I counted how many bullets Mista fired in Part 5 (desc.)
First of all, I want to mention that I counted the bullets while reading the manga. I don't know if the numbers are different in the anime, maybe I'll check it on my next rewatch.
- Attacking Sale inside the shack - 2 bullets (1st one hit a pot and the 2nd one hit Sale's right calf)
- Aiming at Sale on top of a truck - 1 bullet (it hit the enemy's forehead)
- Trying to hit Sale - 3 bullets (all of them got deflected by Kraft Work)
- Throwing Sale off the truck - 2 bullets (two bullets were fired in the same moment. The second one hit the enemy's neck, making him fall off the truck)
- Shot by an accident - 3 bullets (it happened after Mista got hit by Sale's bullet)
- Aiming at Sale's mouth - 1 bullet
(Summary of the fight with Sale: 12 bullets)
- Shooting Beach Boy's hook, which was climbing up his arm - 1 bullet
- Shot by an accident - 1 bullet (it happened because Beach Boy's line entangled through Mista's nerves)
- Shooting Beach Boy's hook, which was getting closer to his head - 1 bullet (Mista shot his left shoulder)
- Sending numbers 6 & 7 as scouts - 2 bullets
- Hitting Pesci's hand - 2 bullets (redirected by Sex Pistols)
- Prosciutto shot 3 bullets at Mista, but I don't count it since it's all about Guido's shots
(Summary of the fight with Prosciutto & Pesci: 7 bullets)
- The fight in his backstory - 4 bullets
- Aiming at the car's roof, hearing Ghiaccio's voice - 6 bullets
- Shooting Ghiaccio, while also creating heat necessary for Gold Experience's ability to work - 5 bullets
- Hitting Ghiaccio, right after he created an armor - 3 bullets
- Hitting Ghiaccio's ice skates - 3 bullets
- Trying to aim at Ghiaccio, panicking - 4 bullets
- The first attempt at finding Ghiaccio's breathing vent - 3 bullets
- Shooting the remains of his "snowboard" - 2 bullets
- Aiming at the car part stuck in Ghiaccio's forehead - 5 bullets
- Shooting the fish - 4 bullets
- Hitting the air vent - 1 bullet
- Shooting the vent once again, after Giorno splattered his blood on the frozen air - 6 bullets
- Pushing Ghiaccio onto the broken pole - 5 bullets (4 of them shot at his face and 1 at his foot)
- Pushing Ghiaccio even further - 11 bullets
(Summary of the fight with Ghiaccio: 58 bullets)
- Accidentally blowing up the kitchen in a restaurant, due to a gas leak - 1 bullet
- Shooting Carne's leg - 1 bullet
- Attacking Carne after realizing that he's a Stand user - 11 bullets

(Summary of the fight with Notorious B.I.G: 18 bullets)

- Bending a road sign - 3 bullets
- Trying to hit Secco, who's hiding underground - 3 bullets
- Attacking Secco, after he grabbed Mista's leg - 3 bullets
- Trying to shoot down the helicopter - 6 bullets
- Another attempt at shooting the helicopter, this time with Giorno's help - 4 bullets
- Sending Sex Pistols to kill Cioccolata after the helicopter is stuck - 5 bullets
- Number 5 fired a bullet to help Giorno, but I won't count it since it wasn't shot by Mista himself
(Summary of the fight with Cioccolata and Secco: 30 bullets)
- Now in Trish's body, testing out Sex Pistols' enhanced power - 1 bullet
- Making Chariot Requiem drop the arrow - 4 bullets (1 hit the arrow, the other 3 hit the Stand)
- Shooting Doppio, who's in Bucciarati's body - 2 bullets
- Shooting a criminal in the policeman's body, who tried to arrest him - 1 bullet
- Stopping Chariot from attacking Polnareff (Mista is now using a pistol instead of his revolver) - 6 bullets
- Shooting Chariot once again - 6 bullets (I think? It's really hard to count the shots when Mista is using a pistol, it's easier to count the shells tbh, but it should be correct)
- Trying to hit Diavolo who's running away, but it's not possible because of the time erasure - 6 bullets
- Shooting the Arrow, so that Diavolo couldn't pick it up - 13 bullets (9 + 4)
- Aiming at Diavolo; the attack is seen in King Crimson's erased time (Mista is back in his body btw) - 6 bullets (I'M NOT COUNTING IT because the action was reversed by GER)
(Summary of the final battle: 38 bullets)
- Shooting Rolling Stones inside of an elevator - 6 bullets
- Shooting Scolippi's hand - 1 bullet
- Wounding Scolippi's second hand, as a punishment for "lying" - 1 bullet

- Stopping Bucciarati from touching Rolling Stones - 6 bullets
(Summary of the fight with Scolippi: 17 bullets)
In total: 185 bullets
Why did I do this? I have no idea. I hope that everything's correct
