Has anyone used .355 (9mm) projectiles when reloading .38 special (.356 to .357), I do not have a ton of .356 projectiles and want to reload a batch of .38 Special, .38 +P and .357 Mag bullets.

The short answer is not really
Issues:
1. the crimp die being able to put enough tension on the bullet to prevent setback
2. lack of a cannalure on the bullet to roll crimp them
3. the .001 of slop may cause accuracy issues
4. if the 9mm bullets have exposed lead bases be careful pushing them as full 357 loads

I've done the reverse... using .358 sized lead in 9mm for bowling pin loads in the past. That worked ok, once I found something that cycled.
Generally I shoot jacketed bullets in 9 mm.
If the bullet is soft enough, it will work via obturation, but you will have leading issues.

I found more data indicating its not a good idea, mostly with potential setback on the cases.
