For 50 Cal Air Rifles. You could buy them from amazon but why not just make them.
Created by request. Hope this works for you Mark. I recommend printing the files marked "Vase Mode". When printing in vase mode start with ( 3 bottom layers) ( 1 Shell ) and ( 0 Top layers ). This gave me a strong part with a slight interference fit from my printer. If you have fit issues you can use part scaling in your slicer to adjust the tolerance. For Best Bore Fit print the Bodies Individually. They should hold 170 grains of #6 shot. I also included the Fusion 360 files.
Let me know how well these pattern.
