causes of keyholing

[nwfredkali]

What are the causes of "keyholing". I recently got a new pistol and about 20% of the bullets are perfectly sideways at 7 yards. It is worse with Federal 38 grain bulk but is still present with Federal 40 grain. The manufacturer sent me a new barrel and it does it too.

I would hazard to guess it's a 22 LR pistol. How long is is the barrel? Sounds like it is short barrel and can't stabilize the bullets after they exit.

What is the make and model? Sounds like too slow of a twist rate but I think pretty much all modern 22lr barrels whether rifle or pistol, have a 1/16 twist which should easily stabilize those bullets.

Improper twist rate for the bullet weight. It's that simple.

This.
Either too slow of velocity (not enough spin stability) or not enough twist for velocity

Sometimes something crazy happens like getting a smooth bore. We got a big order of new duty pistols and some had no rifling at all.

What kind of target are you shooting at? If it's just a hanging piece of paper some of the shots will appear to keyhole but in fact its just the paper giving.

 

[JuglansRegia]

sounds like an oversized bore and or no rifling.

friend bought a ruger wrangler that started out keyholing about fifty percent. took about 500 rounds to settle down. shoots ok now. never did figure it out, but if it's a wrangler,shoot more. i'm thinking burrs.

It's the earths rotation.
Shoot in the opposite direction.

Stop trying to curve your shots like in the movie Wanted. Thats hollyweird.

They fat end trying to catch up with the skinny end?

New Joe Biden ammo

I think that would be "cornholing" not "keyholing"

 

[HighlandLofts]

I agree it is probably Biden corn holeing ammo.

 

[MrTwentyTwo]

Pix of the gun (if not the make and model), plus a pix of the target holes. Possibly, have someone (or you, with the proper tools/machines and ability), put a good target crown on the barrel.

I think maybe Cornpopping?

Throat may be too deep...

Is it a Taurus TX22?

I had a problem with keyholing when shooting my Ruger Wrangler last year.

When I shot CCI it was a tack driver...but I had a large box Federal black box (38gr I believe) that almost all keyholed.

Try different brands of ammunition. If the results are the same for all the ammo then its the pistol. If conditions improve with different brands then it's the ammo.
