Chrono Data for 125 grn. Zero JHP with Clays

Recommended Posts

Temperature was 67 degrees and 48% humidity

Primers were Winchester small pistol magnum and bullet was Zero 125 JHP with regualr plain ol Hodgden Clays

Crimp was using Lee factory crimp die 1/2 turn after contact and EGW "U" sizing die

These were shot out of my Glock 34 with Bar Sto and factory barrel for comparison

First load was 3.6 grains of Clays loaded to 1.125"oal shot from Bar-Sto

Mixed brass Bar Sto-1028,1053,1021,1033,1024 for an average of 1031.8 PF=129

Starline Brass Bar Sto-1025,1028,1022,1021,1029 for an average of 1025 PF=128.1

Mixed brass from Factory Glock Barrel- 1055,1065,1070,1079,1057 for an average of 1065.2 PF=133.2

I'm assuming that the Glocks polygonal rifling attributes to higher velocity.

Loads felt soft and almost comparable to Atlanta Arms 147 Match. Slide tracked well but IMO could be a tad snappier like the AA load. But for someone looking for soft......this is soft.There was no visible smoke and no pressure signs.

i shot some today loaded with ranier 115 round nose and 3.7 grains of clays at 1.145"

1120 fps in the factory barrel Glock 34

1107 fps in the storm lake Glock 34 barrel

shoots about 3 inches at 25 yards with the storm lake tube, and a bit better in the glock barrel.
