220 grain hornady round nose will not feed

[Fritzcat]

I have dremmel and polished the feed ramps on my 762x39 for the Horn 220gr RN. The first box had around 1/3 exposed lead and fed good. The next box had 3/4 of the nose covered and started dragging. These fed OK in my 300 Whisper then the next box had the whole nose covered with lead. I open up the fed ramps and polished and they would still drag enough to cause them to bounce up and hit the top of chamber and push the bullet into the case. So I started trimming some of the lead off. These bullets have the jacket over the nose to about a 3/16 hole in the point where the lead comes out. With the lead removed they slide right in. I wish they would leave the lead off the tip. If I could find some Sierra I would try them. I had looked at some Nosler 220gr and they are Semi-Spitzer and cost nearly as much as SMK 240gr. so I had to pass on them.
