What is the difference between 9mm FMJ and 9MM MC? I searched online and cannot seem to find anything?

MC has a fully coated bullet. FMJ has an exposed lead base.
That'd be incorrect. MC and FMJ are the same thing
FMJ and MC both have lead exposed at the base

MC= metal case
FMJ= full metal jacket [which is a misleading term]
FMC= full metal case [a term that's rarely used]

TMJ= total metal jacket which does cover the exposed lead on the bullet base.

TMJ is available from Federal and Speer as reloaded ammunition; and Berry's and Rainier make plated TMJ bullets available as reloading components

Ye both be wrong :D

MJ Jacketed are just that, a lead bullet with a copper jacket wrapped around it. While MC bullets are lead bullets that are plated with a non-lead substance usually a copper alloy. The T and F are pretty much the interchangable now days as you do not find many hand gun rounds with exposed base. Coated bullets are usually cheaper because they require less copper and less effort to manufacture.

Both Berry and Rainer manufacture Plated or Coated bullets not jacketed bullets though Berry does make a jacketed rifle round.

other than cost, are there significant disadvantages over time to the cheaper copper alloy coating than the copper jacket?

my real question (in my mind) is 'is it worth it to me to worry about the difference?' but since i realize that this is a subjective question i will just leave it at the original question. cost is not so much an issue to me as, at times, availability is.

thanks!

It will depend on the manuf. meaning. There are plenty of FMJ still made w/ exposed base; WW, RP, Sierra, Hornady, etc.

I am not really seeing a difference between lead, plated or jacketed in my XD/XDm-40's for range/plinking use. Not even in what I have to do to clean the firearms.
I believe the quality of the bullets is more important than type for range use.

Every MC bullet I ever used had an unexposed base and were copper plated. Every jacketed bullet I ever used actually had a jacket (duh!!) and an exposed base.

Same here. Wish I could get some more of those 200gr Rainier .45 bullets for a reasonable price. They do well in my XD Service.

I know this is an old subject, but with the demand of ammo these days it's hard to find any 9mm in Ga.
With that being said, my wife ran across some FMC 9mm Luger ammo at a location that had several boxes available and purchased 5 of them. I'm not familiar with FMC and was wandering if these will be okay for the range??
