Sorry, but I can’t answer that question. I haven’t actually cast anything with those moulds yet. I have to do my casting outside, and with the cold winter weather, my casting has been on hold for quite a while. Last summer and fall, I was working primarily with cast hand gun bullets and load development.
I bought the NOE 60gr RN-GC (SAECO #221) and the NOE 70gr RN-GC because I thought that they looked like the best match I could come up with for my 5.56 AR’s chamber dimensions. I won’t really know any more until the weather here warms up more.
