This is for an arrow, the rear fits into the hollow part of the cylindrical sabot, while the front halves go over the front part of the arrow to keep it centred.RJB INDUSTRIES wrote:What have you made to center the ammo while inside the barrel?
For this style, the projectile fins are the same diameter as the barrel so no need to keep it centred, all it needs is a disk to push it.
