Sizing for pistol?

[SteveK]

I cast these for cowboy action shooting in my 357's. They are sized then tumbled with hexagonal Boron Nitride.
Slick as heck they are.

Never heard of hBN. Is it better than molybdenum disulfide? I assume the coating process is similar.

Thanks for the great information!

I have a NECO moly coating kit which I used 20 years ago for coating J-words in my varmint rifle. It uses steel balls and a tumbler to apply the moly. The coated bullets are then tumbled in carnuba wax to seal the coating and make them slightly cleaner to handle. They worked well, more consistent velocity, less fouling, and smaller group sizes.

I moved in the late 90’s and got away from shooting. Just getting back into it and starting to cast. I tried Lyman’s black goo (moly bullet lube) and it works but is messy.

HBN seems like a better solution than moly for coating. I never considered tumbling cast bullets as I thought they would be excessively dented by the steel balls, but your 357’s look great.

I am glad you “rambled”

I forgot to ask what mold those came from. I only have SWC’s and they do not feed well in my lever gun.

I know it's a Lee for .357s @ 150/158 gr bullets. I tossed the box ages ago. Sorry I can't find more details about it.
