PGunner:
Do any of you powder coat your pellets and how do they shoot?

I powder coat all of my cast pellets and I've done some commercial ones with good results. I even powder coated a batch of steel BBs with good results one time.

ER00z:
Instead of starting a new thread, I figured to ask some questions here...

Does powder coating change pellet/projectile behavior to any noticeable degree? For example, will the Powder Coating change the hardness of pellets? Will the velocities change from added weight or changes in bore friction? What happens if a hollow point cavity is filled in, either accidentally or purposefully? Is this good for under sized projectiles or loose bores? I could probably come up with many more questions, but figure this is a good starting point for the uninformed, Lol.

Simply out of genuine curiosity, why powder coat airgun projectiles? (aside from pretty colors and potentially cleaner bores)

Roadworthy:
I've not gotten into it yet.  I did get some supplies just no round tuits yet.  My goal is to increase some pellet diameters as I have a couple sloppy loose guns and I've been told coating will increase pellet diameter by a couple thou.  I doubt the coat is any harder than the pellet itself but understand that it leaves less residue in the barrel than lead does.  At the moment I'm in the process of winterizing my place.  With that done I may do some powder coating.

EdinGa:
When I'm powder coating slugs, I resize them afterwards for the best uniformity. I cast all of my pellets with pure lead, and I've never had any noticeable issues with loss of accuracy. They only time I've powder coated commercial pellets is when they were undersize already and it did help accuracy. If you're using pure lead only, reheating and cooling won't change the hardness. Alloys can be a little trickier but slow cooling should minimize any changes.
