Hmm only two changes in the first packet.
Side facing hits can't hit the opposite side any more. It makes some sense but I'm not sure if it's any easier at the table.
Example: when shooting the side facing of a target, roll on the Front/Rear columns instead of the (deleted) side columns. If you are shooting at the right side facing of the target and you roll a LL, LA, or LT, Just move those hits to the right side instead.
Ammunition explosion damage capped at 20/20/10. I don't know if I have an opinion here.
