Need help with reading my loading book

So essentially my question is this: I have a Lyman reloading book. I cast boolits and powder coat. I bought a Lee mold that is supposed to drop 125gr and another that is a 105gr. When I look at the load data, the projectiles pictured don't look like mine. So here is the question, when creating a load do I go with the bullet weight and disregard the shape? How important is the shape of the projectile, as it a wad cutter vs swc vs ball, I have been leaning towards just relying on weight.
