RE: An end to tuning?
Gentlemen
It was sold as an entire bow. The riser was designed arount the tubular rest and visa-versa. The different size cams gave it a perfectly straight and level nock point which is best for this type of application.
I also had a different tube that did not shoot arrows. It shot a rectangular 2 piece sabot that was filled with shot and I had made videos of us shooting trap. The speed of the shot was 1/4 to 1/3 the speed of a shotgun and it was difficult, challenging and one heck of a lot of fun. It was definitely something people could enjoy year around especially during the off-seasons. I look at archery as basically a "snowmobile" sport while the ShotBow could have added a "waverunner".
