I had the similar problem with mine leaving scratches/gouges in the bullet.
The problem is partly caused by the feed ramps scratching the ogive of the bullet when being fed up the ramp to the chamber.
The other problem is bullet length and ogive design I found while seating different bullets in search of the answer.
Some times the scratches were not too bad and other times it brought concern to me personally.
I did notice that the lesser scratched bullets came from one side of the magazine for what reason I don't know.
I took a very small 1/2 round fine tooth file and filed down the feed ramp into the upper receiver giving the ramp a longer runway if you will.
Scratches were half of the severity they were when I started.
I cleaned the chamber and bore after each filing till I was satisfied with the bullet.
Hope this may help you out some. If you are not capable of doing this: LET A GUNSMITH DO IT FOR YOU!!!!!! /ubbthreads/images/graemlins/grinning-smiley-003.gif
