I took it out again last weekend and had a few failures to feed with a Chip McCormick Power mag, but ran 100% with an old Colt 7rd mag. After coming back home, I tested the loads by hand feeding them in some of my other 1911s. They didn’t feed all that smooth, so I shortened the COAL .020”
This is a newer bullet that a friend is casting and powder coating, so adjustment was probably needed. The load isn’t burning real clean so it will get turned up a bit. Report to follow.
