I too have tried my own Powder Coated projectiles in my .357 Sig loads--With little to no success..
For ME there is just not enough space in the Sig neck to hold the " SLICK " Bullets.
I do not remember the Lee mold #, but the .356" diameter projectile that I used DID have plenty of contact with the sides, but just not hold the bullet tight into the case.
The same bullet runs GREAT in the 9MM loads..
Again, you may have a better time at this than me??...Bill.
I made some white 9mm powder coat bullets a while back. I will look and see if I still have any of those. 125gr lead PC but they may not be display quality. I found with really light colors like yellow and white the darker bullet may show through in spots.
Those sure are pretty!
You are too kind. That picture actually reminds me of the old MB game Mastermind. The younger folks probably won't know what I'm talking about LOL. There is actually a reason the white bullets are in the back row. I experimented with it and the white color was difficult to work with. They look good from a distance but not so much up close.
I have some white bullets left over from when I was testing it. I can pick out the 12 best and send them to you on my dime if you want. Use at your own risk etc, etc. They are white but not perfect. I would also be willing to send some white powder coat paint along with them if you want to try your hand at it. Just let me know. If they don't serve your purpose you can always just throw them away. I have lots of colors if there is another color that might also suit your purpose.
Thank you for the feedback. Ultimately, these will be "display" rounds so I only need a dozen of them. Where did you find the projectiles?
