Hey everyone. This is my first post to the handloading section and I just thought that I would share some load data that I have gotten for the .32NAA cartridge. Please note that the 'gun' used to fire these rounds was actually a locked-breach test barrel with 2.75" overall length, so YMMV some...

COL = 0.970"

Hornady 60 grain XTP bullet with N310 powder

2.8 grain : WSPP = 1093 ft/sec, CCISPP = NA
2.9 grain : WSPP = 1042 ft/sec, CCISPP = 1079 ft/sec
3.0 grain : WSPP = 1116 ft/sec, CCISPP = 1115 ft/sec
3.1 grain : WSPP = 1126 ft/sec, CCISPP = NA
3.2 grain : WSPP = 1197 ft/sec, CCISPP = NA

No overpressure signs were observed

Speer 60 grain Gold Dot JHP with N310 powder

2.8 grain : CCISPP = 1068 ft/sec
2.9 grain : CCISPP = 1094 ft/sec
3.0 grain : CCISPP = 1142 ft/sec

Testing was halted due to lack of ammunition. No overpressure signs observed.

Test those Gold Dots for expansion/penetration/weight retention yet?

FWIW,

The trim-to length of the .32NAA is the same as for the .380ACP - 0.677". I can't find this information in any reloading manual, but I used a collet-type puller to disassemble some cor-bon factory ammo - all cases measured either 0.676" or 0.677".
