nitro450expJ&L cast bullets.
Hello all,
Just bought some J&L cast bullets .475 off of GB.
All searches come up that these were made by Jim Cox who has since retired.
PGB Superior comes up as having bought out Jim, but have been unable to make contact with them.
Bullets appear to be moly coated with 4 grooves 520 gr.
Anybody got any experience with these?
Do I need to size them ?
Do I need to lube them ?
Any load data or sources for load data ?
I will probably try Accurate 5744 reduced laods.
Any and all help welcome.
Thanks

Bill CooleyWhat do they mike? What is your actual bore diameter, what does your bore measure when you slug it. I think you could be .001 to .0015 over with out any problem.
If they are moly coated they should be ok.
