It should last longer than that.
I've yet to use any lube at all in loading many thousands of rounds of .45acp, 9mm, .45 Colt, .44mag, and .38/.357mag.
I save the lube for .30 carbine and bottleneck rifle cases. My carbide sizing dies for pistol don't need it and I haven't noticed it helping enough to be worth the trouble when I tried it.
