The NRA range book is useful so you can tell people like insurance companies "it's built and run to NRA standards like police ranges are" (you'll also want to hit up the likely insurance prospects like Lockton to see what they want WRT berm height and posted rules and such) Get the $20 USB stick instead of the giant binder-- https://materials.nrahq.org/index.php?route=product/product&path=91_113&product_id=405. Has lots of general range things not very relevant to USPSA / Steel bays, but a few things that are.

There's a reason for those tooth-rattling loads-- they need that much gas to work. Lightest bullets and most powder is the recipe for 'flat'.

still on the .40 ejector?

I think the yellow "cornmeal" is not unburned powder, it's some sort of combustion residue. I saw that a long time ago in an Open gun. Scrape some into a little pile and see if you can ignite it.

Get a 10x loupe or magnifier or phone or whatever and look at the gap between case and bullet with magnification. If there's an obvious gap (bigger than maybe 1/4 of the brass thickness), you need more crimp. That said, it's very unlikely to be the source of your unburned powder. Btw, is it actual powder flakes or yellow cornmeal stuff or what?

Eh, VP wanted to know what my Aluminum pads weighed before he'd give them the nod. Brass was of course, right-out.

That amount of crimp also doesn't matter for accuracy. It swages back out with 20K PSI pushing on the back end.

Maybe he did a review of it, would be interesting to find the article. I've got Briley's catalog cover gun from a couple decades ago, although it looks a lot different now.

Mitus feel a lot better to use, but for reloading most any work well enough.

Factory basepads are stamped from steel on many mags. Also slap on enough aluminum and you can make it kind of heavy. Pretty sure IPSC doesn't want that.

Yeah, there's a decimal out of place somewhere I think. An overly-tight extractor will stop closer to 1/4" out of battery and it'll do it easily by hand when racking the first round in (anything but "yank back and let-fly" on the slide)

Weight distribution matters too.. same weight in different places will transition and recoil very differently...

How far is it stopping short? If it's extractor tension you should be able to replicate it by slowly racking the slide.

That's been an open question for at least a decade ever since I started making basepads in 2014 and asked for a ruling

SIG's "GSR" from 15 years ago stood for "Granite Series Rail" IIRC. They're not-new to breaking from tradition if they want to. But, just like 45 is by far the most common 1911 caliber, by far most of the pistols in the case at the gun store just have iron sights too. I'd bet a 10mm is on the roadmap. Seems like it's the trendy single stack now.

I'm going to shut this now, following the guidelines; The OP can PM if desired to reopen for some reason.

Seems like a really easy argument to make in court-- "so Mr Police Training Officer, how many of your cadets have rule violations during training and qualifications?" "and you still let them carry guns on the street?" Sounds more like some do-gooder at the club has a thing against 'unsafe' USPSA shooters and thinks throwing them under the bus will help, but the whole point of the rules is to try and stop things from getting truly unsafe well before they do. Some dude is a serial DQ-er, sure tell them they can't come back to the range if that makes them feel better, but reporting ???

Not all of them. Some are made on 9mm slides that won't fit a regular .38 Super.

Yes, extractor-change if it was made on a .38 Super slide.

The usual advice is "don't carry handloads" Has that changed?

The mag catch is in a slightly different place, so assume "no". Also Para (& RIA) mags with the steep top usually get an extra round on board. There are STI-for-Para mags and tubes around with the slot relocated, but I'm pretty sure none have been made in at least a decade.

Same here, I'm something like a 50 % M in Revo because of one classifier match long ago.

Those Husky shelves are bombproof and rock compared to the particle-board shelf ones.

I've been happy to not find any 9x21 or 9x23 in with my range pickups lately..

no "race" holsters unless you wrap a fig-leaf of Kydex around them. No dots, no comps.
