I'd say these T&B bullets may hold some promise.

More to follow.

I'm ready to retest some 79gr T&B coated LRN bullets with N320. These bullets are a tiny bit heavier than optimal, so the slower powder may help. Some accuracy testing has already been done with these loads, but I wanted to go back and get chrono data on a range of loads just to be sure. This will be fun !


Equipment
Caliber:     32ACP
Bullets:     79gr T&B polymer coated LRN
Brass:       StarLine (new)
Primer:     Winchester Small Pistol WSP
Powder:    VV N320
OAL:         0.950"
Pistol:       Beretta Model 81
Qty:          10 rounds each, slow fired, target 30ft
Weather:   60F and sunny
Chrono:    ProChrono DLX
Max Velocity:  ~830 fps (calculated)


Load        Avg Vel           SD
1.7gr            726               n/a
1.8               803               n/a
1.9               834               n/a
2.0               877               19
2.1               909               10  (Best results)
2.2               948               14


N320 Notes
• Meters great
• Low smoke
• Great results from the start with groups slowly converging until 2.1gr
• Group at 2.2gr fell apart and was worse than 1.7gr

Finally got spare time, target delivery, and weather to all agree to let me go outside and play.

Data has been filled in above and here are some photos of targets placed at a measured 30ft, shooting from a supported position. The black bull is 2.3" in diameter for reference.


2.1gr N320 with the 79gr T&B polymer coated LRN


Of course, more testing is also needed with Vectan Ba10

My son (the crazy one) has gotten me into 32ACP. I know the CZ 83 is chambered in this caliber. Just wondering if anyone loads this already.

Oh, and I'm still undecided on a gun. I'd like to find a Pardini or Walther target gun, but they seem to go into safes and never see the light of day again.

I'll sell you my Beretta 81 that looks like it is unissued condition, with Farrar Indiana State police rubber grips -$500

Thanks Wobbly for renewing my interest in the 32 acp.  I still have several 32 pistols, but just have been shooting rifles more often than not for the last year plus.
