So my first attempt at cast in the M1 was not terrible.
I basically found the point of function.
37.5 grains H4895 powder and either a RanchDog 165 grain flat nose or 314299 sized to .310 functioned 100%
I don't have the ability to crony these loads just yet but and have not put any real target time into them. That's Next.
Alloy is currently WW+2% water quenched.
Questions
1. what is approx. velocity range for these bullets and powder charge?
2. Will COWW and 2% tin alloy do well or will a harder alloy be better?
I plan on using another garand later that I know from testing functions down to 35 grains of H4895 but it has some mechanical issues that need to be addressed before its back on line. that will be a while down the road. So I have my next M1 in line for some fun.
The ranch dog has done well by me in my 03a3 even pushing it as fast as 1800fps with COWW water dropped gas check and LLA. barrel is minty clean after. Thank the gods I have had zero problems with leading in any rifle so far.
