Feed problems with Self Defense ammo

I was having trouble with Federal self Defense rounds not Chambering, So I did a little test. I have a hard time believing its ok for there to be this much difference in the length of ammo. You tell me. The ball ammo works flawless. I don't have the box at work the federal ammo came from, but I can identify it when I get home.

I have found that variance you noticed across all brands and within brands. If you've a Kimber 45acp, you might find that the shorter rounds might not chamber due to the controlled feeding system of the basic 1911 design. Also, due to Kimbers very tight machining tolerances, I had to have my Kimber's chamber throated/reamed, very slightly beveled, and polish the feed ramp. Some brands of rounds simply were too wide for the chamber. Now it handles anything I feed it and accuracy remained the same.

EDIT: I would emphasize going to a Kimber certified armorer to check your weapon. When I did, he had just completed the same task for another Kimber owner.

I am for sure a Kimber Man. lol My pistol worked perfect till I tried this ammo. I would love to have some of the polishing and stuff done one day. I just think its bad there can be that much difference between rounds .

Or you could try different SD ammo. That might help. Winchester PDX1 works perfectly in my three.

Find an ammo that works and stick with it. This is exactly the reason why they tell you to shoot plenty of ammo you will be depending on to make sure you can rely on it. Ball ammo almost always works. Hollow points, flat nose, etc., have less chances. I use Lax or Freedom for target. Critical Defense for hd... They all work religiously in mine.

This is what I normally use but I shot them all up. I found 100 rounds of the federals in my safe and thought I would try them. They are not going to work. LOL I will look at your Winchesters PDX1 also. In the mean time I will stop in and grab my an other box of what I know works good.

I manly wanted to show the difference between the length of the rounds just incase anyone else was experiencing the same problem , So they could look see if that was the issue. I will just shoot the federals up at the range in my desert warrior. that thing will shoot anything you put in it. Everytime I go to the range I take my everyday carry and empty the magazine of my self defense ammo. I just didn't realize I was out, so I thought I would try what I had already had. I wont make that mistake again.

About 30 years ago I read an article by Massad Ayoob on loading his 1911 and checking the ammunition. Handloaders know that you can use your individual barrel of your pistol as a "go, no go" gauge. You dump out several cartridges, drop them into the chamber and see which rims line up level to the rear of the hood--none under, none over.

The rest are for practice.

I know that Hornady Critical Defense and Guard Dog ammunition feeds in my UC2. I got spotty performance with the HST rounds, although that happened when the pistol was new and tight.

John hit the nail on the head. Just because one brand of ammo works well in one of your guns that doesn't mean it will work the same way in all of your guns. Each of your carry guns have to be thoroughly tested to find the SD ammo it likes.

If I had to guess I bet I have probably spent a few hundred dollars finding the right SD ammo for all of my Kimbers and making sure they go bang when I would need it most...
