MJR10,

Sorry, but bows are not rifles, in the sense that you open them up, sight in a scope, and anyone can go hungting with it. Also, any Mathews Legacy will be no better "tuned" out of the box than a new PSE $200 combo right off the shelf at Wal-Mart.

First off, your field points and broadheads may NEVER shoot in the exact same spot. You can go crazy trying to achieve it. If you have good flight with broadheads, just change your sight settings for hunting.

Second, to achieve good broadhead flight, it is critical that you have good arrow spine. That means having the right stiffness arrow to match your bow. Perfect spine is a FINE adjustment, although "close" is often good enough. The better your spine, the more forgiving your setup, and the easier time you'll have swapping to broadheads. IF you selected the right carbon express arrow and you are close to being the right spine, you can adjust your bow's draw weight to control how much force is shoved into the arrow.

A quick and easy way to test your setup (especially good for tough carbon arrows like yours) is bare shaft testing. Take one or two arrows and cut the fin portion off the vane (leaving the base and glue on the shaft to maintain arrow weight.) Shoot your fletched arrows and bare shafts (both with field points only) at a target from about 10 yards. If your bow-to-arrow spine relationship is good and your centershot settings are acceptable, the bare shafts will hit close to the fletched ones. If they don't hit close, you know that your fletchings are having to do too much work to correct the flight of the arrow after it leaves the bow.
