want to try them, but wondered if they can be a problem.
Without specifics, the general guideline I can offer for using any coated lead bullet is, as already mentioned, to exercise care not to scrape coating off the bullet base.What pistol, bullet weight/nose profile and powder?
What velocity are you trying to obtain?
Can you explain why?I learned today to NOT use the Lee full length sizer/taper crimp die on copper plated bullets.

And since coated bullets are usually sized larger like lead bullets, reference lead load data for load development and powder work up.
Does "blue bullets" refer to a brand? ... or a type? ... or just a color?any problems loading 9mm blue bullets?
Yes - https://thebluebullets.com/Does "blue bullets" refer to a brand?
That is what I saw. I don't think M-dies were created with lead or coated lead bullets in mind.The only problem I had with them is using the Lyman M expander. I would get coating scraping off from the shoulder created by the M die.
Only in the way that any other coated bullet can be.want to try them, but wondered if they can be a problem.
I learned today to NOT use the Lee full length sizer/taper crimp die on copper plated bullets. I would hazard a guess the same would go for poly bullets as well, or at least use caution trying.
Can you explain why?
To me, FCD for straight walled semi-auto pistol cartridges was meant to be used as a "finishing die" that corrects out-of-round/out of spec finished round that resulted from tilted bullet during seating, out-of-round bullet, uneven case wall thickness brass, improperly resized brass, etc. that taper crimp die would not address.I kept getting loose bullets after using the FCD
