I have the Magpul coupler. It allows and the instructions recommend an offset setup, which I have used w no problems.

You can actually buy the stand alone Hornady seating die and their micrometer stem. Cheaper than the Redding, and you can swap the stem between other Hornady seating dies cutting cost even further.

Not sure what kind of dies you use - my 38 special sizing die has a small ring of carbide and sizes cases straight, but none of my 9mm dies do. Both my Hornady and RCBS have TiN and Carbide rings that correctly size the cases to spec (i.e. Tapered). I would imagine yours do to - not sure how you could straight size a 9mm case - the mouth has to be about .355 if you are going to have any neck tension, and that would crush the base of your case.And if his cases were bulging in the case web (where chamfering is done) he'd probably be having bigger problems. Like tough extraction or a blown up gun. You were right about Dillon dies being the likely cause of the issue though. So there's that.

He certainly can ask. But he would need to ask the manufacturer.

Because no one ever buys a custom gun and has problems with it running out of the box? My 3 STIs have all run out of the box. My only race gun issue has been with one MBX mag, and that got fixed quickly. I blame some on shooters who buy an STI and immediately change out things like the extractor (because "everyone" knows they don't run from the factory) to an Aftec but don't bother to fit it. And on and on. I'm guessing some of it is shooter dependent and some spotty QC, but unless you're getting a Glock there's always a chance you'll have an issue.

Why would you jump to the conclusion that your measuring machine is wrong? Let's see, the first shot. You probably chambered a round, brought the gun up, and pulled the trigger. Powder will be distributed differently in the case than it will on subsequent automatically chambered rounds. Try holding gun muzzle up or down and bringing sights up the same way before every shot. If the first shot is from a cold barrel and the next four are not, there's another discrepancy in what you're trying to measure. That should be enough to get you started.

Mine has been great - I wish they made one in .40 too.

A lighter bullet with the same momentum (Power Factor) as a heavier bullet has more kinetic energy. That extra kinetic energy comes from more powder. This is a lot of magic hand waving and doesn't really answer the basic question.

I just can't.

I showed it is dangerous. If someone sits down with the spreadsheet, a goal velocity (say 1150 FPS) for a given caliber (9mm) and bullet (147 GR), a pound of N310, and a chrono, they will blow up their gun before they reach the max velocity that the spreadsheet shows would be reached at max pressure for that round. Basically what the OP did trying to make major in 9mm with Titegroup because the spreadsheet gives the illusion it's a safe endeavor. As for your ignorance of Quickload, that's something well within your power to resolve.

As usual, you have no idea what you are talking about, but you insist on going on and on. 3N38 is one of the slowest powders used for 9mm. Not really a great example to use here as it provides the safest margin for error. Also, in actual testing by VV, pressures do not exceed 35K PSI (unless you believe VV would like to be sued). Let's go to the opposite end of the spectrum. Using quick load, a 4.4 GR charge on N310 would give you the same velocity with a 147 GR XTP. However, the peak pressures (in excess of 75K PSI) would likely lead to spontaneous disassembly of your firearm. The spreadsheet is not on the safe side of the fence, in fact it's not on any side of the fence. It's firmly out in fantasy land, outright dangerous, and likely to hurt anyone ignorant enough to depend on it.

Yes, the linked page has a spreadsheet. It makes calculations based on parameters. Quickload does the same thing. However it takes into account certain key parameters that this spreadsheet completely overlooks. For example, Quickload takes into account cartridge OAL and bullet length to understand the starting volume of the combustion chamber. It also takes into account energy density and other characteristics of the powders it models. Whether bullet is lead or FMJ. And more. I could give you a load that will make 35K PSI in 9mm but not make the estimated velocity from that spreadsheet, and a load that would make that velocity but would blow up your gun in the process because pressures would exceed 100K PSI. It may be an acceptable model for a specific powder over a narrow range of charge weights, but fails as a general model and quite frankly should be caveated or removed before someone relies on it. You simply cannot create a general model independent of propellant. I'll give you an edge case to prove that: how many grains of N310 to make 35K PSI in 9mm with a 147 GR bullet. Use that spreadsheet to get the velocity, then go ahead and work up a load over a chrono and let me know how that spreadsheet works out for you.

This. Quickload is proof that there is serious math involved in what this spreadsheet pretends to do.

Like I said, Fudd stuff.

Bullets off of poppers, plates, or the ground aren't typically going to have the velocity to make it far or the energy to do any damage.

I know in my area a lot of ranges are converting to "no blue sky" style setups due to bullet excursions - either at the affected range or due to an occurrence nearby. It's expensive, but most ranges are well funded here - I could see it shutting down smaller more rural clubs. That said, these excursions are generally the result of idiots being idiots - I think draws and reloads are the least of problems for typical ranges. Even if reloads are the most typical way a round goes over a berm at USPSA matches it makes sense to remember that most folks shooting USPSA are head and shoulders above most typical shooters on safe gun handling practices. This is just more Fudd shit and best dealt with by DQing offenders.

I took quite a bit off mine. I still ordered a welded lifter as insurance even though I haven't caught my thumb since working on it.

For 3 Gun? /Metalform or Dawson Precision (uses Metalform as OEM)

This is completely inaccurate. The NFPA publishes model codes that municipalities MAY adapt IF THEY CHOOSE to do so. If your municipality (or AHJ as anyone familiar with the NFPA would refer to the authority having jurisdiction) doesn't have any codes, then no codes are in effect. The NFPA is a trade association and has no ability to set rules or regulations at any level.State, County, and Local ordinances can be as restrictive or unrestrictive as they want. Period. Next you'll be telling me how if your house burns down and you have too much powder your insurance company will deny the claim.

They list the same load data for 9x19.

Is this thread a joke? I clean my Glock 34 once a year. I add a little lube once in a while. 2014 was the last year I regularly shot it. About 8K during the season w no cleaning.

You're assuming that they randomly decided to use bulkier and more expensive packaging despite having a financial disincentive to do that. Folks like federal primers because they're easier to ignite. Primers that are easier to ignite require greater physical separation to prevent sympathetic ignition if one primer is set off.

No, it doesn't. There is a rearward force exerted by the case on the breach face, and a forwards force exerted on the barrel by the bullet. Those forces are equal until the bullet leaves, at which point recoil begins.How does your theory explain the function of blowback pistols? In a blowback design there are no locking lugs and the barrel is rigidly attached to the frame. It's not a theory, it's physics. In a blowback gun there is a rearwards force against the slide. Because the slide is not locked to the barrel, and the barrel, attached to the frame, is being held by the shooter, the slide begins to move immediately, with movement damped by slide mass and spring weight. With a locked breach firearm the rearward force on the slide is cancelled out by the force on the barrel because they are locked together. You may want to watch the above video before you dig into your position that the slide doesn't move until the bullet leaves You should read my whole post first.

Those forces are equal until the bullet leaves, at which point recoil begins. In practice, a little gas blows by the bullet and adds net rearwards force but the practical impact is minimal. The second pic is most likely embers / flash as others have noted.
