Homemade 9mm Rifling Button and Barrel

Making a rifled barrel from a Grade 8 bolt. 9x19 9mm Luger

Great work, love the ingenuity! Question though? By having the rifling on the bit and with you pushing it in, is that just spiraling on its own?

[@ottowhack9248]

Yes it is.

What steel was the rifling button made from?

[@ottowhack9248]

It was cut from a injection molding machine ejector pin. The rods I used to push it through are also ejector pins of a smaller diameter.

Hi! Could I ask what is the diameter of the rifling button that you made ? How deep is the groove? Thanks

[@ottowhack9248]

Before I started with the grooves I ground each end down to a size that was a sliding fit in the bore (shown at 0:56). I used those ground ends as a guide to know how deep to make the grooves. Better if they are deeper than needed than not deep enough. The button was made from a 9.5mm (.375") ejector pin. This is oversized. I didn't show it in the video but after making the grooves I ground it to a slightly smaller diameter.

@@ottowhack9248 Thanks for the info!

It is very wrong to use this type of barrel because it must be 4041 steel, which is less ductile
