I am humble enough to admit that such isn't the case. It's just that I have been down this road a time or two myself. Here is a picture of the 180 grain ones I am using:
The head is pure nearly soft lead so they are good for deer but I wouldn't trust them for bear, and they are choke safe with the vertical relief grooves. I, also, make up a lighter weight hollow base version without the tail that is a lot easier to do since they are just one step in the swaging die and don't have to mess around with building the tail but for serious deer hunting in the field the extra time and effort required to build the tail assembly with the nitro cards and #4 screw is worth it to get the extra weight advantage beyond what is possible with a hollow base stabilized slug.
