You made an excellent choice for a trap gun. The SBT is a specialized machine. The BT 99 is a gun you could shoot for the rest of your life.
Enjoy the addiction. I was happy to find a check in the mail from my club today. Shot the club championship, and had to split before they totaled the scores. I shot far from my best, but still won a little (very little) money.
I really really wish I could settle down enough to shoot every Sunday, but alas my job keeps me on the road too much. Had someone point a gun at me at the club closest to where I usually am, so don't go there now.
Congrats on the Browning, and remember the three rules of trap, keep your head down, keep your head down, and keep your head down.
Have heard the best way to learn to do that?? Put a 20 dollar bill between your cheek and the stock. If the bill falls to the ground?? Your instructor gets to keep it.
