It's my opinion that certain IDPA stages can be considered training, either self defense, law enforcement or another. Other IDPA stages are more clearly a test of skills which often leads to an increase in those skills.

The cover thing seems stupid to me as well. I can legally stand on 1 foot and stick more than half my body out, but that all-important big-toe had better not be exposed!
. . .It's commonly taught in law enforcement to keep the ENTIRE 100% of your body below the waist under cover. A shot-up toe may well put the good guy out of commission. Makes sense for self-defense too, the genesis of IDPA.

From a match administration chasing all the mags on the ground before someone else in the squad picks them up may be a problem.
I'm thinking possibly IronArcher means 3 sec per loaded mag dislodged all the way to the ground from a carry condition? What that rule's genesis is a means to penalize those who use ammo carry devices which don't properly retain; i.e. likely "speed" loose and not tight enough for all day carry.

Typical tactical training stresses keeping ALL your lower extremities under cover from unengaged targets. From a safety officer standpoint determining 100% of lower is relatively easy. Determining 50% of the above is a tougher but we seem to regularly do it without controversy.
One thought on leaving "good" mags behind containing ammo is that it would be a self correcting situation. Shooters would penalize themselves by running out of ammo before finishing a COF. Don't know if the concept has ever been tested.

As others in this post mention you need to base your PF off your LIGHTEST bullet in the batch and the LOWEST velocity. I'd suggest from a group of at least 10 rounds. For 125 PF under that premise I don't run lower than 129. For 165 PF around 170. For 105 around 113. If your current load is all over the place as far as extreme spread goes, I say work up one that has a low SD and ES.
Temperature and elevation as well as relative humidity affect PF. To keep that to a minimum i select powders that are relatively insensitive to these.
I've run the chrono at major matches where guys tried sneaking by. Some make it and some do not. It stinks for them.

Back before we could open carry in my long-time conceal carry state a number of us wanted some BBQ after the IDPA match. We left the gear on along with loaded guns and mags. We topped it with our vests. No BBQ sauce was spilled in the writing of this reply or at the BBQ joint that day.

Still looking for that replacement for 7625. Tried Alliant E3; takes 4.0 gr to make 130PF with a 125 gr HiTek coated in a Glock 19 with Lone Wolf barrel. Tried WST; takes 4.5 gr to make similar PF with same 125 gr bullet. Both are clean burning and reasonably cool. Neither are as accurate as 7625.
-
I remember hearing an interview with Hodgdon, they claimed 700X was the replacement, however, I used 7625 for my .40 loads and had no trouble making power factor, 700X would not without exceeding suggested max load. Now, that may be a different situation with 9mm.
700X is a pretty dismally dirty replacement. Not as accurate either.
-
Anyone know a near direct replacement for the recently discontinued SR 7625 powder? Pulling another powder off the burn rate chart isn't necessarily the fix as I am looking for a low burn temperature characteristic too, as 7625 has. My application is 9mm Luger with coated bullet. Other potential replacements, such as TiteGroup and Universal burn too hot; hot enough to melt through the bullet coating on its base.

This problem is not limited to IDPA. Most all range lawyer issues are resolved by simply referring to the CURRENT Rulebook. Too often range lawyers are remembering an older book. Sometimes they are trying to mix in rules from another discipline. Just go look it up in the current Rulebook.
A 30 min. delay on a match stage due to range lawyering is intolerable. The MD can resolve issues like this, with the complainants only, off to the side while the match continues.

Rule 4.11.4 says NT's may be painted or marked on the targets or may be clipped or stapled to the target.

Their answer is that it is normal wear. I sent them the same pictures as in the first post on this thread.
Is that "yes" to normal wear? Surely that's a typo on their part.Smith and Wesson responded to my trouble ticket today. Here is what they had to say:
Dear Customer,
This does look like normal wear.Smith&Wesson values its customers and we are happy to have served you today. Please do not hesitate to contact us should you require further assistance.
Regards, Ashley
Perhaps the Tech didn't see what you were trying to show. I'd suggest taking more pictures of both barrel and slide but tight on the problem area. I'd then suggest you try to go up the responsibility chain at S&W, maybe asking for a supervisor to review the images. What I am seeing certainly is not normal wear.

That's pretty ugly in the images. If S&W deems the problem warrantable you may end up with a new top end. If they think too much of the gun is toast they may replace it with a whole new gun.
S&W's policy for a new replacement gun is to send it to a FFL regardless of your state's laws on factory replacement of guns. If S&W is going to go the whole new gun route be sure to ask for your customer parts back quickly before the old gun is destroyed. S&W will enter a replacement gun as a factory order as ship it to your FFL when it's turn in the production list comes.

My Dillon brand sizing die gives me that desired coke bottle shape. There likely are other resizing dies out there that offer the same results. The important thing is to search for and maintain dies that produce this effect.
-
I am not advocating too much neck tension; I am strongly encouraging just enough.
The textbook method of determining correct TC for most cartridges is to measure the actual case wall diameter X 2 + actual bullet diameter then subtract .001". In 9mm (9x19) I subtract a bit more (perhaps as much as .002") to allow for the relative sharp taper of the case. When using mixed brass, choose the thinnest wall brand of cases for the diameter.
It is essential to do the "bullet nose push in test" with loaded rounds, those of the thinnest sidewall in the lot of brass being reloaded.
-
You cannot create neck tension by increasing the taper crimp. You CAN alleviate neck tension by over crimping with a taper crimp die but you cannot increase neck tension. There is no such thing as "crimping" a pistol bullet with a taper crimp die. They should have called the die by a different name. You are running a loaded round up into a wedge shaped die. Lead does not spring back as much as brass does so adding taper crimp beyond just simply getting rid of the bell and re-straightening the case mouth will reduce the front half of the bullet's diameter and decrease neck tension. If you are using plated or coated lead and leave a mark on the bullet, any mark, after taper crimping you are crimping too much.
Several would disagree with your comments. I will promise you that it is necessary to adequately hold the bullet in place during the feeding cycle to prevent telescoping back into the case. That is while not deforming the diameter of the bullet more than essential.
One additional means I use to avoid telescoping is a fairly tight spec'd resizing die. That die reduces case resize diameter to the point that the base of the loaded bullet is visible in the cartridge. Some would call it the "Coke bottle" shape.
-
Be very careful running 9mm Luger with too little crimp. The bullet can telescope back into the case upon feeding into chamber. When fired this produces a high pressure condition. I prefer to run a taper crimp nearer .376" for safety. You can test for adequate TC with a particular bullet and case brand lot by pushing a loaded round against a surface with moderate single hand pressure. If the round OAL shortens that's bad. .375" or tighter will produce an accuracy decrease because bullet diameter is being swaged smaller.

I am not experiencing any bad results with coated vs plain lead. I observe much less lead "smoke" with coated upon firing. Did not have good luck with TiteGroup powder. It burns really hot, hotter than most anything else I use, and seems to melt lead off the back of both coated and plain bullets. Other powders do not have this effect on coated.
Has anyone tried Winchester AA Lite with coated lead in 9mm? Any data to share for a 125 gr?
-
Has anyone tried Alliant Extra-Lite powder in 9mm with a 125 gr coated lead bullet? I am look for results and data, if that exists. Its a fine powder that should meter well in measures.

BTW check your Nationals Points as reported back to you by HQ. They had mine wrong as well as at least a couple others in my local area. Clerical misadventure I suppose.

A gable roof will have much less blown in moisture up into the roof rafters and purlins than will a shed style roof, I imagine.

Eastern Oklahoma. Not as windy as Western, but still plenty windy.
As far as insulation, we're considering adding spray-on to the underside of the metal IF there is later discovered a problem beyond what normal ear protection will handle.
We really only expected to get 90 mph trusses, as that is the required spec. We're getting 120 mph ones for the same cost, probably having to do with only spanning 16 ft. I also asked for trusses with a minimum bird nest locations. Truss designer came up with 2 x 6's.
A neighboring county requires hurricane clips; we will probably add that to the spec. The cost will be minor.

Range faces North. Most really bad weather comes from Southwest, but occasional 100 MPH gusts fronts come the North or Northwest.
The pricing I'm getting shows gable as only slightly more expensive. That's using 120 MPH pre-engineered 2 x 6 treated wood trusses. Truss cleats will be either SS or G155.
One of our primary reasons for considering gable is to lessen wind effects. A flat shed roof acts as an airplane wing, thus accelerating winds underneath in the bench area. Tough to keep gear on the bench at times. This same lift effect seems to make a flat shed roof more susceptible to getting ripped off in high gust wind events.
As far as insulation underneath, any specific product suggestions that will take getting wet from heavy blown-in rain and won't be attractive to bird nesting activity? The insulation materials we've considered have not been suitable.
We know that noise is a trade off with comfort, this in relation to height specifically. Will 9 or 10 ft vs. 8 ft height be that much quieter to someone wearing proper ear protection.

You might want to look into replacing the plastic mag bases with metal ones. Metal should be thinner and might solve the fit issue. No, I don't know if HK makes such an animal. They might for military or other extra hard use purposes. Remember that same mag also fits the P30.
