Got this cartridge and I want to rechamber my M4 wannabe for it. A few questions;
Can I use a cast bullet?
Will a spitzer shaped cast bullet work?
Will I need GCs?
Will the 7" twist stabilize the cast bullet at 9,500 fps?
Will COWW alloy work if I HT it?
How about PC?
Anyone know where i can get cases with SR primer pockets?
