Many shooters shoot old outdated guns and win shoot after shoot after shoot leaving many with the expensive guns behind in the dust. The investment is low. But soon you will reload your own shells for practice and and cut your cost for shells in half. Singles event shoots 100 targets, handicap shoots 100 targets and double-trap shoot 50 targets. If you can't afford this, no problem nobody says you have to shoot all the events.
Many shooters only shoot the handicap events which pay the big money.
Now, that's an economical sport when you can control the costs. You will be surprised to discover that your costs will come down dramatically, even in your first year of shooting. It's a neat system where the shooter can make money. I know many shooters who have made money in their first year of shooting playing these options. Any prizes you win you can keep or sell and that could put some extra money in your pocket.
