Newer modern crossbows are built as "hot rods", engineered and designed to shoot just shy of a "dry fire".
Another reason why I don't like the one that I own is that I can't enjoy shooting it, because it only has so many shots or shot life in it, before nearly everything has to be replaced.
I called Ravin tech support and asked if there would be any warranty issues, if I built a heavier Ravin bolt so that the crossbow itself wouldn't be as loud, last longer and get the use of the stored energy in the limbs. They said that would be a great idea and they didn't have a problem with it.
Adding weight tubes, brass inserts and heavier tip weights were all good ideas to them. It will definitely effect trajectory and the scope speed adjustment dial will have to be turned down to accommodate the slower bolt speed. I think this would be the way to go, if I were interested in shooting it more. However, I have my recurves and longbows to keep me entertained.
Crossbows have put a lot of people in the hunting woods and that's a good thing.
Paying over a grand, like I did, is silly. I blame the commercial hype selling point of the "holy grail" of speed and flat trajectory.
A person could get more shooting enjoyment out of a crossbow, if they purchased a slower speed model and/or one without the preloaded limbs. A standard limb without the wheels/cams would have a longer life span, be just as accurate and not need as much costly maintenance.
