Well side by sides do kick, side to side. I use that to get my second shot off quicker. You shoot the barrel which will naturally move your barrels in the direction of the bird. I might be using the wrong barrel first but get my second shot off so quickly, the second shot stream often merges with the first, to create a wall of pellets birds can not get past. Makes my side by side almost into a light speed weapon. I’ll circle back with the fuzzy math when I leave my basement to walk the dog before he bites someone else.
