9mm brass...tight
I bought some Speer once fired brass, and am having a hard time sizing it to fit the chamber of my Kahr K9. My question is: is this normal for Speer or has the brass been fired in a full auto or some other weapon with a loose chamber? It's only the Speer I'm having trouble with, and I bought it all at the same time. PMC, FC, Winchester...they all work ok, no problems.

Thanks.

My K9 has no problem with speer brass and any other brass.... I do one thing though....use the LEE PRECISION FACTORY CRIMP DIE....they chamber without ANY problems now!!

If the brass was previously fired in a Glock, the case head could be bulged and the resizing die will probably not remove all of that bulge.

The Glock factor may be the problem. The case head is tight...resized brass sticks before it even gets all the way into the chamber, even without a bullet. Guess I'll trash it.

Thanks.

This is most common with dillon resizeing dies. Dillon has a large flare so the empty case will go into the sizeing die with ease, but results in not sizeing quite as close to the base of the case.

Lee factory crimp dies resize the most. Because it depends on the bullet to feed the case into the die, it can get by with very little taper. As expected with lee, I have seen some variation in how much flare exist in these dies.

Do you use a case gauge?

I contaminated my 9mm brass with some I picked up at the range, apparently fired in a subgun. I made 100 cartridges and then checked them in the gauge. 50 of them failed and I had to pull them.

I ended up resizing all to the brass and checking it prior to the normal reloading procedure. I found about 150 bad cases. I am not going to scrounge brass at the police range anymore.

Jerry, thanks for the info. The problem isn't with the bullet end. The case head was expanded to the point that it wouldn't resize adequately.

El Viejo, no, I haven't used a gage. After I had problems, I disassembled the gun and tried dropping the cases into the barrel. That batch of brass was the only one I had problems with. All the others fell all the way into the chamber. I suspect you are correct, that the brass was fired in a weapon(s) with a loose chamber. I've disposed of it.

Thanks to all. I've only reloaded 9mm for about a year and was unaware of problem with Glocks and SMG's. I'll check each batch before reloading, now.
