From NROI ruling:
Created: 9/19/08
Updated: 10/16/08
Effective: 10/23/08
Rule Number: 9.1.5/9.5.2
Applies to: General
Ruling Authority: John Amidon
Status: Released
Question: Target array is a no-shoot over a scoring target. The top of the NS head directly covers the bottom half of the lower A zone, with the lateral non-scoring lines of the NS *directly* over the A/C zone scoring lines of the scoring target. How is this scored?
Answer: In accordance with Rule 9.1.5, the scoring areas of scoring targets and no-shoots are impenetrable. Whenever two targets (scoring and/or no-shoots) are in direct contact where one target directly overlaps part of another target, the area of the "under" target which is directly covered by the scoring area of the "over" target and its perforations is deemed to be non-existent. Additionally, Rule 9.5.2 is clarified to apply only to the visible portions of targets. It specifically does not apply to any area of any target which is in direct contact with and overlapped by the scoring area of another target (scoring and/or no-shoots) or by hardcover.(Edited for format) -
Update.
Measured the chamber. It is only .734 deep and it visibly protrudes past the hood. I will update again once I have resolution. Hopefully this will help a fellow DIYer.
So you are about .020 short on the chamber, that sounds like you have 2 issues. .020 short should not hold you out of battery by 1/4".

Brain farts never help either. I shot a match on Saturday and the first target array was two white no shoots butted up against a normal tan target at about 7 yards. Buzzer went off an I fired a perfect "A" hit to center mass on the left no-shoot. Shot the rest of the stage perfectly. When asked what happened I explained it was just a brain fart I actually aimed for the no-shoot by mistake. Oh well.
Because you looked at it... BTDT
(Ignore the no-shoots, focus on the shoot targets, even if it is surrounded by no-shoots. (i.e. when planning - I have this much of a target. The sub-conscious ignores negative qualifiers.))

It could be a feed ramp issue. I think I've heard it referred to as a 3 point bind.
Could very well be this, normal fix is breaking the edge at the top of the ramp where it goes into the chamber. (Do you have Jerry Kuhnhausen's Shop Manual? It is a very good reference.)
I will check those items.
I've been thinking about this while at work and I remembered that the barrel hood had to be cut way back. The EGW gauge on the shortest edge would not even fit into the slide. I'm wondering if I have a headspace issue?
Do the rounds sit (just under) flush with the hood? You said they chamber checked, if they really did, then you shouldnt have a headspace issue...
If they drop in correctly - no (as DWFAN states).
-
Take the top end off, spray some Kroil on the bushung to slide joint, (from inside also), allow it to sit for an hour or more and try again.

When you are reloading the most important safety advice is attention to detail. Also see if you can get a buddy who reloads to show you the ropes and help you set up your new machine. As Hi-Power Jack says start low and work up.
-
You have a 1911? If so start with that.
If you don't want to start with the 1911, and the grip angle on a 1911 fits you then consider an XD or XDm (same grip angle). See if you can shoot some of these at a local range or after a match to try them. (You want one that fits your hand.)
-
Have you tried Airsoft? There are examples of Airsoft plate racks on here, and you can get or make a Airsoft texas star.
As for the trigger reset, practice dryfire by cycling double action, hold the trigger back, cycle the slide and reset the trigger slowly.
(The double action trigger is really good thing for dryfire also.)

Glad to hear that you are doing well.

From USPSA Multi-gun rules (Disqualification Unsafe gun handling)-
5.3.19 Firing a shot at a metal target from a distance of less than 23 feet with a handgun, 147 feet with a rifle, 23 feet with a shotgun when using birdshot or buckshot ammunition, or 147 feet when using slug ammunition. The distance is measured from the face of the target to the nearest part of the competitor’s body in contact with the ground (see Rule [10.1.3]).

That would depend on the firearm, Para-ordanance LDA - hammer follow OK, standard 1911, 2011, or standard Para Hi-cap not acceptable and unsafe.

More grip contact on the weak hand = more control (assuming same grip pressure)
The pressure you are using on your weak hand that is on your strong hand doesn't have as much effect (picture as if it were 2 sliding surfaces), the pressure on the grip is
proportional to the weak hand grip, however the sliding surface (your strong hand) doesn't transfer all on the grip pressure to the gun, some is used conpressing the strong hand.
Grip pressure / hand strenght is critical, locked wrist maybe not so much. Read the posts referenced in Post #6 they will help this explaination.
-
You want as much weak hand contact on the grip as you can get. The angle of your weak hand really is dependent on your hands and forearms. Try several varying angles, contact pattern, and grip force til you find what you are looking for.

Possible problems:
1, Insufficient sear spring tension, (right leg) Obviously if it's too light, it can cause problems.
2. Insufficent sear spring tension, (center leg) If this is too light, you can get trigger bouce. Confirm by holding the trigger fuily back while releasing the slide stop. If the hammer does NOT drop, then it's trigger bounce.
3. Insufficent trigger pre-travel.
4. Poor sear/hammer geometry. Obviously a poorly mated hammer and sear can result in this problem.
1 and 2 are fairly easy to test, just bend the legs on the sear spring forward to increase the pressure on the sear or disonccector/trigger shoe. The left leg controls sear pressure, then center trigger pressure. If there is too little pressure on the trigger shoe, you can get trigger bounce, which causes the hammer to fall.
3. will also contribute to trigger bouce. Too little pre-travel will give the trigger less distance to travel and if the center leg of the sear spring is too light, it will 'bounce' more easily. Adjust the pre-travel by bending the two tabs on the front of the trigger bow in or out. Proper pre-travel is at least .025" or your half-cock notch won't work.
4. Unless you are experienced and have the proper tools, you shouldn't even attempt to mess with this. Take it to a gunsmith.
This^^^ is a really good description.
To test for the #4 cause try walking the hammer off (grab the sides of the hammer with it cocked and the gun empty and move it sideways several times and forward, if it comes off the sear the geometry is wrong which normally requires a new sear and or hammer). Taking it to a good gunsmith is recommended.

Honestly both new grips do a little. I'm thinking it's just because I haven't developed the muscle memory yet. The less aggressive grip has less of a problem but for some reason it's harder to get into and doesn't naturally line up the sights like my original grip or the more aggressive grip.
The problem seems to be my hands being too big also, that combined with figuring out weak hand grip pressure. Does the less aggressive grio look right? Would it be better to go back to the old grip?
The less agressive grip has more weak hand contact which is good. The fact that it doesn't naturally line up the sights means it is not neutral. The shifting sounds like a strenght issue.

I have a stand alone machine in mind, just had to have something that worked for me right now.
Cool, I have a couple of ideas also, will have to see how they compare. Mine will probably be a while though, working on a motorized trimmer right now, details will be posted when I get it finished (final parts are still about a month out).

I recently realized that I've been using an incorrect grip. I working on retraining a more "thumbs forward grip" I have a more aggressive and a less aggressive grip. The more aggressive grip feels more natural and more stabile but my palm doesn't contact the grip on my weak hand too much. The less aggressive grip gives me a lot more contact on my palm but it's harder to maintain a hold. Also the more aggressive is slightly more accurate but the pistol shifts a lot in my hand between shots causing me to readjust.
Which is more correct?
If firing the gun is causing your grip to shift then it is not right for you.

There are very few of the of the worlds problems that can't be sovled with the appropriate charge of explosives
Don't know where its from but I heard it with 1st EOD plt camp pendleton
"Most human problems can be solved by an appropriate charge of high explosives." Blaster (Reb Brown) from Uncommon Valor
Also "Any problem on earth can be solved with the proper application of high explosives. The trick is not to be around when they go off."

My open gun has holes that touch land and grooves, it will shoot 1" groups at 25 yards. Are you really going to be able to utilize better accuracy than that? If not then there is no difference. (I do not know if there would be any measureable difference if you managed to make sure you only touched the lands with the holes, I am saying does it matter?)
-
Looking good.

Sounds like you took it with honor and learned from it.

.380 to .40, the only common part is the small primer feed. A .40 cal conversion kit and a quick change kit are what I would recommend.
Can't get a good Taper Crimp on 9mm 115Gr RN Xtreme Plated bullets
in 9mm/38 Caliber
Posted
9mm or others, doesn't matter. Case tension holds the bullet, not the crimp. The case needs to be sized small enough to grip the bullet tightly. On a tapered case this means the sizing die adjustment is more critical, it must fully size the case.
