Reloading guns (rifle, shotgun,) does not affect the shoot rate of the gun. So if you reload inbetween every shot and shoot, compared to just shooting it all out, you will have the same fire rate.
I just realized that reloading does not hinder your attack rate. So, with a gun with low rate of fire, you can actually reload in between shots and not waste (or hardly any time) compared to just spamming the gun.
gluttony: eat a lot
Sloth: sleep for no reason
Envy: beat the guy at the forest and use the binoculars to spy on rich mansion
Greed: work your way up and fire your friend for money
Lust: get maximum of a stat (depends on girl) and buy liquor for them then click on first option when you click on a girl
Wrath: click on the loser answers when you talk to the guy you made the 7 sins bet with
Pride: win the male contest at bar (get right answers and yes it does include the my hair answer and get max beauty stat)
