Double tap 5.56 vs. single tap 7.62 times

This is an imbecilic question from the OP. Rephrase your question so we may understand what you are actually asking and why you are asking it. It may take a few minutes of thinking and forming thoughts but that way you won't waste people's time trying to decipher your post.

ETA - What do you mean by double taping? 2 shots with one sight picture or do you actually mean controlled pairs?

[sboza]

Just gonna throw this in here. You shoot based on your skill level which means, for most people, shooting upper thoracic until the threat goes down or you realize the threat isn't going down and shift to lower percentage targets (head, pelvic girdle). This is oversimplified and there are various ways to handle multiple threats based on your training level, teammates, mission, etc... Don't get caught up in this nonsense about a "double tap" being necessary for one caliber over another.

Off topic a bit but I read from a grand master shooter that if a shot needed a sight picture then each one does. There are times when your close enough you don't need a sight picture then don't take one just index and shoot. However if you do need a sight picture each shot should get one. Your actually faster this way. Your shot cadance should be bang, bang, bang,bang not bang bang, pause bang bang pause. What your calling a double tap by the way is generally called a Hammer while a controlled pair is often called a double tap.

First, take a look at this:
http://m4carbine.net/showthread.php?t=19207
little thread about the "double tap".

Second:
I can shoot a Half and Half drill (mostly) clean (on a 5x8 card) with an 18" 7.62 PredatAR with a Leupy 1-8 with almost no warm up. So can my buddy, the owner of said beast.

Split times are a function of trigger manipulation.
Presentation time is a function of the shooter's ability to rapidly acquire sight picture.
Rapid multiple shot accuracy is a result of a good position while incorporating the above.
Rapid, accurate target transitions are achieved by getting the gun moving off one target and stopped on another as quickly as possible.
If the shooter knows how to present the gun and transition from target to target, he will be faster with the gun that he can both move and stop the fastest. If shooting guns with comparable weight/inertia, shooting a single shot will be faster than shooting a pair. Drastically change weight/inertia and that can change (think 10/22 vs M82A1), as can sighting system (think EoTech vs 25x traditional scope).

Again.

Let's just compare the performance of the two:

Are two 5.56 FMJ bullets will have a greater penetration (at the same point of impact) than one bullet of 7.62 FMJ?

Are two 5.56 bullets will have a greater stopping power than one 7.62?

Look, I did not mean to make it hard for you.

Thanks to those who offered substantive replies.

Why double tap at all?

Don't rely on any set amount of shots to take down a threat. Do not stop shooting until you know the threat is eliminated, that's the only real way to go.

(Not directed at you OP)
People who don't earn their living using a gun as a tool often model their behavior after those that do...but they don't know why. They'll hear double tap and see it on the internet or in movies and not know the difference between a hammer pair & controlled pair (not as sexy I guess)


(Directed at you OP)
At the end of the day, the reason you shoot someone is to kill them, which means they were either trying to kill you or a loved one. (after mastery of fundamental marksmanship) Your training should reflect your enviroment and the threats you're likely to encounter. The tool you use to eliminate those threats should be your most effective one using common sense.

Just like I tell people that ask the "what's better 9mm or .45" , The best one is the one that YOU can make the most accurate shots as fast as your skill level dictates.

From a distance that you'd be "double tapping" someone, the difference between 2 well placed 5.56's and 1 well placed 7.62 is purely academic, if you did your job the rounds will do theirs...dead is dead.

... and dont stop tracking sights.

Everytime I tried(when I was first starting), and I see others attempt to double tap, the first round hits and the 2nd is wasted just making the 2nd hit take about 3x longer than it should have.

That is if its a true "double tap."
