I have a question about powder coat.

[AZPaul]

Why use a powder coat paint, why not just any old spray paint?
Just curious.

Regular paint will not hold up as the bullet travels down the barrel. Powder coat is crossed linked polymer when cured in the oven.
Read some on powder coating. It is easy to powder coat a few bullets in a #5 bowel with some plastic air soft type BBs.
A small cheap dedicated convection oven can cook the coated bullets. I started with an oven from Wallmart that cost $45.00 new.
Lots of info on the process of powder coating on this site, read and read some more, not hard to go and the coated bullet works very well in hand guns.

I thought that was the case. I have some .40 lead cast I want to use in my 10mm. I tried lee lube on just 40SWs and it leaded up so badly the rifling disappeared. I was going to try powder coat on my 10mm.

This sounds like a fit issue. Regardless of lube or coated, the bullet needs a good fit. Glock OEM bbls are pretty generous & a 0.401" bullet may be too small.

Powder coat will add .001 to .002 to the boolit if it is too small.

PC will not compensate for poor loading techniques and poor fit. Some try to use it as a crutch for poor techniques.

PC is a high tech replacement for old tech grease lube. It does add 1-2 thou as mentioned but should not be used to compensate for ill-fitting castings.

Since you are here in AZ, PC will allow you to use boolits in this wonderful summer weather without the worry of stick/ messy/greasy boolits! And no grease smoke and no leading (if fit is correct)!

Go fir it..........I have been PC'ing for years now and love it. Haven't shot a "greaser" in many years. Never any leading in my many 223 thru 45 cal gun barrels.

I'm pretty sure it was the Lee sizing die sizing them to small. I used, I had molded some Lee tumble lube bullets but want to size them anyway, so I used a Lee sizing die. It sized the bullets down to less the .400. But I was just to paranoid to try it again without sizing them this time and using a better coating of some sort. It took forever to get the lead out. I would like to fix the sizer though, make it size to .401.

There is always comments about bullets need to be .001" to .002 over groove for cast bullets. Would someone comment if it's better for cast bullets (PC or lubed) to even be .003" or so over groove rather than groove or less?

Too big is only an issue if the round loaded won't chamber. I run 0.357" bullets in all my 9mm.

Yes........it all depends on what your gun likes to eat.

By and large I do not size pistol bullets. I shoot them first, and if they won't behave, I experiment with things like sizing.

[Bzcraig]

All the info above is correct but what is missing is it all starts by slugging your bore. You may very well cause yourself a bunch of grief if you try to avoid this step but if you start there you will likely save a bunch of time and money.

If you shoot them first, how do you find them if they need sizing?

[AZPaul]

Wouldn't a Lee Factory Die also size the a lead bullet down?

It can indeed but if you don't know what your groove diameter is or your as cast size, your just groping in the dark. How would you know if the factory crimp die is sizing down your boolit if you don't have anything to compare it to? At this point all you DO know is you have a leading problem that can be caused by anything at this point. It is best to take a practical, methodical approach which starts by knowing your groove diameter.

I know my lee bullet sizing die is under sizing them. What is the best way to adjust it?

Try shooting them as cast.....

Works in rifles also
