As I said before reloading reduces cost and control variables such as pressure. Additionally one has more flexibility to create combinations of shot weight, pressure and velocity not available of the shelf. One can also trim hulls and make their own short shells easily. I just ran the reloading calculator on my most often used target loads and came up with my cost for a box of 25 as follows: $3.59 for 20ga 3/4oz, $3.79 12ga 7/8oz, and $4.12 for 12ga 1oz. I use brand name components and could save more if I bought in bulk. Velocity for these loads is beteen 1145fps and 1200fps and pressures in the 12 around 7800psi and 9500 in the 20. I also find reloading to be relaxing and satisfying past time.
