3BM32/3BM42 performance proofs

Think I may have figured out 3BM32 Vant...  The info on Fofanov's sight may be outdated by a lot.  I used the length of 470mm from this, with the 30mm diameter.

 

The density took some trial and error.  But I came up with 17,200kg/m3.  Using the same velocity loss as 3BM42, so 1530m/s at 2000m.  One thing I've learned over time, is the Russians didn't use the highest density version of alloys.  For example their tungsten alloy is usually around 17,000kg/m3.  So it wouldn't surprise me at all of their DU alloy was also close to that.

Decided to see if I could get Svinets to work.  I used the same alloy density as 3bm32.  Going by dimensions and initial muzzle velocity from this.  Then used the 300mm figure to come up with a velocity table.

Vertical

    10m = 567mm  1650m/s

  100m = 565mm  1641m/s

  500m = 555mm  1605m/s

1000m = 542mm  1560m/s

1500m = 529mm  1515m/s

2000m = 514mm  1470m/s

 

60 Degree

    10m = 331mm

  100m = 330mm

  500m = 324mm

1000m = 317mm

1500m = 309mm

2000m = 300mm
