I shoot bows often at under the reccomended suggested weight. Never have an issue with it. I actually shoot spots with a bow that is rated at 50-60 lbs and I shoot it at 45 lbs.

I have shot several bows at extremes of draw weight both way over and way under what the bows are rated at, never had an issue with consistency or accuracy.

The reason you shouldn't turn them out that far is because you run the risk of the bolts coming out of the riser and the bow will explode on you. ALWAYS know how many turns you can back a bow off from bottomed before messing with it. They are not all the same. I saw someone on this site I believe tell someone they can back the limbs off about 6 turns and be safe. That is crap, try it on a bowtech and see what happens. I would suggest wearing a helmet and heavy clothing when you do it though, because it will come apart on you.

You don't need an expensive bow to shoot well though. Most of the records that have been set and yet to beaten were done with old bows that would be considered cheap and junky by todays standards.
