Brand your business right. Make sure you have what you need.
The first thing you'll need is a gun, specifically a shotgun. Typically a 12-gauge shotgun is used with a full or improved/modified choke and a 30-34 inch barrel with vented rib. The styles of gun vary from single-barrel, double-barrel, pump and auto-loading with prices ranging from a few hundred dollars into the thousands. Go to a gun shop or sporting good store and tell them you want to shoot trap and they will set you up with something that is a good fit for you.
Once you have your gun you will need shells. There are shells specifically designed for trapshooting. They typical are referred to as target loads and will have a shot size of #7-1/2 to 8 and come in boxes of 25. The amount of shot and the charge may differ from one brand to another. Your best bet is try a few and find something you feel works best for you. If you don't know where to start we have a basic target load available at the club for purchase.
The next thing you'll need is safety equipment. Ear protection is a must on the trap field. Plugs are preferred by most shooters because they don't interfere with the fit of the gun. Sheridan Transit has disposable ear plugs available.
Besides your ear protection you will need eye protection. Shooting glasses will protect your eyes from any debris that may come from the shot or while eject the shell. Today's modern lenses also help with making the targetss more visible.
A shooting pouch is not an absolute neccessity but it comes in handy. The one thing you never want to do on a trap field is cary a shell box and pick shells out of it from the ground, this is distracting not only to you but to other shooters. The styles vary from a simple clip on that holds one box of shells to models that can hold your spent shells, extra shells and even towels and gloves.
These are the basic items you will need to get started but that doesn't that this is all there is. There are gun cases, vests, jackets, gloves and many more items and gadgets available.
