A boomstick is a great barrel........
Tips here:-
1. Only use good quality paint.
2. Check your velocity with a cronograph. Set it to around 285.
3. Keep your barrel clean AT ALL TIMES.
If you have a break in the barrel, just firing another ball will not be sufficient to clean it. Use a sqeegie...
Setting the velocity lower will not help with 'spin off' or whatever you called it. Just KEEP IT CLEAN.
