I'm using PMags. My cast bullet is

It's pointed, but the nose is fatter. I can seat it out far enough to touch the lands and still fit in the mag, however, this is when the feed ramp takes a HUGE chunk off the shoulder of the case. Seated further in, shoulder is fine.
With M80 ball, 150gr pulled tracer, 240 SMK's, and these cast bullets, seating various lengths, I get a nick in the neck right at the mouth of the brass.
Can I just radius all sharp edges on the feed ramps without adversely affecting feeding? Just so they're no longer sharp? Forming this brass takes too long to have it damaged like this.
I try to post some pictures tomorrow some time... thanks, Mike
