Showing the details of the shells used(where known)   Tweet Weapon Details Cannone da 75/27 modello 11 (Field Gun) History The Cannone da 75/27 modello 11 was a French-designed field gun, the first with a split trail, introduced in 1912 and produced in Italy prior to World War I. Used by Italian Alpine and cavalry troops during World War I, and was built there in large numbers. Manufactured 1912 - 1945 Calibre 75mm Length L/28 Rate of Fire 6 rpm   75mm AP (AP Armor Piercing) 75mm 6.35Kg 510M/Sec Range(Mtr) 100 200 400 800 1200 1600 2000 2400 Flight Time(Secs) 0.2 0.4 0.83 1.76 2.8 3.99 5.35 6.92 Penetration(mm@30°) 78 72 65 58 51 43 37 31 Penetration(mm@0°) 91 84 76 67 59 50 43 36 Hit Probability(%) 98 98 98 77 39 22 6 3 75mm HE 6.35Kg (HE High Explosive) 75mm 635Kg 510M/Sec ≈95.25Kg explosive Maximum Range 10000 Mtr Range(Mtr) 1000 2000 3000 4000 5000 6000 7000 8000 Flight Time(Secs) 2.26 5.35 9.8 16.81 29.41 58.82 205.89 Direct Fire Range(Mtr) 100 200 400 800 1200 1600 2000 2400 Flight Time(Secs) 0.2 0.4 0.83 1.76 2.8 3.99 5.35 6.92 Hit Probability(%) 98 98 98 77 39 22 6 3 Blast/Fragmentation Effects Burst radius Infantry in open 99% kill 3 mtr Burst radius Infantry in open 66% kill 7 mtr Burst radius Infantry in open 33% kill 19 mtr  Armour Penetration inc roof at 8 mtr 285 mm An explosion within 3 mtr of infantry in the open will cause 99% casualties - lethal. An explosion within 7 mtr of infantry in the open will cause > 66% casualties and could damage some AFV's. An explosion within 19 mtr of infantry in the open will cause 33% casualties. The blast effect of this shell exploding within 8 mtr of an armoured vehicle will penetrate 285 mm of the tank armour including the roof.

Hit probability is based on a static 2 x 2.4 metre panel at 0 degrees(vertical) at the range specified.

The data that has been used to create these records has come from Wikipedia, The Lone Sentry, The Bundes Archive and numerous books and websites that have provided the detailed information that has not been available anywhere else. The information we use to calculate the penetration tables, flight times and the hit probability comes from the Gun Calibre, the Shell Mass(Kg) and the muzzle velocity, plus range reductions to allow for gravity and wind resistance. This calculation originally came from a pre-war Krupp calculation which has been modified, and seems to fit the actual test results.
