I chronographed some 9 mm. loads today using Speer Gold Dots and some Hornady XTPs both in 124 grain weight. A Glock 19 was used for most of the shooting.
124 grain Speer Gold Dot
6.5 grs. Vihtavuori 3n37
CCI 500 primers
Winchester brass
1.130 inch overal length.
1185 ft/sec. average velocity
I started at 5 grains of 3n37 and worked up with five rounds of each to get a ball park velocity.
5.0 grs. 927 ft/sec.
5.5 grs. 1025 ft/sec.
6.0 grs. 1119 ft/sec.
6.5 grs. 1185 ft/sec.
The Hornady 124 gr. with 5.5 grs. Unique in Federal nickel cases gave 1149 ft/sec.
I tested two .44 Mag loads in a S&W 629-4 with 6.5 inch barrel.
250 gr. hard cast semi-flat point.
20 grs. old 2400
CCI 350 primers
Winchester brass
1371 ft/sec average velocity
300 gr. Hornady XTP
18 grs. H110
