so i picked up an "ammo plant" today. whilst i'm at the retailer i see a great deal in 380 ACP projectiles but unlike others i have seen that measure .355 these are .356. What if any serious difference does this make. Thoughts appreciated on bullet diameters as well as tips RE the reloading system. As a note i am well aware of the web site "Ultimate Reloader" i have also personally on my Lee set up loaded over 33000 rounds of ammo ranging from 9mm through 50 BMG.

Im not familiar with loading 380, but if you're following a load recipe, you should be fine. I'd imagine .001 will increase chamber pressure, but it must not be much, because both diameters are marketed for use in 380 ACP.
Are the "projectiles" you bought lead, copper plated, or copper jacketed?
Lead are traditionally .001 or .002"over jacketed diameter but a .356 jacketed bullet won't change anything to much.
I wouldn't be to worried about loading them, if the are jacketed they will raise pressure like Nemesiss said so you could stay away from maximum load with them.
If they are plated or lead they are supposed to be .001"over jacketed diameter.

they happen to be plated, I guess i'll just have to "bite the bullet" and try some. they'll be for my new Glock 42 which i have heard have been having some issues, though mine works fine i know pocket 380s can be a little temperamental.

Your .356" bullets may be heavier than you want. Check for proper weights.Best
