The 1 in question is a 223 that I chopped, filed, sanded on for a couple hours today. I attempted the well document method of using brass machine screws and grinding compound for crowning.
After going through 6 brass screws and out of desperation trying out a steel screw (all told at least an hour of "work") I have absolutely zero crown on my barrel.
Is this a Saiga issue (harder steel/chrome lined barrel)? Or am I'm some sort of idiot? Don't answer that last question.
For reference here it was my barrel looks like after I finally gave up 30 min ago. (Ignore the lapping compound in the barrel, I haven't cleaned it yet).
Anyone have any idea what the issue is?
