I agree weighing is futile. I will have to measure a couple bores to find the largest one. Out of my 11 9mms one should be a little bigger! The one that the bullet did stick was in a Taurus 99 and it stuck almost exactly in the middle and was very difficult to pound out. I have a collet puller but it just doesn't get a good enough grip - I used a taper crimp to make sure these rounds would fit a tight chamber. Wish I had a short barreled 9mm revolver - they might actually get out of the barrell. Maybe a good excuse to but one?
Live and learn I guess.
