Thanks in advance.

OP, I just got my 46B fixed. Would not feed. Turns out there was a round caught in the same area. The round caught in there had a rim that measured about .005 bigger than others. May not be the cause of your issue, but make sure there isnt a round in there and try other ammo to see if it may feed thru there better.

I'm not sure what curve you are referencing and I know this sounds obvious but is the tube clean? Try running a boresnake with a copper brush down it a few times to make sure a piece of lead or other debris isn't holding things up.
