It is possible to consistently make the 1 ball on the break in the side pocket. The most important factors are the contact point, and the speed of the break.
In this diagram, I’ve drawn a line through the 4, 8, and 1 balls. Aim for the point on the one where this line goes through. This will be slightly left of center as you look from your rail bridge. Apply just a touch of draw. USE NO ENGLISH! Using english on a power break will only cause the aim to go off and waste energy. The CB should bounce to the side rail you broke from and back out to the middle of the table. Play around with the speed of the break, keeping the contact point the same, and the 1 ball should head toward that side pocket.
