Can you use any brand or colour of powder coating powder?
A more difficult one, if I PC but don't GC, what sort (aprox) of speed and accuracy can I expect but still no leading?
I've never cast anything smaller than .3 a ,22 would be a couple of drops of lead and keeping the mold at temperature could be difficult. In reality you will be making somewhere between a .22 and .22 magnum velocity wise. Conventional wisdom says you will get to about 14-1500 fps without gas checks before you encounter leading and up to 2000 with gas checks possibly a bit more with a suitably hard alloy which will resist stripping at high speed especially in a fast twist barrel . Powder coat keeps the lead from contacting the bore so acts a bit like plating enabling higher velocity. Gas checking really just protects the base of the bullet from melting and I doubt its needed with powder coat.
I've cast a heap of 22 Cal bullets intending seriously testing them in my 22 Hornets.
All are powder coated
And gas checked because that is what the moulds were and I wanted to run them at a reasonable speed
Three different bullets
All are sized for consistency
Initial test results were disappointing in several known accurate 22 Hornets.
Then I got given a box of 1000 22 Hornet hollow point jacketed bullets and lost interest in cast small caliber cast bullets.
Below 30 caliber I'm not sure casting is such a good thing unless you have a very specific high volume use that cast lead is suitable for.

Thx for the help.
Think I will have a crack at PC for my 30.06 first. Have been casting for that for some time. Mainly just for plinking/practice. Then consider the 223 later.

Light Ford blue coats best
Gray looks like lead but doesn't coat as well
So gray mixed with white looks good and coats reasonably well
But Ford light blue is the very best
Don't ask me why
But it is
Commercial PC bullets from Hawke River Bullet Company, sold here by Delta Mike, are rated to 2200fps without GC..whether they are accurate at that velocity would be a different matter.Quote:

Have the same for e.g. 303 Cal
@akaroa1
Thx. Just the sort of info I'm after.
Green is the new blackAttachment 258707
The cool blue is good too.

I can barely get my gas checks on when they're raw.
I just clip em on before 1st sizing. It doesn't react with the powder so I stopped even wiping the powder off the bottom
Love that huge hollow point.Quote:
