Interesting REVOLVER double tap discussion

[Fred in Florida]

This is ongoing at Revolver double tap - M14 Forum

"I recently picked up a smith 29-2 6”, and my first shot was a double tap.
I’ve never double tapped a revolver before including my sw460 mag beast.
Is that caused by limp wristing a 44mag? It’s been a while since I fired revolvers so maybe I’m just out of practice."

"It did give me a nice 2 shot group at 50yards but I want to avoid that reoccurring."

I seem to recall some discussion in the past about full-house .44 Mag ammo causing hammer rebound and double taps. Don't quote me on this, just jogged my memory bank.

The cylinder won't rotate a fresh round under the firing pin unless the trigger goes fully forward before the hammer comes back (again.) I'm not saying it can't happen, because I've heard of it before, but I'm having a hard time imagining the sequence of recoil, inertia and recovery forces that would move the trigger forward, then the hammer back (to recock the piece) and finally the trigger finger, which had to move forward with the trigger and then come back to press the trigger and release the recocked hammer.

I think it's called bump fire not double tap? I could be wrong of course.
This happened to me on a 6" 629-6 with a heavy 44 magnum load. Two shots in one.
One shot fired, cylinder spun landed on the next cylinder stop and fired another simultaneously-probably with the inertia and my own finger. One shot went into the target- the next went into the ceiling. It's only happened once. Stopped using those loads .
I dont really have a reason why really. The revolver was new and the loads were my remainder Ruger loads.

Clarify: not "ruger only "loads. My Ruger Redhawk loads. No. I dont fill cartridges up to the neck with powder anymore after I've became a Smith fan. Life is simpler I suppose.

This can happen in a heavy recoil gun, especially with a shooter that is not ready for the recoil, or just doesn't have enough grip strength to deal with it. What happens is, the first shot goes off, the gun recoils backward causing the gun hand to open and trigger to reset, then the recoil impulse is over and the hand recloses in an attempt to remain in control of the gun and is fired again.

I have seen 2 reports of this happening where a stupid guy thought it would be a fun trick to have a girl shoot their 500 Mag. The end result was that the gun flipped over and the 2nd shot blew their head off.

The 500 mag issue did actually happen, and the young girl died, in New London MO, a couple years ago. Tragic incident. Heavy recoiling guns should only be used by someone having experience with that type of handgun. Shoot a lot of 38's, then 357's, then 44's. You need to be in control.

There's plenty of videos of people nearly blasting themselves in the face with 500's.

I think I had a few sorta double taps in years past. I was doing fairly rapid fire, using a pull-squeeze. I think I did my pull part a bit early and as the gun came back down inadvertently finished the "squeeze". Not conducive to the rapid fire accuracy I was trying to achieve with the pull-squeeze. It would likely end with a flyer but otherwise the method worked well for me with the 6" 629 I was carrying. I was always a well above average shooter, superior to the vast majority of my peers, but never really competitive against true marksmen. Usually too nervous. Like with pool I'd shoot better after 1 - 2 (at most) beers but, well....

I had never shot a .44 Mag when I bought my first .44 Mag, a M29-2 with a trigger job. I fired the first shot, started to release my trigger finger so the action would reset, but the upward recoil caused me to DA the trigger and fire another round.

It took me most of a box of .44 Mags to realize what had happened, reason it out and to adapt the control my natural reflexes. I learned to hold the trigger back until the recoil had dissipated.

After that, when I let anyone who had never shot a .44 Mag, I only loaded one round in the cylinder!

I'e seen videos of this happening, and have a totally different theory as to why it occurs. My theory is that long barreled revolvers 6"+ firing heavy loads, cause excessive tork at the wrist, due to muzzle flip. The initial recoil force is rearward, then upward at the muzzle as the bullet leaves the barrel, and the pressure is released. The shooters finger comes off of the trigger causing it to reset, almost instantly. As the muzzle rises through its arc the whole gun is twisting upward in the shooters hand. The trigger is then pressing against the shooters finger, causing the second double action discharge. I can attest to the fact that the felt recoil from an 8" 629 full underlugged barrel, feels far worse to me, than the exact same load fired from a 4" 629 with a non underlugged barrel. Watch a few videos online, and let me know if my theory is full of baloney, and let me know.
