locochinoloco Posted May 20, 2014 Share Posted May 20, 2014 I guess my thinking is USPSA/IDPA based. I use WST for practice ammo only. WST is too inverse temperature sensitive for me to use it as match ammo. With that said, you'll load a little more WST in the summer and a little less in the winter. My objective is stay above 125 PF on my practice ammo, but no so much as to waste powder. My match ammo in 9mm uses VV N320 and WST "feels" the same to me and it's generally half the price. I've notice the CZ's I have love shorter OAL's but I would only drop the OAL if it were to achieve better accuracy. I would NEVER use a reduce OAL to get a few more FPS out of a load... it's just not a safe way develop a load due to the increased pressures involved. Every gun and every barrel are different. The first step is find a safe load that will yield a suitable power factor. The next step is to find which load among your safe loads is more accurate but still manageable. I say manageable as sometimes the more accurate loads are much higher power factors but the higher power factor often means more muzzle flip and therefore more time between shots. It used to be fun developing loads, but now it seems too much like work. Enjoy it while you can. Greatly appreciate the tips. I've just started to reload and it's already started to be annoying due to the scarcity of powder and primer. Link to comment Share on other sites More sharing options...

Butterpuc Posted June 2, 2014 Share Posted June 2, 2014 Looking at some of the previous data from some of the posts (spreadsheet some where in here)... It looks like there is not much difference when loading 3.4 - 3.6gr of WST with a 147gr bullet. I wonder if this is why Winchester is concerned with using WST in a 9mm case?

jayjay1 Posted August 16, 2014 Share Posted August 16, 2014 Back in, hi to everybody: Well, the 147gr. load with WST became my favorite to make Minor PF. Now I want to try a 158gr. bullet with WST and want to ask for some load datas, has anyone tried this yet? Especially powder charge and OAL would be a blast. Cheers, Jay Link to comment Share on other sites More sharing options...
NPSS Posted November 3, 2014 Share Posted November 3, 2014 Just a update for more data points. I shot NC and SC this year. Not sure the temp difference but both times I chromed the 2/3rd stage of the day. 3.7 WST with a Blue bullet 147gr round nose @ 1.110. was 142PF. 3.5 WST with a Blue bullet 147gr round nose @ 1.110 was 131 PF. Gun is g4G17 stock barrel. Link to comment Share on other sites More sharing options...
inertia Posted November 3, 2014 Share Posted November 3, 2014 (edited) Here is some data I got in CZ with Australian barrel. 1.110-1.115 135g bbi coated 4.1 1039 average 140.27 PF some pressure signs 3.8 982 average 132.6 PF 3.5 968 average 130.68 PF I am going to go a little lower see how linear things are. ES and SD were much better with the lower charge than the higher. Edited November 4, 2014 by inertia Link to comment Share on other sites More sharing options...
IronicTwitch Posted November 11, 2014 Share Posted November 11, 2014 Finally bought my own chrono so I could confirm my new load before winter sets in and reloading season starts! 4.0gr WST 124gr FP Extreme 1.07" OAL (nice and short for my CZ's, 1.08" plunks but didn't spin in my P-01) Chrono results using my P-01 with a 3.65 inch barrel (per CZ UB measurement of 92.5mm, CZ USA measures it at 3.8 inches): Low 995 fps High 1030 fps Avg 1015 fps PF = 125.86 BARELY made minimum BUT I usually shoot a TS with 1.5" longer barrel so I should be closer to 130PF with that gun. Need to do some experimenting with the crimp or increase to 4.1gr WST to see if I can group as tight as I was at 1.08" OAL I loaded last winter.

rdinga Posted November 12, 2014 Share Posted November 12, 2014 4.5 WST Bayou 124 TCG 1.13 OAL Very accurate in Glock 17 and 17L have not had time to the chrono the load yet. Link to comment Share on other sites More sharing options...
inertia Posted November 12, 2014 Share Posted November 12, 2014 I finished this off again CZ shadow with AUZ barrel bbi 135 1.110 oal WST 3.4 953 ave. 128.7PF 3.3 940 ave. 126.9PF So bottom line is with coated bullet in a full length barrel very little is needed to make pf. I see loads at 4.5+ and that seems scary to me anything over 4 was showing me some primer flow in my gun. Link to comment Share on other sites More sharing options...
Nickb45 Posted November 12, 2014 Share Posted November 12, 2014 A lot of data in this thread. I'm pretty well stocked up on WST for 45s. Good to know I can use it if I run out of Titegroup in the 9mm. Link to comment Share on other sites More sharing options...
connermorrow Posted November 16, 2014 Share Posted November 16, 2014 125gr. Moly coated bullets with 4.7gr. And 1.160 OAL. Have not cronoed it yet but feels ok. Will be loading up some 147gr. and doing more testing with that soon. Good to have a starting point for that. Link to comment Share on other sites More sharing options...
MemphisMechanic Posted April 13, 2016 Share Posted April 13, 2016 (edited) Here is all of my chronograph data for WST in 9mm, shot across a ProChrono at an indoor range. Bullet weights range from 124FMJ to a 130 and 135 Black Bullets International coated bullet. Pay attention to which gun was used - you'll see a Glock 34, 5" M&P, and a 4.25" standard-length fullsize M&P in the results. Charge weights are noted to the hundreths because I drop ten charges on the scale and take an average. Barrel: 5" M&P 9L / Apex SDI fitted barrel Temperature: 65 degrees F (indoors) Bullet: 130 gr BBI Powder: 4.10 gr WST Brass: Mixed headstamps OAL: 1.110" Primer: Winchester 1027,1033,1032,1053,1048,1020,1013,1063,1036,1041 Average = 1036.6 fps PF = 134.75 ES = 36 fps SD = 15.18 (Same load as above. Glock 34 factory barrel, back to back:) 1006,1014,1051,1043,977,1054,1054,1036,1034 Average = 1029.88 fps PF = 133.88 ES = 48 fps SD = 26.11 Barrel: 5" M&P 9L / Apex SDI fitted barrel Temperature: 65 degrees F (indoors) Bullet: 135 gr BBI Powder: 3.60 gr WST Brass: Mixed headstamps OAL: 1.130" Primer: Winchester 928,932,913,921,948,937,935,929,919,949 Average = 931.1 fps PF = 125.7 ES = 36 fps SD = 11.77 Barrel: 5" M&P 9L / Apex SDI fitted barrel Temperature: 65 degrees F (indoors) Bullet: 135 gr BBI Powder: 3.80 gr WST Brass: Mixed headstamps OAL: 1.130" Primer: Winchester 983,974,994,957,1000,993,998,989,966,988,975,976 Average = 982.75 fps PF = 132.67 ES = 26 fps SD = 13.33 Edited April 13, 2016 by MemphisMechanic Link to comment Share on other sites More sharing options...

Dropped charge by 0.1 grain and still saw an increase in velocity. Barrel: 4.25” M&P factory barrel Temperature: 65 degrees F Brass: Mixed headstamp Bullet: 130 gr BBI Powder: 4.0 gr WST OAL variation: 1.050-1.055" Primer: Federal 1035,1066,1046,1029,1024,1032,1031,1020,1070,1062 Average = 1041.5 fps PF = 135.4 SD = 17.37 Changed guns and re-tested the above load Barrel: 5” M&P Apex Semi-Drop In 1063,1095,1056,1101,1072,1059,1050,1084,1090,1037 Average = 1070.7 fps PF = 139.1 SD = 20.09 Starting load with a 124 fmj for indoor matches and situations where I might shoot an outdoor stage with the sun in my eyes in the morning. Very little smoke. Barrel: 4.25” M&P factory barrel Temperature: 65 degrees F Brass: Mixed headstamp Bullet: 124gr Precision Delta FMJ Powder: 4.0 gr WST OAL variation: 1.1.135 – 1.140” Primer: Winchester 1049,1062,1085,1006,1073,1039,1048,981,988,1025 Average = 1035.6 fps PF = 128.4 SD = 33.34 Changed guns and re-tested the above load Barrel: 5” M&P Apex Semi-Drop In 1038,1081,1101,1059,1073,1112,1072,1088,1103,1145 Average = 1088.46 fps PF = 134.9 SD = 27.39 Testing my new load with a 135 BBI for this weekend’s sanctioned match. Very soft for 133 PF and only slightly smoky. Leaves the gun’s action cleaner than Solo1000 did. Also very accurate. 4-5" offhand group at 25yds which was not shot slow-fire and unsupported - how you'd shoot a distant target in a match. I expect group size to be around 2" with the gun bagged in, perhaps less. Comparing the speed of the APEX semi-drop in to the factory barrel.
