I believe Zig was interested in this and said i would post when i found it again.
I am sure somebody will probably have conflicting info tho
The material is from "Messerschmitt Bf109" by Heinz Nowarra. The test was at theroretical one by ballistics experts at Rheinmetall-Borsig assuming a range of 500m in a rear quarter attack against a stable 4 engine bomber NOT taking evasive action. It was estimated 48 rounds fired would give a 50% chance of the 4 hits required to shoot down the bomber. At 1000m it would require 120 rounds to get a 50% chance of a kill. A 95% chance of a kill at 500m required 88 rounds from 500m and 230 from 1000m.
Heinz Nowarra's comment was: "...But if the enemy aircraft reacted immediatly, its evasive action prevented it from being shot down. It was very rarely that even the most experienced fighter pilots achieved this theoretical kill rate."
Of course the Mk108 only had a 60 round belt. And of course the German fighter pilots solved the inaccuracy problem by coming in very close. Whether they would have the same chances versus fighter aircraft is another question.

I will leave it to somebody else to decide what that dispersion rate was but 48 rds at 500m only giving a 50% chance of getting 4 hits against a non evading bomber sounds like a sawn off shotgun effect.
