Is there any difference between FMJ and FMC




i got this magtech 45acp 230gr FMC (45A)

tried looking for it on magtech's site but all that comes up is the full metal jacket, is the full metal case the same thing?

Some makers use the term FMC to denote that the round is fully encapsulated, i.e. no exposed lead at the base. Otherwise, yeah it's the same thing.

+1

FMC have a gas-check on the bottom, FMJ usually don't
No exposed lead means no leading in the barrel.

The other responders are right, in that some manufacturers' terminology indicates that the bottom of the FMJ bullet has a copper cover with no exposed lead. Hornady calls their's FMJ Encapsulated. Montana Gold calls their's CMJ = complete metal jacket. This design is especially desirable if you're shooting from a compensated pistol. Exposed lead base tends to melt off a little lead with each round fired. These vaporized lead particles can slowly build up in a compensator, and of course add lead to the atmosphere, a concern if you're shooting at an indoor range.

I have some 9mm Magtech bullets that are labeled FMC. They are the traditional FMJ design with an exposed lead base.
