Universal Clays vs WST for 9mm minor

[njl]

I originally bought some WST for loading .45 as an alternative to regular Clays, looking for an easier way to make PF without exceeding max recommended load. Then I tried it out as a lower smoke alternative to Universal with BBI 130gr bullets.

I figured as long as I'm using WST for 9mm, I may as well try some loads with my usual load (124gr jacketed...either PD or MG). I loaded some samples of PD 124gr FMJ in the 4.3 to 4.6gr range. With each load, I got nearly identical velocity to the same charge weight of Universal.

This 8lb jug of Universal may be my last.

I tried 4.3 of Universal on some 124PDs and my slide would not operate

correctly (lock on the last shot),bumped it to 4.6 and it was allot better

but a bit snappy IMO...I had an OAL of 1.135...I am wondering if and OAL change would

hop up the smaller loads

Did you chronograph either of those loads? 4.6gr Universal put me up at just over 1100fps. 4.3gr Universal gets about 1060fps. I load the 124gr FMJs to about 1.145". I've been shooting the 4.3-4.4gr load for about 2 years, almost exclusively in Glocks, and it even ran a brand new Gen4 17 (before they had any of the revised recoil assemblies) without any problems.
