It surprises me at how many guys will buy cases of shells to try because they are cheap. I can understand grabbing a couple boxs to try. I find something that works and I tend to stick with it for the most part, I'll buy a box of other shells to pattern and try but not cases. 20 to 40 bucks extra for shells over the course of the season is cheap to have a good load you are confident in. That's why I reload so I can have confidence in my load to do its job, the bad part is sometimes I have to look in the mirror and say shake yourself and hit something.
