Re: Using PB projectiles designed for PP, as GC non PP

I think that if 1500-1700fps is your target velocity, you probably wont need a gas check.
I would suggest you look up information on powder coating cast bullets. Also, there has been a lot of experimentation with high temp epoxy coating bullets as of late which more or less accomplishes the same thing.
Are you swaging the base for the check or covering full diameter and pushing them through the sizer?
I did try some high temp epoxy , but am unable to get bake .Looking for a Oven toaster, but all on hold, as I may need to change houses, and re set up 'shop' soon.
I used the Duplicolour hi temp black spray on a mate's .452/230 Lee TL projjies.They needed a 200F bake for 2 hours-didnt withstand the acetone or sizing test completely. I did lose flakes on sizing.BUT no leading.
for my 404's, plan to enclose the base completely,havent got a sizer modified for them yet.
Am enclosing pics of the projectiles.
If the suggested velocity is safe enough,I may try out a few unchecked, tempted to try a wax/cardboard overpowder wad too. Can never tinker enough...
