I'm using PD 124 JHP V2's now in my Checkmate, I reamed my barrel and can load out to 1.168 but I'm using 1.160 OAL. Currently running 6.2 gr of CFE which is 155 PF for my local ppc match, but will load 6.7 for USPSA PF. Accuracy is great and dot tracks like I want it to. There was a sale on V1 a couple of weeks ago but I decided I'll stick with V2's.

I used 3.1 gr of N320 at 1.150 for my revolver and semi autos.

True if you ask 10 people you may get 10 different answers, they may all be correct, pick one that works best for you and don't worry about how other people do it. I have what works for me and sticking with it.

Hey Steve, I tested the V2's and will be sticking with them for the matches. No difference in accuracy with my guns and I'm loading them at 1.140". I did some post and updated my spreadsheet with the data. Thank you for making quality bullets at good prices. Highly recommend Precision Delta Bullets.

I shot a match yesterday with 124 V2's in my CZ TSO and My Ruger PCC. OAL was 1.140 and they functioned flawlessly. Took 1st with TSO and 3rd with PCC, this is only the second time I shot my PCC last match I shot it was two years ago. I bought 4K V2's and shot 1K so far in the past month. I've shot over 50K V1's and I'm sticking with V2's. At 25 yards the accuracy is the same, haven't tested to 50 yards since I don't shoot bullseye competition and not wasting primers right now.

I did a test with the V2’s the other day in my TSO at different OAL’s and 1.140 was most accurate. Tried 1.130, 1.125, 1.120, 1.110 and 1.100. Didn’t notice any difference in accuracy over the v1. Used my ransom rest to test at 25 yards. I benched it at 10 yards and they all went in one hole with the TSO and my M&P Core.

In all of my years of testing OAL makes a huge difference in accuracy depending on the bullet. For example PD 124JHP is loaded to 1.100 in PD's match ammo. In my reloads I started at 1.120 and worked my way down to 1.060 and found in my guns the best accuracy for me was achieved at 1.080 with that bullet. If you look at my spreadsheet there is all kinds of data you can look at concerning my testing of OAL. Now that I'm back home after the flood from IDA, I will be testing some of PD's 124 JHP V2's. I bought 4K and will start at 1.140 to start with on that bullet. Will let y'all know how it turns out. Haven't had access to my reloading equip. in 7 months. Looking forward to being back at the range testing again.

Does your seating die seat from the tip or the ogive? That makes a difference.

Sorry guys, I haven't been posting any load data revisions since I flooded in August. I'm back in my home now and my shop is coming together. Will be reloading soon with some Precision Delta 124 JHP's V2 and will post. I sure missed this place.

Bayou bullets were never powder coated the polymer coating was propietary and came from Austrailia. Anyone wanted to use the coating had to buy it from Donnie, including all the manufacturers using the coating today. Donnie sold the chemical. business to Alan Esterly and they have to. buy from him. So yes Bayou is the original polymer coated bullet.

I found .358" Bayou 160 gr was more accurate in my 929. I had issues with accuracy and was pissed until I went back in my logs from 30 years ago and found that on a revolver you go .001"over the cylinder diameter to get more accuracy no mater the barrel's bore diameter. ( This is old school revolver experts from the past) I found that they shoot great in my CZ's and STI DVC. You have to bell the mouth more as to not shave the coating off while seating and use minimum crimp. Very soft shooting and in my 929 out of my ransom rest I went from a best of 2.75" 10 shot group down to 1.09" at 25yds. Also my reason for going to a heavier bullet is the 929 has a twist rate of 1:10 instead of 1:16 which mean it will shoot a heavier bullet more accurately. ( I found that out when testing my Colt 1:12 twist to my S&W 1:18.75 twist with 125 and 158 gr bullets. the Colt shot the heavy bullet more accurate than the S&W and the S&W shot the lighter bullet more accurate than the Colt. )

Sport Pistol will be my TG replacement once I run out of TG. In my testing it has performs as good as TG and is cleaner. Vectan BA 9.5 is closer to N320 but there is no US distributor currently since Graf's gave up their distributorship. I received 36# of BR-5 from GIBrass recently and currently working up load for it. It is closer to Power Pistol than Unique in burn rate in my testing and has to be loaded to a higher power factor if you looking for accuracy. In my 124 gr JHP my normal 130-132 pf has to be loaded to 138-140 to be as accurate. Still leaves some yellow unburned powder residue though.

Bayou Bullets is local to me. They had issues with casting machines and not having reliable employee's. They are cranking out bullets as fast as they can. Most of the machines are up and running now, but they really need a couple of more to keep up with demand. Bayou's are a great bullet and is the original coated bullet and I noticed that some of the coated bullet offering from other manufacturers are not the quality you get from Bayou. DG bullets and Brazos Bullets are two of the top I recommend. The sudden surge since Covid has impacted orders from everyone, primers being the hardest component to get right now, and prices have more than doubled on primers.

3.8 gr N320 200 gr coated bullet at 1.190" gives 826 fps and a PF of 165.2 groups 1.89" at 25yds and is very soft.

I just bought 36# of BR-5 (Unique equivalent) from Gibrass to try. I already tested in 9mm and .45, will do .40 next.

I tested Precision Delta 124 JHP's today with the BR-5 powder I got in (36#) and was very impressed. Best group 10 shots ransom rest 25 yd in CZ TSO 1.09". 5.4 gr powder 1.100 OAL, CCI primer and Winchester cases. .378 crimp. Power factor 138 avg vel 1114 fps. I will upload a new revision of my spreadsheet next week after I test to other bullets 124 FMJ, 115 coated, 135 coated, and 147 FMJ and coated. Then work on .40 and .45.

I measure off the ogive, not the tip when comparing or checking OAL. Measuring all my PD bullets JHP, and FMJ's are within .002" off the ogive which is what will hit the rifling first.

Great group.

Updated yesterday, added Ed Brown M&P data. Brazos bullets also. Darrell's Load Data rev 050621.xlsx

The DR920 with the flat backstrap points good for me, for carry optic I can use my DR, P320 x5, or my Ed Brown M&P. The DR is more accurate than the other two. In carry optics during the match I don't think the accuracy difference matters that much it's more what trigger you prefer. I prefer my M&P trigger but can shoot the DR just as well.

I do almost the same. I have an OAL tester I made with Hornady OAL tool, I back off .015 and start from there. I look at max charge and subtract 10% and start there in .2 gr. My crimp is set at .378-.379. Once I chrono and accuracy test with my ransom rest, I take the most accurate one and start decreasing my OAL by .010, load 10 each at that powder charge and see if standard deviation and accuracy improves. ( i.e. Precision Delta loads their 124 JHP at 1.100, I found that that bullet is more accurate at 1.085 and that's what I use. Go look at my spreadsheet, I have OAL for different bullets in my guns and loads for the Shadow, Accu-shadow, and TS Orange.

I took cases for 9mm, .40, and .45 and drilled and tapped them to use the Hornady OAL tester. Works great the way I do it. I use my CZ barrels to test with because they have the shortest lead of all my guns, if my load is accurate in the CZ's they are accurate in the others. Once I find the OAL to rifling I back of .015 or so depending on bullet ogive and magazine and work up my charge in .2gr increments. Once I find the most accurate load I start working the OAL down in .010" increments to see if accuracy improves. That's how I came up with my accuracy loads. For matches I load to a 130-135 power factor.

The Zero 147 JHP at 1.100 (3.2 gr Tightgroup) will work great in your CZ's, the Acme will have to be plunk tested. My Bayou/Brazos 147 TC's are loaded to 1.130. I shot the Nationals with a CZ Shadow years ago when only three of us used CZ's. Now to be competitive in Production the CZ platform dominates. I have the Accu-Shadow for production and use a TS orange for local PPC matches. This year I'm dedicating myself to Carry Optics Division and shooting a P320 X5 Legion, or a Shadow Systems DR920. I currently shoot the DR920 better. Good luck to you. Check out my spreadsheet on this forum and it may give you some help picking a load.

Just heard today that Graf's won't be the US distributor for Vectan Powders anymore. Hoping someone else decides to be a distributor because I love BA 9 1/2. I was told if you want to be a distributor your are required to buy a minimum of 35K pounds,

I have both the DR920 and the MR920. Both guns reliable and accurate. Took about 200 rounds to break them in and during that time I had no failures. Have a Holosun 507C on the DR.
