First up, get the striker, it's a bowling ball launcher that you can find in the Beaver Creek Lanes in Far Harbor. Follow the way up to the first floor and also pick up some bowling balls. You will also need the Big Boy launcher for this method. Many of you will probably own it already, but if you don't check the diamond city vendor who sells it. Now that you have both guns, go to a weapon workbench and put on the standard launcher for the striker and remove the bowling mod. By doing this the new mod will be available for the Big Boy launcher that shoots two projectiles with its bonus perk. So everytime you shoot the modified Big Boy from now on you will get an extra bowling ball. With the help of an older glitch you can even make this 4 balls per shot. Simply go into any power armor and make sure that you're in first person. Zoom in and out with your weapon, switch to third person and shoot your big boy. This glitch doubles your shots and you will produce 4 bowling balls with a single shot. With this combination you can stack up on ammo very fast and sell it to a vendor.
