-Increased Spread Decay to 15 from 10.
-Increased Spread Per Shot to 8 from 6 (cosmetic).
-Increased spread slightly (Pellet Scatter Pitch to 2.3 from 2.1, Yaw to 3.833 from 3.5).

-Increased number of pellets back to the vanilla value of 8.
-Reduced damage per pellet from 67 to 60.
-Reduced PenetrationPower from 75 to 67.
-Very slightly adjusted spread, barely worth mentioning.

-Widened spread slightly. It really was too narrow before.
-Reduced damage from 72 to 67. Was resulting in higher DPS than my rebalanced Pump Shotgun, now it only has a rough DPS of 469 compared to the Pump's 450. It's already deadlier due to tighter spread, even after the aforementioned slighht accuracy reduction.
-PenetrationPower increased from 50% to 75%, allowing for higher damage to subsequent targets behind primary target per pierce. Overall, the Chrome Shotgun will drive narrower, deeper holes into crowds compared to the wider-reach shotguns, at the cost of overall horde practicality.

UPDATE:
Decreased accuracy slightly. Minor penetration value tweaks. Improved description.

Significantly reduced total damage per shot from the overpowered 776 to a much more balanced 504. It's still really powerful, but won't near-break Special and Boss balance anymore.

Slightly reduced accuracy again.

Slightly increased spread. Slightly improved description.

Nerfed the damage again (and piercing damage percentage), since it was proving to be too strong for balance. It still sits higher than it was before my major buff update with more testing to follow.

Major update to damage, piercing, piercing potential, and changed ammo type back to Autoshotgun ammo, so that people who don't use my gamemode script can still at least get 90 reserve ammo.
