Here is the most complete set of 'load data' that I have to date with my tinkering with the .32NAA cartridge.
A few notes : all primers used were CCI Small Pistol Primers, the first screen on the chronograph was placed 6 feet in front of the muzzle and the 'gun' was actually a .32 caliber blank that I chambered for .32NAA and turned down on a lathe to the external dimensions of a 3" magnum 12 gauge shotgun shell. This 2.75" barrel was then fired in a single shot shotgun with 24" barrel length.
Powder Charge (gr) Bullet type Velocity (ft/sec)
----------------------------------------------
Bullseye 2.4 85gr XTP no
Bullseye 2.6 85gr XTP 840
AA#2 3.0 85gr XTP 931 (cracked case neck)
N310 2.2 85gr XTP 787
N310 2.3 85gr XTP 844
N310 2.4 85gr XTP 847
N310 2.5 85gr XTP 925
N310 2.6 85gr XTP 896
N310 2.3 60gr XTP 741
N310 2.4 60gr XTP 774
N310 2.5 60gr XTP 818
N310 2.6 60gr XTP 910
N310 2.7 60gr XTP 882
N310 2.8 60gr XTP 915
N310 2.9 60gr XTP 928
N310 3.0 60gr XTP 1057
N310 3.1 60gr XTP 1045
N310 3.2 60gr XTP 1075
N310 3.3 60gr XTP 1106
N310 3.4 60gr XTP 1180
Testing halted, no overpressure noted on either XTP weight
I hope this information is useful to you. I like reloading the .32NAA because, well I guess no one else does it. It's a neat little cartridge, like the .357SIG, but for a mousegun.
