Hi John, I just PM'd you about the Viper. I can probably make a trap since we are not talking a lot of muzzle energy (my traps have to stand up to a .457 Texan with a 500 grain cast bullet). Just e-mail me with what you have in mind. Shipping cost to your location might be an issue due to weight though depending on what you envision.
Hunter I am working on some additional Ranch Pictures including some aerial footage from my DJI Phantom. Just waiting on a calm day to fly (calm days are rare at my location). I'll get the range mowed again and take some pics there too. Been too hot to worry about the "long range" (400 yards) maintenance this summer. I have been shooting 65 to 100 yards from my covered patio in the meantime.
A front end loader bucket works very well but might not be back yard friendly at some locations. My Kubota has a lot of pellet marks in the bucket
