TxCoqui Posted August 20, 2019 Share Posted August 20, 2019 I bought 9mm 147gr precision bullets and I want to load them with CFE powder. Has anyone had any experience with this load configuration?I made a batch of samples with the following recipe:CFE powder 3.5 gr and 3.8 gr with the OAL set at 1.100”. Test:XDM 5.25 18 lb and 16 lb recoil spring bench tested. Both the 3.5 gr and 3.8 gr groupings were 1 1/2 “. This test results were great in accuracy, but I would like to hear if anyone has had any experience with this bullet configuration? Link to comment Share on other sites More sharing options...
GringoBandito Posted August 20, 2019 Share Posted August 20, 2019 I used to load copper coated 147's at 1.125 and 3.7/3.8 of CFE. It was accurate enough and the recoil impulse was very good. Link to comment Share on other sites More sharing options...
TxCoqui Posted August 21, 2019 Author Share Posted August 21, 2019 Does the OAL have a lot of effect on the bullet performance? I am basically running the same load but my OAL is 1.100. Link to comment Share on other sites More sharing options...
Demp223 Posted August 23, 2019 Share Posted August 23, 2019 XDm 5.25. 9mm. I’ve found .356 Xtreme and SNS 147s at around 920fps to be max accuracy. 4.0 CFE at 1.135-1.140 OAL. 16 Wolff recoil spring. Gun runs perfect. Link to comment Share on other sites More sharing options...

Other times the difference is pretty small. You won't know till you try it, but don't assume a certain length in another gun is best in your gun.

Even if gains were to be had, most can't shoot well enough to take advantage of them. Choose an OAL that functions and let 'er rip.

Yondering Posted August 23, 2019 Share Posted August 23, 2019 It's not a waste of time; I've found significant accuracy improvements with some loads. Others shoot well at any OAL that fits. You don't know till you try it. Link to comment Share on other sites More sharing options...
4n2t0 Posted August 24, 2019 Share Posted August 24, 2019 (edited) Define significant... Like I said, complete waste of time. Edited August 24, 2019 by 4n2t0 Link to comment Share on other sites More sharing options...
TxCoqui Posted August 25, 2019 Author Share Posted August 25, 2019 Great information. I will be going to the range today and test a new batch. I bought a chronometer to measure the bullet velocity. I haven’t changed the OAL since the previous test the accuracy was great and consistent. My my goal is to tune the load and change the recoil spring to get the XDM 5.25 to shoot as flat as possible.

TxCoqui Posted August 27, 2019 Author Share Posted August 27, 2019 I new to this. What would a faster power do? In what way will it help to shoot flatter? Link to comment Share on other sites More sharing options...

It will shoot flatter. Using a faster powder means that the build up of pressure in the case will be faster when fired...and therefore, the charge can be smaller. A smaller charge means less recoil. Look at all the minor load data here on the site. Most all are using a heavy bullet and a fast powder. Link to comment Share on other sites More sharing options...

Joe4d Posted August 27, 2019 Share Posted August 27, 2019 pretty much anything on the fast end of the burn rate chart. Tight group has heat and smoke issues with poly coated, but most of the others between it and 231 will probably be fine. Clean shot, AA2, VV320, Sport Pistol, American Select, 231, 244, Hp38, Link to comment Share on other sites More sharing options...
TxCoqui Posted August 27, 2019 Author Share Posted August 27, 2019 Great info. I will looking into other powders. On the other hand, I had pretty good results with the CFE powder with loads of 3.8 and 4.0gr of powder. Springfield 5.25 9mm 3.8gr Average Velocity: 994.5 FPS 4.0gr Average Velocity: 1025 FPS CZ Scorpion 3.8gr Average Velocity: 1086.8 FPS 4.0gr Average Velocity: 1115.2 FPS 1” groupings @ 25 yards Temperature: Texas *#&* heat 101DegF Link to comment Share on other sites More sharing options...
