Deus Machina

My dad just bought a 22/45 MkIII for my birthday, and unfortunately no place around here will let you test fire before buying, and--understandably--won't let you load it up to check.
But it looks like it's scraping a good little flat onto the nose of the bullets when it loads them, and I think I've tracked it down to a couple spots--the tiny lip where the feed ramp meets the chamber, and the sharp edge of the slightly-too-short feed ramp. It's worse when they go sliding up starting at a low angle, and nonexistent when I start the round in by hand and let the bolt shove it home.
i trust myself to a little basic 'smithing with a file--I'm a machinist by hobby--but I'm asking the experts whether carefully rounding the feed ramp into the chamber will break the seal at all or not, or adversely effect feeding.
Now, if I can figure out how to ease the edge on the bottom of that ramp...
