Ran across this article online. It seemed to be an interesting take on research into "being in the zone".
Knowing the deep and abiding interest around here with shooting in the zone, I thought some of y'all might find it interesting (or at least amusing
)... The far out thing was the concept of using tDCS on certain parts of the brain to provoke a zone state. Not sure I'd be willing to let them hook up electrodes to me and pass a current across my brain just to improve my score but... -
Where are you located?

Where in alabama are you located?

Green... It looks brighter to my eyes.
In addition like the guy above I am normally an open shooter so I find red triggers the dot on target break shot reflex.

Check with dt1 on this board he runs this kind of match at steel city here in birmingham 2-3 times a year in months with 5 saturdays.

So if we want non-reciprocating front sights how about a non reciprocating rear sight as well? My high standard victor has a rail that attaches at the front that carries both sights. The slide is flat topped and fits underneath. Or maybe a bracket of somekind that attaches at the back of the frame that carries the rear sight. Or maybe a full length rib that attaches to the dust cover like a c-more that carries the sights... Then you could have as long a sight radius as you wanted without caring about the lengthy of the slide or barrel.

I use the wolf springs in my old style caspian mags.

Yep... Shame about the recticle though.

Find one of the german police trade in H&K P7s. They generally have good triggers and shouldn't be that expensive. (maybe a bit large though depending on the intended carry method.)

Might check the diameter at the back of the cases in question, I believe that the 9mm being a tapered cartridge is a bit fatter at the back. I had an open gun once that was originally chambered in 9x21 then was re-chambered to .38 super if I remember right it worked fine but the brass got bulged a bit at the back. I have a casepro so I could roll the bulge back out but might be something to think about.
Maybe it could be reamed to 9x23?

I am dropping Robert's and mine in the mail tomorrow.

Neil Keller would be a good choice (he is in decatur,in). He does great work.

Probably not the full story... http://en.m.wikipedia.org/wiki/STI_International
I guess you could always call virgil and ask him.

Does converting 38 Super STI magazines to 9mm Major magazines just entail adding a spacer? If so, are you not also required to change the follower and spring to a set that have a narrower breadth, to allow for the spacer?
If all of the above are true, would changing the internals on tuned magazines affect the maximum loading capacity with the new caliber? In other words, after the conversion will the magazines still achieve maximum capacity?
Any feedback would help.
Yes you probably need spacers. I like the steel "Joey Hardy" ones you can get from Shooters Connection. As you suspected that calls for a different follower. I prefer the grams fks-11 or 13 spring and follower. There are reports of old style SV mags running 9mm without spacers but I haven't tried it.

"The stack can't start to move until the rail on the bottom of the slide comes clear of the top bullet in the stack, once that happens the slide continues to move rearward for a short distance before it bottoms out and starts moving forward." --caspian guy
Thanks, i was under the impression that once the top round is stripped out on its way into the chamber, the next one was already on its way up. I didn't realize that the next round stays down in the mag until the slide passes back over it in its rearward travel. Just does not make sense to me. I realize that it prob. takes longer on double stacks, but is this a problem that happens often? just trying to picture what part of the gun keeps the next round down until the slide goes forward and then back again.
There is a rib on the bottom of the slide in most self loading pistols that holds the top round in the magazine slightly depressed when the pistol is in battery. If you take the slide off, flip it upside down and look at the back section on the bottom behind the breach face you will see it. To watch how this works take a mag with a single round in it. Insert it with the gun in battery with an empty chamber. First thing to notice its that some effort its required to push the mag home till it locks in. That comes from the rib pushing the round down and compressing the spring. Next while watching from above the ejection port, slowly retract the slide and watch what happens.
-
Only thing i really don't understand or agree with (could just possibly be from lack of understanding) is why you want that slide to stay open for so long. Seems to me you would only want it to stay open long enough to safely eject the casing (not come back and catch it) Your reasoning in the video was that if it came forward too quickly the next round would not have had enough time to rise up into the ready position to be stripped from the magazine, and that the slide would pass over it, but the way I understand it (or at least how it seems to work in my guns) is that the next round rises into position the instant that the one above it is stripped and would already be in position by the time that the round was chambered and definitely before the round could go off, and slide make it's rearward trip and then start forward. Could you please explain this a little better. I'm just learning and trying to understand all the info this forum provides.
Physics dictates that it can't occur instantaneously... A simplistic view of the forces at work are: gravity acting on the mass of a full stack of bullets, the friction those bullets have to overcome as they start to move (due to contact with the inside of the mag body). The force to overcome that comes from the mag spring. The stack can't start to move until the rail on the bottom of the slide comes clear of the top bullet in the stack, once that happens the slide continues to move rearward for a short distance before it bottoms out and starts moving forward. When the breach face of the slide comes forward even with the rim of the case the top round in the mag must be in position. The motion of the slide dictates a short window during which the force of the mag spring must accelerate the stack of cartridges up the mag body to get them in place to feed.
many factors can impact this:
strength of the mag spring, smoothness of the inside of the mag tube (seems to matter more for double stack guns), length of slide stroke (e.g. if you added a thick shock buff).
It all boils down to F=M*A...

Mine shoots about 2 moa if I do my part with surplus m80 ball. It has the stg58 barrel in it and dsa did a trigger job on it when I bought it.
Vandenberg custom (vandenbergcustom.com) makes a very nice muzzle brake for the fal.
Ed also works on FALs as well should you need some smithing done. (ed also sells a nice free float tube)

They did make an aluminum grip saftey and an aluminum msh, not sure if they still do.
Which version of the mags are you using? I wonder if the old style is any lighter?
You could probably lose some weight out of the front strap as well (maybe slot it internaly if that is allowed dont know what the rules say about that these days so best check first).

I believe the guy that built my guns suggested federal or remington. I have always used federal for a preference.

The reticle for this scope has been added to the Strelok Ballistic Calculator (https://market.android.com/details?id=com.borisov.strelok&hl=en)
I thought it was very cool that the developer of the program added the reticle after I made a donation to his program and requested that he consider adding the reticle. May not be that helpful during a match, but it's still cool!
Steve
Thanks for the heads up Steve I just updated the version on my phone.
I had intended to talk to him about adding it after I got the data for the reticle from meopta, but just never got around to it.

Depending on how long those big sticks are you could mill out the dimples at the bottom of the mag and get an extended base pad from egw. That would probably get you up to 28 rounds. You'd have to check with it a gauge to make sure it was legal, but I was using a weld up mag from Fred Craig that I had modified as I described until I got one of Jim's.

Both of my guns started out life as 38 super. One was converted to 9mm with a barrel swap, on the other I put on a new top end to convert it to 9mm. In either case My mags (old style) work with either 9mm or 38sup with no issue.

Hello: Looks like alot of dot movement to me. But then again I never have used a high speed camera to film the dot on my 9mm open pistol. Just using my own eyes and a couple of others who have shot my open pistols say the dot does not leave the glass. It looks like the dot is doing a figure 8 a little bit also. That may be your grip causing that or the powder. I know when I have run the power factor up with 3N37 in 9mm it does that figure 8 motion. Good looking video
Thanks, EricI've yet to slo-mo a dot that didn't leave the scope, no matter what it looks like to the naked eye.
Figure 8's and loops and such are quite common and usually grip/stance/timing/flinch/push-related.
Here's one of me shooting a plate rack at 600 fps.
Shred,
What kind of camera did you use to capture that video?

Yep... I think quite likely you are correct.
