https://frangiblebullets.com/frangible-projectiles-not-loaded-ammunition/9-mm Super high quality guy to deal with.

Load 100gr. Berry's in front of 2.5 N310 and tell me if it doesn't feel like butter. Recently I have experimented with 65gr frangible ( big bullet due to not lead ) and they shoot quite nice with 2.5gr n310. I have zero issues with OAL of any bullet. I run the taccom upper feed ramp and a stern defense mag adapter ( due to CT pre-ban ).

It is part of the retainer assembly. Here is explanation: https://www.jprifles.com/buy.php?item=JPSCS-BRP

From what I saw there was a bit of a dry spell on matches posted, there were a few days w/o any NEW results. It did clear up and a bunch showed up to your point, but still no US STEEL NATIONALS. From a few days ago;

“Anyone…? Anyone…? Bueller…? Bueller…?” Where's the official SCSA results from the 2024 US Steel Nationals Match back on 3/15 - 3/17 ? If you have insight, I'd luv to hear it. I see the match results on PS https://practiscore.com/results/html/f77344ca-f57d-4a7d-90b5-647bdfc51e28 however the official SC results page https://scsa.org/results list no results. This is a Level 3 match and the second most important match in the hobby next to the worlds. I also can see that several outstanding times were laid down across several divisions. It will certainly shake up the rankings for 2024 and TopShot2024. http://www.steelrankings.com/ I suspect some back office administration arm wrestling over fees, or maybe I/T SNAFU. I know the range venue is top notch, so can't imagine what the delay is about. Congratulations to the competitors who put in the hard preparation work and "got it done" during match time. I wasn't able to attend, but living vicariously through your results. OK, I'm mostly better, rant over....

Yes, I use them all the time. 4.0 of N310 is the same as the Atlanta arms 100gr ( also Berry's ) steel challenge load. ~ 109pf. I typically load them at 2.4 of N310 for PCC.

A few shakeups in the 2024 Season of TopShot2024. Some unexpected member expirations and several big matches caused a fair amount of movement in rankings. Keep an eye on your USPSA membership expiration, else you risk dropping from SCSA ( Top 20 ) and SteelRankings. http://steelrankings.com/ Follow your SCSA link to see your expiration;

Yes, mostly; It appears the lock ring groove in the weight carrier is a bit oversized and the groove has some play. Whether this is root cause or not who knows; I have (2) setup different weights ( custom made aluminum on the one ); The slot is MUCH tighter on my spare ( AL ) than the mixed steel / tungsten; So... I am not sure how to resolve as they don't sell the 4 weight carrier any more ( current = 5 weights ). I am thinking maybe to try double up on lock rings ? Ideas and comments welcome. For now, I'll swap over things to the other weight carrier with a new lock ring;

As I have been going through alot of o-rings, I found these listed as a suitable replacement on some AR forum. I have them coming today; will report; back; https://www.amazon.com/dp/B0051XXWEC?psc=1&ref=ppx_yo2ov_dt_b_product_details I'd like to find an amazon replacement for the lock ring to expedite things;

I spoke to JP, they didn't have any 'aha' moments, but also suggested maybe the lock ring was damaged. I'm very careful in installing the o-rings via rolling over the weights. They said the order of the weights on the carrier is not relevant and would not have any effect. I'm leaning towards either the lock ring or carrier groove is the culprit.

So I need to resurrect this thread after this weekend. I run very low power factor 9mm ( like 82-85pf ) ( 100grain ) Prior to steel challenge match ( 230 rounds ) I inspected my SCS and found that the o-rings were ALL torn ( and they were pretty new ) and the lock ring was pushed out and the weights were moving freely on the SCS shaft. No a good thing at all; No idea how I finished prior match in that condition. So, I rebuilt with all new o-rings ( my config has 4 weights ) ( 2 steel / 2 tungsten ) and off I went to match. next day all clean and reassembled. I use a rifle length tube with a JP plastic spacer and 1 quarter to properly space the SCS. After the 8th stage, I inspected and the SCS was again trashed. ( 230 rounds only ) I had to pull with force to get it out of buffer tube ( normally it is smooth as silk ). O-rings trashed, lock ring popped up; visible wear on the piece that is adjacent to lock ring. Not sure where to start, or what it could be. I alternate steel / tungsten / steel / tungsten and another competitor said I should locate the tungsten closest to the front of the gun, but the JP assembly video showed them mixed, so not sure if that holds any merit. Should point out gun was running reliably the whole time. Something is clearly wrong; Ideas ?

Weekly Ranking updates done; Volume of matches & shooters is picking up in 2024; I know my ranking has decreased a few notches as more and more shooters get out there. I need to play less pickleball and do more shooting !!!! http://www.steelrankings.com/

DNF = Did not Fire DNF is for an entire stage; it essentially equals getting a 30 on every string, but without firing. If you took a shot and then gun breaks you get 30s and not a DNF. You can DNF on any stages; - scenario 1 ; yes ; and then can resume shooting on stage 2; - scenario 2 ; yes ; if you gun were to break or become unreliable on stage 2; you would just DNF for each remaining stage in that division as an example; I've done this with RFPO myself when stuff just not working right; Not worth the aggravation to keep shooting it;

Weird: I tried on my phone / laptop / wife, etc; and all show 1/31; Perhaps hit refresh on the page; I know sometimes my browser caches and even though I 'dirty' the cache it doesn't always recognize; Please confirm it works or NOT !
