot of powder quickly. I asked my personal gun smith, who also taught me to reload his opinion on small pistol vs small pistol magnum and this is what he said about it: “I’ve tried both. Most pistols do have the strength to ignite primers much stronger than just a small pistol primer. If you’re watching pressure, you can usually load a thicker primer, as long as your hammer and firing pin has the strength to ignite the primer. The bigger the primer, the thicker the cup, and the more or different explosive material is in the primer. Primers have a metal outside, called a cup, and the small explosive charge used to ignite the powder in a cartridge. Yes, you can usually get away with using small pistol magnum primers.

#Things you should watch out for on 9mm primers manuals

We use reloading manuals from Hornady, Lee, Berger, and others.

We like to confirm with multiple published sources. We like to verify primer information and all other reloading data from multiple sources, so we recommend that you do this as well. The 9mm Steyr cartridge takes a small pistol primer. What size primer does the 9mm Steyr take? It was adopted in 1912 by the Austro-Hungarian military, and remained in service until the fall of Austria-Hungary in 1918. The 9mm Steyr cartridge, also called the 9x23mm Steyr, was created by the Austrian company Steyr Mannlicher for their M1912 pistol. When developing a new load for your 9mm Steyr, or any caliber, you should start with smaller amounts of powder and pressure and work up gradually. This article looks at theory and our experience, and should not be considered recommendations about primers for the 9mm Steyr. Extreme caution should be taken when creating loads that go against accepted load data. I'm also attaching a photo of a couple of rejects I ran into.Please note that this article looks at research and testing done by a variety of sources. Once the primers were removed the cases slid into the shell holder without an issue.Īnyone care to hazard an opinion or has anyone run into anything like this? Since I could not get the cases into the shell holder, I removed the de-capping assembly from the used it to tap out the primers using another shell holder as a base. Honestly, all the cases that entered the shell holder de-primed with normal effort. Will very low-pressure loads produce raised primers (not enough rearward force to slam the cartridge base into the breech face to reseat the primer)? Since I do not have any history on these cases, could the pockets have started to open up? The primers were rounded with no signs of flattening, flowing, or cratering. Now I'm trying to guess why the primers were backed out. Without the relief cut, the slightly raised primer would not allow the case to enter the shell holder. All the other shell holders have a relief cut from the mouth of the shell holder to the primer hole. They are pretty standard with grooves to hold on to the rim, a hole for the primer arm/spent primer to clear the holder, then I did notice a difference. Then I looked at the hole for the primer arm/spent primer and noticed a small difference. I rechecked to number (RCBS #29) and it was correct. Since some of the cases had identical head stamps to some that worked easily, I started looking at the shell holder. The cases that would not slide into the shell holder felt like I was trying to shove them through a brick wall, I mean solid. They may not have all been from the same weapon.

Since these were gifted cases, I have no idea what pistol and the condition of the pistol they were fired in.

Most of the lot slid in and out without any issues. Now these were not magnum or high-pressure rounds, they were. While processing some 'Gifted Brass' today I ran across about 20-cases that the primers had backed slightly out, enough to not allow the case to slide into the shell holder.
