What exactly changed with organ guns?

I saw the patch update, but the spread dmg is confusing, as secondary bullets seems to do 1 dmg still(i tested).

Also, did they always do more than 20 dmg on their primary bullet? I never really used them in the editor before, can someone confirm that they could, say, 2 hit kill arbalests pre-patch, meaning roughly 26 dmg on primary bullet? Maybe it always was like that, so this could be nothing.

Also, watched a stream with viper+tatooh the other day, they seem to think it was noticably stronger than before, when playing DM.¨

Not exactly sure whats going on with this unit, then again, its not a unit i have had much interest in after the min range was introduced, so i cant really remember.
