In this tutorial we create a nice shiny rifle bullet

First, we are going to create the bullet slug. Create a spline that resembles the one on the picture.

Apply the Lathe modifier to the spline and set the segments number to 16. If you don’t get the object like on the picture, try clicking on the Min/Center/Max buttons in the Lathe modifier properties until you get it.

Add the MeshSmooth modifier to the object and set the iterations number to 2.

Next, we’ll make the bullet casing, so create a spline like is shown in the next picture.

Like with the slug, apply the Lather modifier with 16 segments to the casing spline.

Add the Edit Poly modifier and go into the Edge selection mode. Select the edges (shown in red in the picture) and chamfer them a little bit.

Switch to the Polygon selection mode and cut the long vertical polygons in three spots, as in the picture (probably best done by using the Slice Plane in Edit Poly options).

Finally, do a little more chamfering at the bottom of the bullet casing.

Add a MeshSmooth modifier to the casing (Iterations: 2);

Now, let’s focus on the bottom of the casing. As you can see, we have a hole that we need to fill. That is the part where the trigger hits the bullet casing.

Create a cylinder with 16 segments in the center of the hole and chamfer the rim edges.

Add a MeshSmooth modifier with 2 iterations.

Next, we will add some marking at the bottom of the bullet caseing. Create the text object with a capital letter O.

Add an Extrude modifier on it and extrude it for a considerable amount.

Create two more text objects, another one with a capital letter O and one with a number 2. Also apply the Extrude modifier, with identical settings as before, onto them. Then arrange them to the positions like in the next picture.

Select all 3 text objects and the bullet casing and convert them to Editable Polys. Next, attach the 3 text objects into one editable poly. Select one of them, go to the Editable Poly options, click on the Attach button, then click on the other 2 text objects. Click on the Attach button again to exit the attach mode. Now we have a one text object that combines all three characters.

Select the casing and go to Create Panel -> select Compound Object from the drop down list -> click on the Boolean button. You will get a new set of options. Switch the Operation option to Cut -> Refine. Click on the Pick Operand B button and select the text object.

You should get something like this.

Next, apply the Editable Poly modifier to the casing (this is necessary because it changed it’s type from Editable Poly to Boolean). Turn on the Polygon selection mode and the newly cut in letters will be automatically selected. Extrude them inwards a little bit.

That’s it. Model is finished. Now all that’s left to do is add a metal material to the whole model or a material with clay like color like this:
