People don’t have two page discussions about guns running as expected. We only hear about the problem children. And 2011s are 90% of the open gun world, so volume alone dictates the most complaints.

Flat out wrong. Come chisel the coating out of my comp, and I do literally mean chisel, next time. I always rolled my eyes at the Open princesses who shoot JHPs presumably because they’re too lazy to clean. Except it’s not merely “cleaning.” I gave up hammering the concrete of welded-on hi-tek coating out of the thing with a chisel, and just ground it out with a carbide burr in my dremel. Even FMJ’s exposed base still leads your comp. Mine only gets plated bullets (cheap, no exposed lead and no coating) now. After 1,500 rounds all of this came out of a little old 9mm compensator!

By my way of thinking, you didn't do a *full* plunk test: I want to know exactly what length causes that bullet to engage the rifling. I'll load at 1.160" and it'll fail to spin freely in the chamber. Try 1.155" and it fails. Continue shorter until it finally spins freely. By this method, I'll know in a few more repetitions that a specific bullet will contact the rifling at, say, 1.135-1.140" I'll then make sure that my press doesn't produce any ammo longer than 1.130" for this example, so that I have .005" of wiggle room. That means than my old 650 would be set up to crank out ammo that varied between 1.122-1.130" in length. It always had around .009" of variation, and it's important to account for that.

As the original poster, what made me laugh was they turned around and sent me 100 more of the same shoddy batch with missing coating in an attempt to make it right. Thanks, Acme. Customer service left a little to be desired. I’ve had much better response from companies like Bayou and Black Bullets. They’re top notch.

Open M&P. The only way to ensure a more frustrating experience than Open Glocks.

Extreme bullets are overpriced for what you get; they’re very lcose in cost to the bulk price for the muh higher quality Precision Delta jacketed round! I like the feel of a 124 through a Tanfo much more than a 147 but that is a subjective thing. BBIs run great with a reamed tanfo barrel; if you weren’t going to ream it I’d have suggested a .355 coated bullet like the Blue bullets. For an alterantive in plated? Everglades are extrmely high quality and I currently run those in 124... coated isn’t an option for the PCC’s comp. Rocky Mountain Reloading’s bullets are getting good reviews on here. If price is the key factor? Blue and ACME are cheapest in bulk, unless you have a local hookup. The CEO of Black Bullets lives here in town, so I get a discount because he doesn’t spend a dime to ship and they’re right down there with Blue bullets.

I hate to be hard on you here, but if you find a ballisitics calculator and do the math? You’ll like find that your POI/POA shift is so small at 30ft that you’re going to have a hard time blaming anything other than visual patience / trigger control. You might get outside the A-box in the head if your POI was offcenter, but you aren’t missing a 6” square at 30ft altogether just because your bullet weight changed.

Titegroup and coated leave your gun filthy, but runs great and is cheap. You’ll wind up at 3.0-3.2gr titegroup with whatever length plunks & spins in your barrel. A coated bullet that measures .356” is going to need to be seated very short to feed in a Tanfo. I highly recommend getting your barrel throated with a finishing reamer designed for polygonally-rifled barrels, so you can run any bullet profile out to 1.150+” that you want. PatriotDefense can do that, and so can I for that matter. 9mm cases are thin at the mouth for .300” of depth. Deeper than that the walls grow thicker, so seating a long 147gr bullet down to an oal in the neighborhood of 1.090” - 1.100” can result in the walls bulging and your most work brass failing to case gauge. Either ream the chamber to load longer, or switch to a lighter (shorter) 124gr bullet.

@Jollymon32 when you got home did you do a plunk & spin test to see if something had somehow changed and your round were all getting hammered into the rifling? Or was that one round insufficiently seated somehow, and longer than the rest? For what it’s worth, everglades plated 124s are fairly reasonably priced and my guns like them. Their shape is also short-barrel friendly and you don’t have to drive them back to 1.090” to run in a CZ or the like.

Same here. Very much I would have saved up, or sold the neighbor’s children, and went directly to a 1050. Oh. Wow. That was obvious.

Unnecessary. If you run a 650 correctly you might as well remove the ramp. (1) keep a box of a few dozen sized and deprimed cases next to the press. If you pitch a torn case out of the shellplate, put one of those in the second station when needed so you don’t have an empty shellplate, and it won’t spit out a primer. OR (2) Learn to lift the primer ratcheting arm as you raise the shellplate: Each time you cycle the press a chrome metal arm hits a black ramp on the press frame, indexing the next primer. If you lift that arm upward with a fingertip as your shellplate moves upward, it won’t feed the next primer... it’ll use that same primer on the downstroke after the next case is presented to it. I never had any widgets on the ski jump. I never had primers on it, either. Learn how the press works. Best option: (3) Upgrade to a 1050. It’ll continue to present the same primer for 100+ press cycles until a case arrives and finally takes it. Then it’ll feed the next one.

The one I bought before it that routed down through the table always ended up kinking and clogging.

@Jamese35 in 9mm the crimp die... doesn’t actually crimp. It’s more of a “flare removal” die that resturns the brass to straight. 9 is a taper crimped round, versus the roll-crimp that a cartridge like .38 Special uses. I run a Lee U-die in station 1 on my 1050 even though I don’t own a wheelgun. It sizes the brass down an extra .002” or .003” and really helps EVERYTHING pass the case gauge. Neck tension is what grips the bullet in 9mm, and it greatly increases that as well. Also highly recommended? The powder funnel made for the Mr Bulletfeeder by DAA. It shapes the case mouth for a bullet to be placed in a much better manner than the dillon powder funnel’s “trumpet flare.” I recommend one even to people who don’t run a bullet feeder on their 650/1050.

He wants a PCC that shoots smaller groups than most do at 50+ yards. Which means you money will be best spent on a high quality JHP like a Zero or Montana Gold, perhaps a chnage of barrel, and a lot of load development. And not on a specific magical crimp die.

So I can weigh in on this... I shoot a Walther POQ with a heavily lightened slide in CO. The DPP weighs 1.9 ounces, and I’m still 2 ounces lighter than a factory slide with it added. The 4” PPQ is a “fullsize” which is roughly the size of a Glock 19 in terms of grip size, but with 1/2” more barrel length. I managed to get 5oz of weight into the backstrap with some tungsten weight before doing epoxy & grit to the grip, so it’s a wannabe limted gun. Heavier frame, lightened slide... but still under 30oz. The recoil is snappy. Most other guys with buttery soft heavy guns? Immediately remark on how fast and sharp the recoil impulse is. The dot movement REALLY lets you know if your grip isn’t at Fully Crush Grip status. Much moreso than iron sights do. But she shoots:

@JAFO my mistake. I didn’t realize we were taking about Troy’s convoluted interpretation. I thought we were talking about a common sense interpretation of the obvious meanings of the rulebook’s terms “creeping” and “false start.” I think a shooter delibrately and obviously crawling toward the gun in hopes that match officials won’t notice... Absolutely deserves a penalty. A shooter in the proper starting position reacting to (what sounded like) a start signal, does not. But there I go with the common sense again.

@Hi-Power Jack which is funny, because that is the textbook definition of false start. As has been mentioned, only slowly sneaking yourself into something like a “less surrender start” or “arms relaxed at sides” qualifies as creeping. 90% of issues at the beep are merely false starts. Yell “STOP!” as they clear the holster, and start them over. We’re there specifically to make sure everyone starts in a position which complies with the phrasing on the WSB, no more and no less. Be consistent, and don’t be a dick.

Yes, but not compared to a glock slide if it were cut so deeply that your optic is the cap for the exposed striker channel. Gotta get balls deep, son. Ball endmill I meant, of course. I had a PPQ cut instead of my Q5 because Mark at L&M precision said he could get it at least 1/8” lower without all that optic mounting plate mumbo jumbo in the way.

You go CO, and I’ll switch back to my PCC. Long guns are just less frustrating to shoot with half-frozen hands.

@Explosiveo spending money is what this sport is all about. Not shooting. You need a DPP slide, and an RTS2 slide, and...

@robchavous my goal is... not to. Literally holster up a production gun and shoot it ‘2nd gun’ in our matches back to back. I don’t see any reason you wouldn’t want to effortlessly switch to irons on a carry gun, or different competition division.

I’ll counter the above. I have my walther cut so deeply the DPP is riding in the top of the firing pin channel. It’s so much better than my adapter-plate Q5Match that the Q will stay irons forever. Mill it, and mill it balls deep. Life is so much better when you want to go back to irons, or switch back and forth.

This will prove helpful. Max wins nearly every USPSA match he enters:

Stop. Just stop this, dear entire internet. Please. This isn’t the Delicate Gun-Owning Flower’s forum on Facebook. We believe you’re a mature adult, with no need to be swaddled in a safety diaper while he handles firearms. The fact that everyone on YouTube feels an obligation to show a clear gun at length in every video is very depressing. Common sense implies it will be unloaded. If you’re dumb enough to handle it loaded, well, that’s your personal choice. And we get some very entertaining video out of it.

In the tactical world you’re going to be low with weight forward in something approximating a fighting stance when danger presents itself. In a competitive scenario... oh hey! You still ideally want to beclow with weight forward in something approximating a fighting stance in order to best control recoil, drive the gun hard, and leave that position without adjusting your stance to push off explosively. Bend your knees. Get your shoulders forward of your hips. If your thigh muscles aren’t burning a bit, you’re too tall. A good shooting stance is work. Legs working to maintain a semi squat, forearms and hands feeling the burn from gripping the gun so hard.
