    Crimp advice, please.

    Given that the photograph isn't perfectly focused, it's hard to be sure, but it looks to me as though the coating may have been cut - the ring around the bullet looks metallic to me. I agree that it would be interesting to pull a Syntech round to see what it looks like. I'd volunteer to do it except that I only ever had 200 rounds of the 115 grain stuff that I got from the prize table at a match about a year and a half ago, and it's long gone.

    Crimp advice, please.

    Which Federal load was that? For the purpose of this thread (coated bullets), I think the factory load most likely to be a relevant comparison would be Federal Syntech.

    Acme "new" 124gn 9mm: OAL?

    I'm guessing you mean 1.15, what with how 1.5 is 0.331 over SAAMI max length for 9mm?

    Glock 34 Double Diamond Barrel OAL issue?

    ^ This. My standard load for quite a while was a MG 124 JHP @ 1.075" - that was as long as they'd reliably plunk in my Walther P99 and P99c's barrels. 1.12 sounds almost luxuriously long to me. Of course, it's easy to understand the OP not wanting to disassemble thousands of rounds, so I guess either reaming or using the old barrel is probably the answer. Given that in an OOB detonation, the pressure gets "vented" wherever the barrel isn't supporting the brass, it probably receives considerably less mechanical stress in an OOB detonation than it does in normal firing. I'd be pretty surprised if it wasn't completely usable.

    Black friday components thread?

    Hoping that's correct. 125 TC 9mm case pricing works out to 5.74 cents/bullet, which is pretty amazing. I'm not currently low on bullets, but if I can get them at that price, I should probably order a solid mailman-hatred worth.

    9mm brass cost

    Chrono station simply has to be the best for that. :)

    Load for a Canik TP9SFx?

    I'd make an initial run of 10 or 20 rounds each at 3.6, 3.8, 4.0, and 4.2, test fire those over a chrono, and adjust as necessary from there. 9 different loads in .1 grain increments sounds like a really tedious time at the press to me, and you can probably get the info you need from .2 grain increments pretty easily. If 3.8 = 128 PF, and 4.0 = 136 PF, it's a good bet that 3.9 = 132 - it might not be right on, but at least using coarser increments will get you close, and it'll save you a lot of time fiddling with your powder measure settings and your scale.

    Load for a Canik TP9SFx?

    Oh, I knew about reamers - I just never really trusted myself not to ruin the barrel, and preferred to leave it stock anyway. I've since moved on to other bullets that are more short/tight chamber friendly, so I'm good either way.

    Load for a Canik TP9SFx?

    I have not loaded for a Canik, but if they copied the chamber/throat geometry from Walther the way they did most of the rest of the TP9 series from the P99/PPQ, then you'll likely have to load them to a fairly short OAL. I used to load 124 MG JHPs over 4.2 grains of N320 at 1.075" OAL for a P99c - any longer than 1.08" and they'd consistently fail the plunk test in that gun's barrel. The short OAL made CBC brass problematic with those bullets, just FYI. Primers looked ok, and it made ~130 PF IIRC. I ran the last few of those loads through my full-size P99 after I bought it, and they gained 40-50 FPS average from the half inch longer barrel vs the 'c.' Given that the Canik's barrel is longer still, I would guess that you could probably expect to make 130 PF with somewhere around 3.9 or 4.0 grains of N320. Usual rules apply, don't take my experience with a similar but not the same gun as gospel, plunk test your own gun, start low, work up carefully, yada yada yada.

    ES, New versus very used mixed brass?

    What group size were you hoping to see?

    Problem Headstamps?

    What bullets are you using? CBC case walls get thicker higher than most others, so if you have a bullet with a sharp shoulder at the base and/or you have to seat deeply, you'll run into trouble (usually bulging at the base of the bullet) more frequently. In my experience, Montana Gold bullets, especially seated deeply, are basically a no-go with CBC brass, but bullets with more rounded shoulders like Berry's Plated and Blue Bullets coated seem to work out better.

    CFE and FMJ/Coated

    4.3 sounds pretty light to me. It's not apples to apples, of course, but it took me 5.0 grains of CFE-P to get a 124 gr Montana Gold JHP @ 1.075" to 130 PF out of a Walther P99c (3.5" barrel). Obviously longer barrels and coated bullets will both result in higher velocities, but I'd want to chrono to be sure before relying on those loads to make minor with any cushion out of the pistols. (I'd be pretty surprised if a PCC with a 16" barrel wouldn't make minor plus some - you could probably even back off the charge and still have a healthy cushion there.)
  13. Hell, it's how I operate even with an auto-indexing press. Maybe less necessary there, but I still think it's safer.
  14. If you have to interrupt your loading rhythm for some reason other than a press malfunction, make sure you leave the press with the ram up/handle down - that way you can be absolutely sure of the status of every station. Any time you leave the shell plate full and the ram down and walk away, or even just turn your attention to something else briefly, you've got an opportunity to throw a double charge. If you leave the ram up/handle down, on the other hand, it's 100% obvious that your next move should be "lower ram" followed by "rotate shell plate." Beyond that, as others have said, visually verify every charge before you pull the handle.

    What PF do you aim to make?

    I'm pretty comfortable targeting 130 PF. That said, I usually have 12 FPS or lower SD, I don't travel far from home to shoot, and I'm not using a wide variety of guns. If I was expecting the same load to work in a bunch of guns, I'd figure out which gun has the "slowest" barrel, make sure that one makes 130+, and further make sure that load runs acceptably in the other guns.
