TMJ vs FMJ Ammunition: What’s the Difference?

What is the Difference between TMJ (or TMC) and FMJ Bullets?

Total Metal Jacket or TMJ projectiles are fully covered by their copper jacket, whereas Full Metal Jacket or FMJ has expose lead at the base of the projectile.

Are TMJ bullets better than FMJ bullets?

There is not an accuracy difference between TMJ or FMJ projectiles and they can be found in the same grain weights as FMJ; 115, 124 and 147. So why choose a TMJ projectile over a full metal jacket? The fact the projectile is completely covered with no exposed lead, the Total Metal Jacket projectile will be cleaner, meaning you the shooter are exposed to less lead and your gun should be cleaner after a day on the range.
