Motivated by this thread I just went and did this, and it does seem to help significantly. I just put in my drill press and hit it with a couple needle files, it didn't seem like it was that hard. Didn't try and prime the case I did but it looks like it will be suitably swaged. I also polished the pin with Scotchbrite and that may help.
