Hey Val, another Homebrew request. The Feat "Sport Hunter" (Page 25 - Galaxy at War) gives benefits to people using Sport Blasters/Rifles and Slugthrower Pistol/Rifles. I'd like to include Repeating Crossbow (Galaxy at War - 39/41) because in its description it refers to the weapon as a "is popular...with hunters who desire an additional challenge." I think given this I should be able to included it as a primitive rifle, and just apply the slugthrower rifle bonus, which changes it from a 1d8 to a 1d12.
Does that fly with you?
