aluminum cased ammo

[dlh]

I understand all of that. I have been shooting guns for 55 years.

How do you explain this...

I fired until the gun would shoot no more. The slide locked back.

There was an unfired last round in the chamber with no primer strike...I have never had a primer strike issue with this gun before.

I'm going to have to go with the haunted option then


OT, but related to blazer ammo : their 9mm FMJ ammo rates poorly in lightweight revolvers due to crimp jump. On 2 separate cylinder loads, after firing 4 rounds (Ruger LCR 9mm), the 5th bullet completely left its case. There is an ammo review online for a different 9mm lightweight revolver ( can't remember which atm,) that rated the blazer ammo very poorly as well. While the Speer lawman FMJ I tested did not leave the case, it had the 2nd greatest crimp jump of the different ammo I've tested in the LCR 9mm thus far. Just a tidbit...obviously the ammo wasn't intended for revolvers.

Perhaps I should just break down and buy an AK-47. Folks say it is not cranky and will shoot any kind of ammo.

It's not up to us to explain it, it's up to you. Next time take some video. Trust me, you'll go down in the history books - or not.

And how exactly did the aluminum case round cause that primer strike issue? By your own words your gun didn't touch the primer. Was the round supposed to go talk the firing pin out of the housing all by itself?

I'm going to leave you with a challenge here. Find someone who reloads. Give him a round of aluminum case 45 ammo. Ask him to pull the bullet and primer. Ask him then to put a spent primer and no powder in the case and reseat the bullet. Take your mag and put that bullet in first, then one good live round in on top of it and go shoot that live round. Then you come back and tell us if the slide cycled and locked open leaving your dummy round in the chamber. Or you can do it the easy way and use a Snap Cap instead of the doctored round. Deal?

Otherwise, nothing personal here, but I think I've wasted enough time with your pot stirring.

I noticed that with the bullets a lot of manufacturers use for traditional semi-auto rounds fired in revolvers. I had that problem with brass cases in a S&W Model 25 in .45 ACP. The bullets with no cannelure don't get enough crimp. Blazer aluminum cases make it worse because the metal is not as maleable as brass so you get even less crimp. That can be dangerous because the bullets can set back in the case under recoil in a revolver, compress the powder charge, and greatly increase the pressure levels.

I ran two box's of the cheap aluminum case 9mm through a Marlin Camp nine rifle and two box's through a Ruger and a Beretta pistol . Experienced no problems at all , was just curious to try in .

The unfired round was also the last round in the magazine as there were no other rounds in the magazine/feed ramp when the gun locked back. I have never had a failure to strike a primer with this handgun. I don't believe in haunted things though the movie Ouija was mildly entertaining. :)

Wow, you are sure taking a beating on this. Really hard to explain. Is it at all possible that there is a mag problem, the last round was not settled well into the mag, just at the instant the next to the last round fired, locked back the bolt, the mag spring popped the haunted last round out of the mag and it self guided into the chamber while the bolt was locking back. We know that the lock back can only occur when the mag is empty but the only way this could occur is if the gun sensed an empty mag and the tolerances of either the gun or mag are off enough to make the gun think the mag was empty. I can see a cartridge might be guided into the chamber and you described a loose fit as the cartridge easily fell out of the chamber. I know this is way off but if it happened as you said there has to be an explanation or else as implied the gun is haunted.

[dlh]

I posted asking for an explanation. You provided none. You wasted my time.

During one outing to break in a new 1911, I had a couple of instances where the slide locked back and when I looked in, there was an unfired round sitting on top of the magazine. It had apparently popped out of the mag instead of politely waiting for the slide to strip it out.

If I had tilted the barrel down at (or close to) straight down, I suppose the round could have slid into the chamber.

That's still a stretch, though.

[dlh]

Thanks Rotor had not thought about that.

This is about what I was describing and sounds like the only reasonable explanation. I don't know if this has anything to do with the fact that aluminum ammo was used vs. brass. I think it's coincidence.

[dlh]

Thanks rotor.

I was using a Wilson Combat magazine...thought it was in good shape. I shot a mag. of Winchester brass through it after this incident and had no problems.

Tomorrow I will go back to my range and shoot the rest of the Blazer aluminum ammo in the box and see if I can replicate it.

Thanks pawpaw.

I have fired about 500 rounds through this 1911 so it is not new. I previously had problems with failure to eject or failure to feed with the factory magazine that came with the gun but those problems disappeared when I replaced it with a Wilson Combat magazine.

Will shoot some of that ammo again tomorrow and see what happens.

I apologize if you thought I was being rude. You claim to have been shooting for 55 years. Fair enough, but I would think if that was the case you would know, assuming you do understand the 1911 pistol, that what I described to you is precisely how the weapon works. The only logical conclusion would be that such a thing could not happen. You assert that it was caused by aluminum case ammunition. I haven't heard you say a single thing to indicate that you have any idea how such a thing could even happen, much less how aluminum case ammunition caused it.

Then you post that no one has helped you figure this out. I think you've gotten as much of an answer as anybody could possibly give you. It had to be, as PawPaw suggested, a one in a million fluke caused by failure of a magazine to properly present a round to the bolt face.

You should know, as much experience as you claim to have, that a lot of people post outlandish things just to stir the pot. When you demand we tell you how something happened that is not understandable in my 62 years of shooting, 52 years of shooting 1911's, including 14 seasons of NRA competition with 1911's and no one else has a logical answer either, then I'm not sure what you want from us. Again if you thought I came across as rude, I had no intention of doing so.

@ ShootDontTalk

Apology accepted. However, I never "demanded" (those are your words) that somebody tell me how this event could have happened. I simply asked for an explanation and I perceived your comments as rude and condescending. So be it.

I have been shooting since I was seven years old ( I am now 62) and have shot all kinds of firearms (shotguns, pistols, rifles, etc. in single-shot, bolt action, semi-automatic etc.) I certainly know how a 1911 operates and did not need the lecture you gave above.

The Winchester brass fired just fine with no problems so I thought it might have been the aluminum ammo but I was not certain---that is why I came here and asked if anybody else had any similar experiences.

As I said, tomorrow I will go to my range and shoot the rest of the Blazer aluminum ammo and see what happens and if I can replicate the problem again.
