I think that everyone is pretty right on, but one thing to remember is to find something that shoots accurately. Example: I have a Winchester 70 that some guy cut to 18" neat gun, and super accurate - with bullets OVER 150 grain. 165-180 is below MOA from factory ammo. 15 is a little over MOA. 125's are just not accurate, and I have a friend who has the same expereince with his Savage 110 LE w/20" bbl., so find something that is accurate more so than weight.

Psalm 19:14-May these words of my mouth and this meditation of my heart be pleasing in your sight, Lord, my Rock and my Redeemer.
