How speed shooters aim their gun so quickly

[9mmepiphany]

Sorry,
but what was the title of this thread? I think the ammo used by these speed shooters adds some weight to the answer.

The title is "How speed shooters aim their gun so quickly "...with the active verb being "to aim"

The OP then goes on to elaborate with:

In almost every case, as soon as the gun had been extended out away from their body, they took the first shot.

My question is how they learned to extend the gun, such that it was perfectly aimed at the target?

In your opinion, where does ammo address aiming and extending...which would seem to directly address lining up the sights for a first shot

It doesn't, so I guess a follow up shot is irrelevant and should not be considered.

 

[9mmepiphany]

Only in this discussion, that is why I have asked, if that discussion interest enough folks, that they start a new thread

The technique of making a fast first shot is very different than that of making fast followup shots. That is why they should be learned and practiced separately

 

[joneb]

Sorry, I did not realize how narrow the field of view is here.

No problem, refocusing threads to prevent overt drift is part of the goal

It allows later readers to more easily search for focused discussions

If you guys want to talk about ammo and power factor, please start a different thread and not derail this one

If the goal here is to help people searching for information, to more quickly find the appropriate thread, then I completely agree - a new thread on the different topic is a better way to do things.

If anyone is concerned about "derailing my thread", that's different. Forum threads usually go way off track, over and over, and I have no problem with people taking my thread in a different direction (as most of the time I learn something new).

I already got a penalty for interrupting someone else's thread, so I'm real careful not to do that any more, but I have no problem with people doing that to my own thread. My preference, of all the ways this can be done, is to just leave a note in the original thread, with a link to the new discussion that was started as a result of discussions in the original thread.... That way everyone is happy.

 

[9mmepiphany]

That is the Staff's preference also

Well, I'd guess Mr. Leatham was not real happy with the stage shown in the
first vid. linked. He only had one "clean" pass on it, 4 of the 5 were six
shots.
Still a whole lot quicker than than I'll ever be......

Up to the first shot ammo ballistics do not matter.

Afterwards, more recoil means slower shot to shot times. Steel speed shoots have a minimum Power Factor of 125000. I.E. a 125 gr bullet traveling at 1000fps or a 200gr bullet at 625fps. IPSC also had a Minor PF minimum of 125000. The Major PF minimum has changed a few times but was probably 175000 in the era we started talking about. Obviously a 125000 PF is easier to control than a 175000 PF.

Back in the old .45 days we always downloaded for shoot steel. Then a typical IPSC load would be 5.7-5.8gr of WW231 & a 200gr H&G68 and for steel it would be more like 5.0gr (or less as long as it functioned) of WW231 with the same bullet for still well over minimum PF. This concept holds true today with the .38/9mm guns currently used. Some of the .38 Super/Comp etc. IPSC shooters will shoot 9mm for steel.

Then we can get into the discussion of gun weight. A heavier gun controls recoil better but a lighter gun moves from target to target better. Different folks have different opinions here. I know at one time Jerry Barnhart shot a steel gun built on a lightweight commander. The downside here is that it's real hard to hold the gun on target.

IMO this is really a complex subject that doesn't fit into a narrowly defined formula very well because you have to acquire a sight picture on multiple targets several times during a stage of fire.

Steel Challenge has no power factor requirement.

 

[1MoreFord]

I could have sworn it did but that was many beers and years ago.

 

[Ankeny]

Yup, they did have a minimum velocity. Hard to keep up with rule changes.

 

[g.willikers]

The Steel Challenge rules can be read and downloaded from the USPSA.ORG website.
The latest version, from 2013, doesn't seem to include any kind of power factor requirement.
For this discussion, in order to stay on track, how about if we include the .22 category.
Then recoil won't be a concern.
