"...because it can always be put back..." Yep. Easily and inexpensively too. Taking the pressure point out is the only way to find out of your rifle likes a floated barrel or not, as well. Not all rifles like it. If it doesn't you just put a dab of bedding material(usually just 2 part epoxy with a fibreglass filler.). JB Weld is epoxy with powdered steel. It'll do as well.
However, if you're going to do it, you might as well glass bed the thing at the same time. Glass bedding isn't difficult either. Buy an Acraglas kit and follow the directions on the box.
Pillar bedding is steel(usually) or other metal, um, hollow 'pins' that have the stock screws going through 'em to keep the stock separate entirely from the barreled action. Slightly more involved to do.
Neither of 'em give a 100% guarantee of better accuracy, but they will give more consistent groups.
"...a 100.00 bill..." A what? snicker.
