I'm just curious as to the effect of a heavier bullet vs a lighter bullet. Doesa lighter bullet just shoot flatter or is there a difference? I guess I'm just curious as to the theory behing the light vs heavy.

I'm wanting to extend my range this fall. Right now my limit is 150yrds max. I now have a practice range available for me to practice farther shots. The problem I have is when I shoot my gun starts shooting highter. The horiz. line is right on every time but it keeps shooting a little higher each shot even though I clean it. If I put it up and wait the next day it starts hitting perfect again for a couple shots then starts shooting high. What do ya think.

thanks
