This exact scenario happened to me this year in limited. Still unclassified after first 3 classifiers, then add in 6 more for special classifier match. Those last 6 were sorted with highest being most recent. Initial classification was the 4 highest from special classifier. In this example: 90, 80, 70, and 60 = 75% (A class). Then the next week it recalculates top 6 of 8 (add in 75 and 50) for initial classification % of 70.83%, but still A class. The 40 and 50 are the lowest 2 of 8, so not counted, and the June score of 25 is never used. From that point forward scores below 70% are flagged for below A class, and you go up from there.
Makes sense to me I think.
Maybe it can can be summarized that you get one “process” a week, and that your process works oldest to newest as you would expect but you won’t “skip” initial classification rules even though you have more than the 6 required.

For CMMG Radial Delay Blowback... I'd recommend ejector springs swapped out at 5k rounds or... for me... I'm just keeping a MATCH-ONLY bolt around and going to refurb it every season. Moving the old MATCH-ONLY parts over to my training bolt.
I went 10k in a couple months without anything breaking, but had a jam (FTE, weak ejector spring) on a classifier I was about to 100%. So... time for a match-only bolt.

This should be easy, but I don't really get it.
Shooter has 3 matches under their belt. Classifiers with scores of
AUGUST 25%
JULY 50%
JUNE 75%
If shooter shoots a 6 stage special classifier at
90
80
70
60
50
40
According to the rules, the first four of six will be accounted for, but also special classifier matches are ranked high to low. What is the shooter's percentage?
Does the 75% from June count at all? Does the classifiers of 60 50 40 get combined with the previous three scores and drop the lowest two (75+50+50+60 = 58.75)? BUT THEN... you'll have 8 scores existing, meaning it would be immediately reclassified/scored to (90+80+70+60+50+50 = 66.6)?
I guess I'm wondering because depending on the numbers for something before a special classifier match it could help or hurt you.

I don’t run 50+ mags in uspsa matches and the specialty matches I have shot, there is always a spot to reload. Making people reload just to reload does nothing for a platform where wether you run Glock, colt or mpx, you have options to carry up to 40rds in a stage with simple addition of a basepad. On a large field course with 32 rounds, I only load my mag up to 38 rounds most of the time anymore. If I have to do s reload on a stage I’ve lost or had a gun malfunction.
This sounds like it fully avoids the word "practical" in USPSA.
I checked your scores on classifiers that have reloads, this obviously wouldn't be a problem for you to throw a reload in per stage. It's just keeping the spirit of the game. If PCC only competes against PCC, what is the problem with tossing in a 30 round cap? It would eliminate the silly socks walking arond with 60 round extensions because they straight up lack the ability to reload. It would make stage planning mean more for PCC, that's a huge portion of the game imo.

LOL, I wouldn't take a bunch of people switching around as an indication either way.
The truth is the new divisions (CO and PCC) will be popular with people who think "maybe I'll be better at that!" then realize they both take work and switch back to Limited or Open. I've seen enough unskilled shooters pick up PCCs thinking it'll be easy to know the real problem is people just don't want to put in the work in any division.

I think this may work out ok
Either way, I needed a few new flags.
Looks ideal.
I have full length rail, but did consider adding an MLOK section of rail, then the issue is its still a little loose.
Someone could make this product a lot better by using a plastic with a softer durometer that clipped on vs slide on.
But yea, you have a good setup there for it.

Reloading with a pcc is not that same as reloading with a rifle mag.
That's EXACTLY what it is for me
https://www.cmmginc.com/9-arc/
I'm glad more than just me think 30round mag limit would improve PCC division. I get it, it's currently "open", but the point is PRACTICAL and 50-60 round glock mags are not that. I don't think there are enough shooters for PCC Limited and PCC Open, but really it's just entirely past the point to have 30-33 round medium stages where you don't have to reload at all.

My 8" 9mm doesn't have enough gas to engage a brake. Good luck on a 16" gun!

Hold my beer . . . slides on the rail.https://www.amazon.com/Monstrum-Tactical-Chamber-Flathead-Picatinny/dp/B07D6SYQJZ
This is what I use.
However... They don't seem to CLIP on to the rail and stay put. The plastic is too stiff for that. Instead, they slide on, and for me, the only place it wouldn't slide off is if I put it all the way down on my top rail which gets my hand quite close to the muzzle putting it on, I don't want a bonehead DQ... So I still just pocket this.
-
I can probably be ignored because I'm using PMAG conversions instead of Glock mags.
But when I see people mess up reloads with PCC, it has nothing to do with grabbing the mag.
As an aside, it's a good thing I'm not in charge of USPSA, because I'd put a mag limit on PCC to 30 just to force people to have to actually be competent in running a carbine.

PCC is all about speed and accuracy. No time to brace wall or port to shoot targets.
I don't know how it took so many people so much bickering what is clearly stated in the rules as legal - BUT -
This has nothing to do with barricades.
I have an 8" barrel PCC, I'm 6' tall.
I have a vertical grip extended as far as I can comfortably get to the muzzle because if I don't, I'm choking up on the rail. I use it as a handstop more than anything else but where the BCM KAG and other such grips work well, I like bit more vertical to get my entire hand on (not around).

Pros and Cons - MPX is way softer, but dot settle time is slower and its inherently LESS reliable than a blowback AR. AR, even with the softest load and buffer aftermarket junk, will never feel like an MPX - with the right load the dot will recycle faster.
You should try the CMMG.

What receiver did you use since it needs the biggest port
Sorry I'm just getting to this now.
The 9mm does not need a different sized port. 40 and 45 do, but 9mm is about the same size as 556 just shorter.
HOWEVER... I chose the Aero XL upper because it's a larger port made for 458 because I wanted to make sure if there was a malfunction I could get more of my hand or tool in there. So, while it does not need it, I think the Aero XL upper is excellent. I'd strongly consider putting one of these on my next 556 built. For reference, the dust cover is the same size, but it's just a slightly larger milled hole.

Totally new carrier design to eliminate tilt (thus less energy req'd to cycle) gas port sizing, etc.
Gen 1 pistol or Gen 3/PCC at this point.
So did they massively reduce the peak bolt velocity or overall cyclic rate down from 1100 actual (850 claimed)?
OR did they just increase the size of the operating window? -

I have both. Get the new version. Definitely. Sig appears to have really addressed the reliability issues through a multitude of changes in this model.

Wow that's a lot. I did not record temperature, but I did measure velocity in December and July, outdoors, and the difference was nowhere near that much. You're sure it's not the chrono?
Well... That's the rub isn't it!? I tested three chronos over 80-95 degrees, always approx 1040-1050. Then at 60 degrees and it goes sub-minor with range dual chrono setup. So... while I could maybe say their chrono was slightly off, something else had to be going on. RM went on and on about her "certified ammo" (eyeroll).
21 minutes ago, GMP said:The dirtiness alone tells me something is wrong here. I process my own brass as well as pickup stuff and for sure mine is cleaner than average, from four different guns. I've seen plenty of blackened cases but none were mine, usually from Titegroup. If you need to load longer for feeding up the charge, if not nothing wrong with a bit more bullet in the case for a 124g.
I feel ya. But I'm not about to load more/hotter to get it cleaner. I'm between min and max. I'll retest moving from 29mm to 28mm. But unless they miraculously come out clean, I'm just done with this stuff.
I would be willing to accept a slightly unexepected temp sensitivity, or dirty rounds - but not both.

I've been using this since its introduction with no problems and excellent results. My OALs are much shorter (CZs) with Brazos and Precision coated 124g, so less case space with 3.8 to 4.0g. With RMR jacketed 124g I run 4.2g. Federal primers. I've never seen seen dirty cases which usually mean poor seal from low pressure. Try upping the charge a bit.
I'm out of the test pound, not going to open another.
HOWEVER... I have a little left. Instead of loading at 29mm, I'll load at 27 and 28mm to see if the filthiness changes a bit. But, betweem the losing 40-50fps at 30º delta and the dirt, I'm not expecting magic. I'll remain open minded, but I don't want to load much shorter than 28mm (1.10").

Handloads with mis-matched primers, wonders why chrono stats are garbage...
Yea. You're probably right! Despite testing multiple times with S&B, Win, Federal primers all separately (no major differences in speeds).
Like I said, I'm sure it works great for you.
In the event future-me see this thread, maybe they'll know not to waste their time on this. But again, it probably works excellent in your gun.

This powder sucks. It is in no way a replacement to N320.
I chronoed 130-131pf at 90 degrees with 124 and 6" barrel. Same gun at 60 degrees chronoed exactly 125pf. Don't trust it. If it was 59 degrees and it was a match with a chrono I wouldn't have made it. 50fps over 30 degrees isn't acceptable.
For all the accounts of how clean this powder is, I'm using 3.9gr and the cases are all have a black band running down them, absolutely filthy compared to any factory ammo, the target holes are surrounded with a gray ring around every shot.
Maybe it's just the gun, maybe it's me, maybe it's the 1.14 OAL, maybe it's the three different types of primers, maybe while it sucks in every respect for me it'll work for you... I'm sure it'll work better for you, but I think this powder is absolute garbage.
If I needed something in a pinch locally, I'd probably reach for CFE Pistol next, but I'll stick with N320 as long as possible.

I'm going to recommend the CMMG bolt and barrel. You aren't going to go for it because reasons... But I did my part.
Once you know, you know.... Almost no one knows yet.

Two questions...
1. Anyone have PCC video of this? I'll figure out if it's better for me to reload before moving on string2 or after running back, but a video might save me some testing.
2. How much distance can you move forward from string1 start while still seeing the left and right targets? @waktasz video appears to be only a couple feet, so I'm not sure it's worth moving before shooting both of those.
ANSWERED MY OWN QUESTION:
-
On the topic... I had though the NO BRACES rule was dumb, but after seeing enough braced guns with questionable shooters behing them, I kinda get it.
But what is the official reason to not allow braces?

I've been helping with (2) level 2 USPSA major match's at our club in the last 4 weeks. I've been buried. Sorry for the late response. I would rate reliability equal on all 3.
My only other failure was a extractor roll pin in my CMMG fell out during a match. I had removed it from the bolt for cleaning the extractor. It went in back in all to easy. Should have been paying closer attention. More of a self induced problem than a design problem. I love shooting all three. I would recommend all.
You think it was a bad roll pin? What would you have done differently noticing it went back in too easily?
Classifier match when unclassified
in USPSA/IPSC Rules
Posted · Edited by Bifurcate
Just a slight note to that. You can have B flags while being unclassified!
I zeroed my second classifier, and got a B because the score was less than 2%.
