Is there any practical difference between TMJ and FMJ bullets? Ok, so I know that a TMJ (Total Metal Jacket) bullet is completely jacketed (including the base), while an FMJ (Full Metal Jacket) is coated everywhere but the base (The base is exposed lead). I've seen that this can lead to TMJ bullets producing less lead residue when fired.. Total metal jacket, or TMJ ammo, is very good for target shooting and was developed to reduce lead exposure at indoor ranges. It typically will leave less fowling in the barrel compared to FMJ ammo as TMJ bullets have an enclosed base.

While FMJ ammo features jacketed projectiles, TMJ, or total metal jacket, loadings take things a bit further. Notably, FMJ loadings cover projectiles in all areas except for the base of the bullet.. Why Was the Total Metal Jacket (TMJ) Bullet Developed? Although it is simple, practical, and economical, the FMJ can be argued to have one major design flaw: the base of its lead core, which isn't jacketed. Solid lead evaporates at a relatively low temperature for a metal (3,182 °F).
