I also have some FC and WCC brass. Do I reduce the same amount in these cases also?
I am aware of web thickness issues with FC brass and plan to build the tool DryFlash3 used to measure the thicknesses.
Thanks for your help in advance.
With 223 brass, there are just a couple of heavy brass headstamps to worry about. PMP from South Africa is one I have loaded.
With US mil brass, the loads are the same as commercial 223 cases.
Which means that Win and LC 223 cases use the same powder charge.
Totally different story with 7.62x51 (308) mil brass. Drop charges 10% from commercial case loading data. All cases are heavy.
The blanket statement is just CYA in case someone doesn't remember which caliber (7.62x51 Yes, 5.56 No with exceptions) that you do indeed need to drop the charges.
