My .45 is keyholing!

How dare you post a gun related question in GD!

j/k

Does it keyhole with other brands, or just American Eagle?

Bullets hitting the target sideways, IIRC.

On an unrelated note, last week I saw an 1/12 twist AR keyhole 77 grain ammo at 7 yards.

American express? Since when did the credit card guys get into ammo?

All AR's do that.  Cause the bullet tumbles right out of the barrel.  It's makes it kill gooder.  

Yes.  I am kidding.

No advice but I hope this is a problem with your pistol and not the ammo, cause I just bought 500 rounds of the same ammo....... Does it do it with other brands? How many rounds do you have through it?

I do not know if it does it with wolf ammo.

That there is yer problem...

Some 1/9 will shoot 77gr ammo, but 1/7 is recomended.

Try longer range & see if it still does it.

Everyone knows the bullets tumble when they hit you and keep tumbling until they find a blood vessel.  They they straighten out and follow the artery or vein to your heart.

Are you sure that isn't .40 caliber ammo?  

Tagged for interest.  This is bizarre.

g3shooter: Your barrel is not stabliizing the bullet correctly.  I would try another brand of ammo, if you still get keyholing, then I would return the gun to SA, and tell them what happen.  You get keyholing when the barrel doesn't spin the bullet fast enough in order stabilize it's flight.

Or when it overspins the bullet.  That happens in one of my Swedish Mausers when I use small (i.e. short) bullets.

Take it apart and check the bore for leading, [have you shot lead bullets in the past?] how the rifling looks against another BBL and a ring that might indicate a squib load followed by a normal one.

You could always have a bad batch of ammo with undersize bullets. Can you shoot in an area where you can recover a spent bullet?

If it has worked fine in the past, I'd try another make of ammo before I start to worry.

I just took a closer look at the targets, it looks like it was the way that the target tore. I may not have a keyholing problem after all.

I was wondering what the heck a 45 keyhole looks like. a 223 is an oblong round.  45 is just kind of a lump

It would be extremely rare for a 1911 to keyhole with any standard ammo.

If you are used to little holes made by wussy rounds like 9mms and such I can see that you might be confused.

is it rifled?

don't laugh saw a  new colt with a smooth bore at a gun show years ago

keyholeing in a handgun is pretty unusal and indicates major problems

send it to SA

lately we have had a fair number of problems with springfield GIs had to send a few back
nothing with the barrels or accracy problems though

Thought:  If the targets are just hanging, or the cardboard behind them is all shot up, try backing them with cardboard, foamboard, or whatever is handy.

You don't know what the heck yer talkin' about. An AR is only supposed to WOUND the enemy. That ways it takes out 3 of them instead of just 1 cause his 2 buddies will have to carry him out.

Sure you're not holding the Pistol sideways?
