Does anyone do the "Shake and Bake" style of powder coating?

Yes. I've had good results using powder and plastic balls bought from the guy on cast bullets forum in the states. His username is Smoke4320
The powders/BBs I used:
RAL 4006 Traffic Purple
RAL 6018 Yellow Green
RAL 5012 Carolina Blue
1000x Black Airsoft BBs
There must be UK equivalents that work but I just wanted a tried and tested option. I shake/spin in old cylindrical yoghurt/ice cream tubs. Guides online for the type of "plastic" the tub needs to be made o (a "5" inside the recycling emblem, from memory.)

Yes, I have done before with powder I bought off eBay. I used an ice cream tub to shake the bullets in. Very easy to do. Less is more with the powder.

Thats very helpful. Any ideas how fast / what pressure you got to?
Best wishes,

I will find you a link to a current seller. Make sure you choose a Gloss Polyester powder:
100g Powder coating samples - ALL COLOURS - Polyester | eBay
Cure Schedule:232.2°C (450°F) / 15 min. Low gloss silicone powder coating formulated for prolonged service. HIGH TEMP POWDER TEXTURE.
www.ebay.co.uk
Otherwise I can send you some green powder if you send me your address.
I got to 2700fps without any leading issues but POI was quite far off and didn't investigate further. 20:1 Pb:Sn alloy

Cheers! Do you know what Shell House usually use in their .44 Cal 300gr per chance?
Sorry I'm not an expert in bullet metal. I'd expect their alloy is harder though
Some powder coating pointers from my experience:
Line your tray with greaseproof paper or silicone baking sheet (not tinfoil, as bullets stick to it); Don't bother standing all bullets up in the tray, it doesn't matter if bullets touch each other; fully cover tray with tinfoil and crimp it around edges so that fumes don't escape too much - polyester fumes are not good for you; bake at high temperature for about 10-15 minutes; take tray outside and fill with water to cool; break bullets apart and resize using Lee liquid alox or wd40 etc as lubricant - bullets will resize very easily.
Hope this helps. I didn't find I needed to use BB's - more faff to separate before baking too.

I use this system, not shake and bake but gets a really good even coat on everything and super simple to use..probably best with a gas checked projectile as I sit them all up on the baking tray before powder coating them..haven't had the chance to chronograph the rounds yet but its on my list of things to do and recover some projectiles to see how they hold up after they have been fired.
Great choice of colours with this powder coat system aswell

I'm not a practitioner, but I think it reduces lead fouling in the barrel. i.e.Some folk with 444, or 45/70 marlins and the like, who cast lead bullets to reload us it, especially if their reloads are fast. eg: 2000fps plus.Eeerh, what‘s this powder coating good for please?
I like the colors though.

Not done it for a while. But I used large plastic yougurt pots as the shake container.
I would get a lot of lumps and blobs from bullets touching during the bake. Also from build up on the mesh I was using as the tray.
But would run them through a simple Lee sizer die (needs a bit of lube, a touch of trex tumbled in whilst still warm works well), which fixed most of that.
Powders are random ebay buys. Heard that some black's can be abrasive. But not really done much research there.
Max I push them too is about 1700fps, which is .223 rem gallery loads. Not gone faster as that is the limit of the range I use them on.
