Pathfinder 1E [3.P] Throwing stuff and improving its range

[ImperatorK]

I have a War Hulk Hulking Hurler and I want to increase his throwing range. His extreme Str should allow him to throw fairly heavy stuff very far, but by the rules he can only throw at a max increment of 50 ft. in general (10 ft. x 5) or 250 ft. for lighter stuff (50 ft. x 5; War Hulk's Mighty Rock Throwing feature) (unless there's some rule that I don't know about that increases throw range based on Str or something).
My first option is the 3.5 Far Shot feat. Are there any other?
