CZ85 Posted August 16, 2013 Share Posted August 16, 2013 Loading these for my CZ 85 combat for IDPA. OAL is great at 1.140. But where do I start my min load. Cant find any data except here I need at least the 125 PF for my new sport. Is starting at 3.9 grains to low. Im reading that people settle in at around the 4.3 grain range. It seems this powder has a small window between min and max loads. Oh I do have a chrono so what am I looking for as far as the fps goes with these berrys and also x-treme and RMR bullets Want to test all 3 bullets and finally pick the right one Link to comment Share on other sites More sharing options...

Sandbagger123 Posted August 16, 2013 Share Posted August 16, 2013 start at 4.7. even at that, you might not make pf. my load with a 124 fmj is 5.1 wst and it gets me 1085 fps Link to comment Share on other sites More sharing options...
CZ85 Posted August 16, 2013 Author Share Posted August 16, 2013 4.7 ??? I did find this so Im really confused. Are you sure your talking WST and not WSF ?? Loads from IDPA/USPSA guys 124gr - 1.140" - WST - 4.2gr. 4.7gr 124gr. WST - 4.3gr -1.140" PF 130 +/- Link to comment Share on other sites More sharing options...
Sandbagger123 Posted August 16, 2013 Share Posted August 16, 2013 (edited) 4.7 ??? I did find this so Im really confused. Are you sure your talking WST and not WSF ?? Loads from IDPA/USPSA guys 124gr - 1.140" - WST - 4.2gr. 4.7gr 124gr. WST - 4.3gr -1.140" PF 130 +/- The only way to be sure is a chrono, which i have. I can bet you dinner 4.3 will not make 130 pf. See if you can borrow a chrono or buy one. thye are about $100 and its easier to reload with one. I have gone through about 24# of WST the past couple of years.

kneelingatlas Posted August 16, 2013 Share Posted August 16, 2013 4.0 only got me 117 PF with plated bullets in a 4.5" CZ barrel so I would load ten rounds each: 4.4, 4.6, 4.8 and shoot them over a crono. I'm guessing all your bullets types will produce very similar velocities, so I wouldn't bother comparing them until you find your charge weight, then shoot them for groups side by side.

I have either Federal primers, Winchester WSP or CCI. Does it make a difference Link to comment Share on other sites More sharing options...
kneelingatlas Posted August 16, 2013 Share Posted August 16, 2013 As long as they're all small pistol primers, the brand doesn't have a significant effect on velocity; some say magnum pistol primers and small rifle primers bump the velocity by 30-40 fps, but they're harder too so if you have a light hammer spring I would stick to Federals if you can get them. I just use CCI or Winchester for minor loads. Link to comment Share on other sites More sharing options...

I just use CCI or Winchester for minor loads. My 85 came from CZ custom already with a sweet trigger job. I just got the gun a month ago. It was new from CZ custom last year. So I guess I will use my federals for this one Link to comment Share on other sites More sharing options...
G34Duck Posted March 10, 2015 Share Posted March 10, 2015 BB124 HBRN with 3.9 WST at 1.145 COAL avg was 1027 fps out of my G34 this weekend. 127PF at 50 degrees and extremely accurate. May need to step it up when the weather warms but what a soft sweet load Link to comment Share on other sites More sharing options...
