Yes, I know the Umarex T4E HDB .68 Cal isn't exactly a pellet rifle but I have found myself needing a less that lethal options to deter coyotes from accosting and killing my friends livestock.
I would like to modify a Umarex T4E HDB .68 Cal to accept an HPA bottle regulated at around 1100psi. There are kits out there but I hate to pay so much for something I may be able to make or have made at my local machine shop. Does anyone know the Rear Bleed Valve size and thread? I figure it is a common sized I can cobble some adaptors together and 3d print something to cover it for aesthetics and added strength...
Again, Don't want to kill the coyotes, just want them to learn to stay away from the farm. I figure a riot ball at around 400fps will leave a lasting impression
Any help is greatly appreciated!
